tory burch bargain The process of a complete mobil

thirteen, test mode and change the mode
or plastic parts as an sample, test mode and change mode is that suppliers after completion of the mold making plastic parts and molds try trimmed to meet the design requirements. tryout before customers will chase the other parts together samples When test mode in conjunction with design engineers to model plant,young nfl jerseys low 70 Interview Tips, structural design engineer on all accessories for mounting a single product inspection and checkup, the appearance of failings in a single product, including inspection and check the size of inspection, real equipment is to check all the parts in accordance with the actual production assembly sequence for real equipment, identify the problem. all questions were listed, and the coordination model plant to determine the improvement of programs to improve the time and responsible for improvement, design companies and controversial issues mold factory has made the final by the customer resolved to sign copies and discuss the results in triplicate to pay clients, design firms and dead plant were maintained to remain at the end, design updates to mode foundation of the discussions drawings, plans to issue a formal change mode, change mode to mode part of the diagram includes a careful text illustrate the need to change parts of the 3D model drawings. 3D drawings required to mode part of the required red flagged. micromanager point to mode problems, not disregard.

; fourth, after the pilot example
improved test mode will repeat the procedure can be tested, but this test mold the upper and lower shells and other exterior accessories can cook surface treatment (such as ID are apparent on the surface of artwork injection, over UV, oxidation, drawing, screen printing, electroplating, laser engraving) for further real equipment, real equipment is acknowledged if correct, you can plan a trial escape. pilot can not be installed can be found a few problems found, the number of trial production is generally 50 to 100 units, arranged in accordance with the actual production of the assembly production lines, pilot customers in conjunction with the structure when design engineers to assembly plants, design engineers made it clear from the assembly sequence and precautions, assembly plant by the PE Engineer arrange the production line arrangement, each guide operator to determine the correct operating practices and standards, engineers need the value of pre-PE completion of each assembly station operating directions. in the assembly plant for the assembly try to be brief, the model plant materials have been affixed to the housing, the metal piece from the mold factory has also been hot melt onto the housing, the assembly plant at the peak of Load button on the housing, board, co-shell, locking screws, setup the lens, the final test, packaging on it.
when the pilot issues identified by the structural design engineer record, if you need to change modes, from structural design engineers figure out the change mode, change mode to mode part of the figure includes a detailed text description, need to change the mode part of the 3D drawing. 3D drawing requirements change mode part of the required out of red VI. notifying suppliers to improve and follow up the progress and change the mode to mode results, change the mode after the completion of mass production.

; fifth, production
after reiterated demonstration, revision, testing , modified, structural design engineer the results of hard go is after hours bring an end to ..., always the problems have been addressed before mass, and if there is no problem, the process of production can do without the participation of design engineers, according to the current market conditions, the common price of 800 yuan left over mobile phone sales 5K, customers can revive the spend, and then there are more orders, the customer may have earned. products hit the market, a reflection of the mall, customers may make some revisions, design engineers do the proper rejoinder to it. penetrate their mobile phone design hot in the market to purchase, the kind of feel like their children complimented by others as extremely cozy.
VII. offer map data compilation
do here , mobile phone design a transient close, do first important thing --- to offer plans to cater plastic mold, plastic mold production needs 18 days know next to nothing of, this is the top precedence of the whole mobile phone project, Prior to this, the client chose prototype factories need a few days, first the structure initially completed to the customer to contact the supplier, the process can shrink the time of the project, the use of purchaser contact the vendor a few days, we can optimization of the production, evaluation and amendment, and other customers selecting the suppliers, we also completed the structural design, fair into the mold and mold supplier evaluation stage.
; should be eminent that the plastic mold plastic parts offer plans embody 3D map, BOM and ID tagging process. In order to data security, do not offer a do not give plastic parts, plastic parts need to purchase one less and converted into STP format is best, only offer advantage, inconvenient, for other purposes. BOM chart only to the plastic part in order to avoid error rates. The on message only to the customer, the customer to contact the supplier, usually design company Business customers are not involved in this one.

eight, structural design optimization
Well, now we can perch down on their own to optimize the structural design, and design to chance a product, there are many issues that we need to calculate and prevention, the need for hardware such as ground surface; board and Shell How to match between the body; how to increase the strength of the shell; shell how to improve the system to do and so easy to die.


three mobile phone to get the shape of design guidelines to determine
ID, the first will limn the idea, the next focus selection program to determine the next two-three sketch, it is necessary to meet customer requirements of creativity,有孩子的看一看？绝对有益, but also between the two three sketches alter in style, and then cultivated on the machine, drawing a complete machine renderings, as distant as possible for the ID during the MD to provide technical the support, such as art can achieve, the structure can do a little thin, ID to complete the whole effect of adjustment by the customer and screening plans to finalize the program can start to make structural modeling was transferred to MD.
IX, the structure of each structural engineer review
design made out of , the aggregate can not have their own problems that need to check other engineers, then, in which the different positions, different angles of reconnaissance, there will be obtained to determine differences in wrong on the change, took out a dispute answer can make the level of drawings to a higher class. the review are the other design engineers first by drawing the first trial, the trial took almost half a daytime to daytime, the need for drawings in order of appearance, procedure evaluation, components of the upper shell and lower shell components, surface technology, the feasibility of the mold, to generate one by one the order of assembly of a comprehensive inspection, and difficulty smudges recorded. and then the second stage --- a collective review, the Department of the collective assessment of the structure is full and pertinent ID designer to participate in the appointment, the issue will be listed first example, we express their outlooks, mutual understanding, either to ensure the drawings issued to the highest level on behalf of the company, but also for structural design engineers a opportunity to study and promotion, in Shenzhen, the extra is a large design fixed, the more attention to the role of the collective assessment.







XI review
structure Shouban mold making is not required 4 days you, this time we can mark the ID process, BOM and 3D drawings to the customer, the program companies and the assessment of selected model plants, the review usually takes 1 `2 days, customers have their own technology if you can re- to check the program the company can adopt the antenna signal to assess latent problems, mold making plant will be possible to mold the views put along a number of improvements, and improved feedback to the design. If required, the customer in conjunction with design firm and model plant with the meeting to discuss the views amend plant model, a model problems that need attention can be put along, design and mold factory controversial issues a final determination by the client to discuss the results in triplicate to pay clients, design firms and Save left end of each module plant,tory burch sale, design drawings based on updated results of the discussions, plans to issue a prim mold, mold technology plans, including the terminal ID brand, BOM and 3D drawings.



Fourth, structural modeling
1. data accumulation
MD begin modeling need ID to provide frames of is under the process ID delineate the contours of the map, and be able to compare a true reflection of ID's design ambitious, the output file can be DXF and IGS format, DXF format if it is, MD take a different viewpoint in the frame at six in the CAD view of the position gracefully, so that the scanning lines PROE transferred (directly in the PROE rotating frame, but a different view of the trouble.) ID is also responsible in the rhino different perspectives to help MD to wireframe view of the position by six arranged the format saved as IGS, MD just described in the ROE in line on it. One might ask, everything truly is to scan lines, ID frame provided surface is not directly used to draw easier way? No, ID is not obtainable parameters of the frame can not be modified and edited, restricted follow-up structural adjustment, so I do not recommend MD to provide the frame directly by ID . but also directly to the ID does not scan lines JPG picture, so to describe his line of MD, it is more chaotic, picture zoom ratio between the length and width may change, MD specification of the line may have a larger ID of the design intent different, and so is not recommended ID does not scan lines directly to JPG images.
rhinoceros if there is to do with the phone ID reference surface the better, in fact, ID also can be modeled, and the degrees of emancipation than the PROE large rhinoceros, so ID MD faster than the speed of modeling, only ID on the drag mode and dismantled touch absence of perception may be out of the surface and the tangible construction is slightly different, the structural design of the follow-up of little assist, only accustom for reference.
Also, if there is a duplicate edition of the prototype to provide a reference, or can be base online ready-made images, which can provide convenience for the MD modeling. motherboard already has the 3D is the MD, to be used directly to find out, but, with the best and the ID before the check anew to see if there is no get wrong, there did not receive the updated version, or other structure, may not finish the plate only to find pain.
2. the idea of ​​dismantling
MD hands well before the first phone to how the demolition of parts, make phone has one important idea, that is, the phone must have one of the main shell, the main strength is the best thickness is thick, the whole strength of thanks to him, to pay the other parts are accompanied to him, so that the structure was strong and mobile, is relying on the fixed board in the main, if appropriate for the thick shell body, usually the motherboard installed in the shell, thick shell suitable if the next body, usually the motherboard installed in the next shell,
dismantled seek simple, also massive too radiated intensity will decrease mobile phone, the assembly will amplify the hardship of Great, if I were you, discuss the balance and structure of some colleagues, and aspire to detect the best program of dismantling. dismantled the program after setting, we must consider the Draft between each shell, and up and down forward the mold shell to 3 degrees above, metal decorative pieces around the mold to pull more than 5 degrees.
3. the appearance of surface rendering
appearance side is the contour of the phone side, a nice curve of a good surface, when the scan line have to be near to the ID of the frame, and esteem the inspired ID is a structural engineer elementary exercising. At the same time also to try to flat lines, curvature as even as likely,tory burch sale, to be taken into account Taper angle, whether the ID of the line of Draft angle and structural requirements are incongruous, you can and ID consultation, and whether tiny impact on the exterior can be depicted by the structure contour line instantly to the Draft amendments angle, whether the plastic shell to maintain Taper Angle on the ID of the ingenious erasure of large, may hope to think the four sides of the plastic mold line rank to do, once and for all, is a high-end buyer phone, this investment is worth.
phone number is symmetrical shape, appearance only need to do half of the face, the other half to the back of the mirror to do again when dismantling the elapse, the finished appearance of the surface before their check and draft to smooth the situation, and then establish the assembly diagram, the Omo and the motherboard together, look at the basic size is adequate, and finally you come and see meet ID does not meet the design requirements, ID confirm the complete dismantling of the can.
4. preparatory dismantled
This time the split pieces is made to the customer look and confirmed by the appearance of palm, and can not do hollowing, but the appearance of the parts can be seen to be drawn into a single, easy look to do different surfaces Push, the appearance of the surface of a rounded corner on the place to lead, the hand, can not be disregarded. general assembly drawings of parts are labeled and delivery requirements, such as button is for button factory to do, can converge on one makeup, the purchase and investment in the form of a component model can be sent out, it is convenient.
5 . modeling data output
MD modeling is completed, the machine PROE 6 drawings in the production of view, dump the document back to DXF wireframe adjustment process ID label, complete construction of six-view mode with the original frame may be provided to the MD of the frame ID are modified, ID needs to do the appropriate update, and beyond complete the process graph indicating the manifold components of the material and visual appearance of the surface process, screen publishing or laser engraving is even a film information, updated information on the process Tufei Lin, together with MD modeling 3D map can be issued to make the appearance of a palm.
plastic decorative surface effects can be done, hurling, metal sense of the advantage of strong, high quality, good wear resistance, plastic decorations direct hot glue or buckle in the shell, the thickness 0.9 ~ 1.0mm, IML piece is a silk screen pattern FILM has been placed in plastic molds for injection molding, this FILM can be divided into three layers: the substrate (usually PET) , INK (inks), wear-resistant materials, injection molding is completed, FILM and plastic integrated, wear-resistant material in the external membrane of plastic material which mostly PC, PMMA, there is the role of wear and resistance to scratching, the surface hardness up to 3H. IML hot glue or deduction items directly in the shell, the thickness of at least 1.2mm.
Nickel-metal decorative pieces in the film is the maximum commonly used, beautiful appearance, thin tweezers thickness 0.1 ~ 0.15mm, mold can not do better mesh diameter as small as 0.3mm. If treads are necessary to mold the system to do kneeling, the overall thickness of no more than 3mm, the side pull level mode is greater than 10 degrees.
aluminum trim thickness 0.4 ~ 0.5mm, because the soft, brushed surface made of ruled, chaotic pattern, ripple, swirl marks and so on. Anodizing is also called corrosion treatment, is the current role of the metal surface formed by a layer of oxide film, wealthy colors, beautiful color, good electrical insulation and hard wear, corrosion resistance is quite high. Sand blasting is to be decorative or fine film optical reflector surface to meet the soft gloss, and other special design needs. After the processing of optical processing are high in aluminum ramp edge milling out a bright side, the same shape as lead C angle. thickness of stainless steel decorative pieces
0.2 ~ 0.3mm, high hardness than aluminum neat, the previous single color, but with the technology now color has been gradually enriched. Other pieces of stainless steel decorative effect of the main drawing surface treatment, high light (mechanical lustering), Ma surface (sand), matt, etc..
17.
the structural design of the battery carton compartment phone battery energy arsenal place, requiring the battery effortless to load, good contact, do not turn dropped out, simple to take, the structure of the battery box must encounter these requirements,
a. battery box as the basic material thickness 1.0mm, the bottom of the battery case as closed, there are components to avoid component, no component plastic shell covered with as much as possible, to avoid exposing large areas of the PCB.
b. gap, elect and place the instruction of unilateral gap 0.2mm, Taper 3 to 5 degrees, the direction of the unilateral unlock of non-access gap 0.1mm, Taper 1 to 2 degrees. battery and battery box at the bottom of the gap is 0.1mm. Battery Cut the bottom of plastic containers and plastic shell gap chip components remain 0.2mm, the bottom of the battery box rubber and plastic shell dig the gap left SIM card connector 0.5mm.
; c. the direction of two pick and place the battery needs to be done with the buckle and the battery, to prevent loosening of anchoring the amount of the battery can take place according to the simulation to assess the time of rotation. pull the hand position to set aside slightly wider than the nails pits, easy finger cutting out the battery
d. battery box to protect the battery connector, battery into the battery box that can only touch upon shrapnel to the battery connector, and not granted way to the battery connector body, so as not to drop test the impact of causing mar to the battery connector.
18. motor
motor design is a weak mechanical vibration on the mobile phone electronic components, when the consumer speechless, via the motor's vibration sensor allows the user to cry the motor is divided into cylindrical and flat fashions, connections are wire-type, shrapnel-type, there are SMT type and plug-in.
cable type, shrapnel-and plug-like cylindrical body outside of the motor is usually set in a rubber sleeve, we just played around in the shell of bone wrap rubber sleeve on it, bone and rubber sleeve around the gap between the zero Bone conduction angle around the top reserve to facilitate the motor climb. careful to depart enough for the eccentric circulation space, an blank shell to avoid eccentric rotation range of at least 0.5mm.
flat rubber sleeve with no motor, side pressure on the board, the other side of the direct use of double-sided adhesive on the housing, from around 2 / 3 of the bone can circle around, you might inquire Why bone to stay around 1 / 3 of the gap? the original structural design not only to consider the assembly and authentic, also easy to remove should also be considered. With 1 / 3 of the gap, the removal of a lever the tweezers when the motor can, incidentally one, flip phone magnet positioning sensor on the bone to stay around 1 / 3 of the gap, but also the same reason. flat motors can also be fixed on the antenna bracket on the side of the bracket with double-sided adhesive on the antenna, antenna stand around from 2 / 3 laps around bone, the other side of the bone with a shell length of rubber hold him down, pay attention to inhibit bone glue can not be head-on motor, rubber bone and a 0.3 motor wind gap between, affixed to a layer of foam about buffer to protect the motor.
19.
the structural design of the stylus pen only in the mobile phone with touch screen only used in general fixed in the next shell, use pull out the stylus into the cap, the pen tube and pen, hanging pen cap on the need to do, to do with a pen hanging points to pull the hand of the dial to facilitate the pumping out pen, pen tube is hollow stainless steel or copper, can be made as needed with one or more section of the elongated section. nib with a round groove, the groove by inserting after the positioning under the shell,
; 20.
the structural design of the battery cover the battery, SIM card and T-FLASH card should be designed to be replaced, hid them in the next shell of the battery box, and then design an easy to open and close the battery cover protected them, the battery cover material can be plastic parts, the surface can be affixed to decorative parts such as lenses or metal films and so on can also use stainless steel sheet bending shape, the structure including the battery cover pull the hand position, buckle, side buttons, call points, pull the battery cover hand positions when the force is to take place, buckle, side buckle is the battery cover, insert the following shell structure when the bite, call point is inserted under the battery cover to prevent the exit after the lock shell structure.
21. wear Design
rope hole is a hole through the phone cable to the structure of fixed ropes, lightweight phone that can wear a breast belt hanging before, but now with the surface of metal decorative pieces of mobile phones increased, and long standby battery resulting increase in volume, have made the gradual increase in the heaviness of the phone itself, there are also no longer require customers to do a lanyard hole. Anyway, I do not suggest all the phone hung on the chest, in addition to the security context does not allow here, the mobile phone battery insecurity gradually speed up human are cared about, or hides it in his pocket!
hole through the structure of cord generally do in the next shell,壮志凌云，倒霉催的小jeep, use the gap at the antenna bracket see every pin, row position is indispensable, but also cage the lanyard to ensure adequate strength of bone bits.
X. Push the structure in front of the structure of the confirm done then
Well, just on periodical, needs the help of physical design verification, structural Push to verify the structure played a role, so the structure of information, including ID Technology Push mark, BOM and 3D picture (of course, be referred to as STP format) , the structure needs Shouban making about 4 days, the appearance and size are persistent with the requirements and drawings, which is close to the final prototype, coupled with the motherboard and get the structure of palm power cell, which is a real phone, do not be too merry early, carefully check the part size, look at the overall assembly has no problem, there is not improvement can make making more efficient and convenient, and now more careful in the hereafter to a smooth point of the mold.
one program to determine
motherboard design company in the phone, usually divided into the marketing department (hereinafter referred to MKT), Department of shape design (hereinafter referred to as ID) , Structural Design Department (hereinafter referred to as MD). A mobile phone project is a piece of board from the designated beginning, the needs of our customers choose the right according to the market the motherboard, where to get a motherboard from a solutions company, 3D map, find a style of design company Design the shape and structure. Customers also find the design company to design directly current motherboard design, which requires phone companies to structural engineers and program to do according to customer requirements pile new motherboard, and then do follow-up, not to introduce here. When designing the company signed an concert MKT and customers, to get customers to the motherboard, 3D map, the project was officially launched, MD's work began.



Fifth, the appearance of palm production and appearance of the Hand of the system to adapt the appearance
do have a special hand-mill, and making a jellybean bar handset 3 to 4 days, the appearance of the plate is solid. can not be removed, mainly used to validation the appearance to the customer, and now look at the bottom Push the button pad can be litter-chip, with the feel, the same as the real machine. customers receive after the assessment, given modifications, MD is responsible for improvement, you can start the internal structure.

; six
structure refinement chart the overall layout should begin start, I suggest that the structure of the premier to do the overall maneuvering, which is apt do up and down shell merely lines, columns and chief buckle screw structure, finish this trilogy, the phone to create up the framework. then emulate from altitude to bottom, and area the order from top to complete details of the structure and so, at above to the afterward is done aboard the 1st shell components, shell components do next, from the top and to the housing assembly is in the mandate they do along to the handset from the base of the top of the MIC, which is the whole idea , characteristic to the local array can too do some adjustments to account as the situation of such relatively large shade, I can do first screen, the additional in order to do down. Please memorandum namely every elaborate of the structure of a complete do it for much as the afterward detail, not to the back of the retard and optimize the annexed workload.
1.
Mouth of the production line ; interior structure began with the pumping of the upper and lower crust shell, generally take the basic wall thickness 1.5 ~ 1.8mm. zero clearance between the upper and lower case, as I said before how to determine the subject, suitable as the main petticoat thick only the mouth, the other is made public only a mouth, only I should not be too deep, and generally 0.6mm enough, for the convenience of assembly, may be appropriate to make public only the mouth or lead Taper Angle C angle.
; 2. screw screw columns
column is to determine the structure of the strength of the key machine, usually on the motherboard will Column reserved for the six screws holes, do not garbage as many as possible make use of them. screw column is also an important role in the fixed motherboard, motherboard installed in which case, a corresponding screw column some changes in practice, not only screw column and the board to mate pipe holes on the live board, screw the side column caught the motherboard to be done to strengthen tendons, so that the structure was solid.
3. the main button layout
4. decorative metal piece on the shell structure of
fixed decorative metal piece on the shell usually made of stainless steel sheet or aluminum, the thickness of 0.4mm or 0.5mm, with a thermal plastic, double-sided tape or buckle-bit fixed, the surface can be brushed, electroplating and laser engraving. which can be surface rusted aluminum into a diversity of different colors, you can cut out the brim of the shine side.
5.
fixed structure screen screen as if the phone's face, to take good care of them, build the wall? right, is to use a circle around a long bone on the shell up, hang on until the board has (left 0.1mm gap ), the LCD closed, even if the subject is the impact of external oppression on the shell around the bone, because bone around screen higher than the Well. screen positive can not be in straight contact with the shell, head-on screen will be crushed, must screen 0.5mm thick paste around the front of the foam, the foam is ziped thickness of 0.3mm, so the screen on the front and put the gap between the upper shell of 0.3mm. in front of the calculation of the thickness of said machine, where you We look at the front part of the thickness of the screen how the calculation.
order to assist the loading screen,tory burch sale, we will join guide around the top of the bone angle, of course, if there are units around the screen or to lest the partly cutback paste, put the gap at fewest 0.2mm, if it is connected with the motherboard screen avoidance FPC, FPC bone and the gap is around 1.0 or more to do.
6. handset
fixed structure is a mobile phone handset sound apparatus, usually the top of the screen Department, in appending to positioning, it also needs to have good sound chamber sealed, the structure surrounded by a circle on the shell of bone surrounded the handset from the outside, and the bone around screen similar to bone but do not hold the handset to the main embark around, wrap handset thickness of 2 / 3 would be sufficient. and then renovated on the shell of bone surrounded by a surround around the sound hole handset, built around a affirmative bone compression of the foam earpiece, surrounded by a relatively closed sound compartment, and finally in the final shell out the sound hole on the line, a sound hole on the shell should be in the range of the handset among the sound hole.
From the appearance, location of the handset the sound hole will do some simple elaboration, such as the cover sheet of a nickel mesh, can also be a decorative piece of plastic plated with dust network use, attention to decorative pieces of plastic commonly used iron plastic column means fixed, dust screen is attached to the earpiece sound chamber inside,
7. before the camera fixed structure
; before the board at the front of the camera, the use of PFC, connector and motherboard. by positioning the camera from the upper shell of bone around wrap around cameras to positioning. the eyes of the camera like a mobile phone in order to ensure good shooting, the camera lens front part of the structure need to have a good seal to prevent dust or foreign matter into the blocked line of sight,tory burch sale, and we help of the lens and case foam separates the interior part of the outside is stamped with a perspicuous lens, in order to ensure good representation and wear light, camera lens glass material, the bottom of the screen printing, screen typography is intended to cover the lens with the shell double-sided adhesive tape between the body,
is worth mentioning that the camera lens assembly is in the final stages of assembly machine do the , co-shell locking machine screws after achievement, use a clean wind blowing pistol shots carefully, before the lens connected to the housing through the double-sided adhesive, and cover the lens.
8. power-saving mode
fixed structure of the lens with the lens than the less power-saving mode, power saving mode on some phones set, need to open a skylight on the cell phone shell, so there's photographic ID to sense the brightness of the outside world, which requires prologue the case and stamped on the lenses, the lens sheet can be tear with a PC attached to the chassis directly to the outside can also be made of a light beam guided injection molded plastic hot inside the enclosure fixed.
9.MIC
fixed structure ; MIC in the bottom of the phone, wanted, favor the ear phones is to alter the sound into electrical whistles external components, so let the voice of the outdoor earth pass without prevention MIC when also preventing the voice of the crater inside the case affects the MIC, the structure is indispensable from the circuit of the bone, while MIC itself to be mantled packets, only reveal a small hole in front of the sound sensor, front must also be a good eligible with the shell, the shell routinely opens on the lead hole on the hole 1.0mm.
MIC linkage with the motherboard can be a wire, soldering welding FPC or dress on the motherboard.
; 10.
the structural design of the main key mobile phone keypad according to the thickness of the main points can be divided into svelte buttons and conventional buttons, flip done before machines, when the slide machine because the thickness of constraints of space with the thickness of 2mm opener is not to directly use silicone sheet and the structure of svelte canvas iron or PC can be a membrane, in order to ensure between the keys are not interlocked, canvas between the different function keys will be separated with a through-hole (such as the V3 mobile phone is the primary opener to do so), the character of silica in order to get the keys feel good.
straight drive on the market today to the bulk, I P + R keys as an example to talk about the structural design of the main keys to the structural design of the candy bar machine volume is divided into 100, I think that the structural design of key components accounted for 30%, 30% on the shell components, shell components under 40%, showing the magnitude of keys. P + R keys, including Caps Group parts, brackets and silica gel of three parts, and some key components and support in Cap adds a piece of shading between the paper to prevent light displacement between the keys.
; scaffold material thickness is insistent under the keys, you can use PC or ABS plastic injection molding, thickness 0.8-2.0mm; can also use the PC directly punching sheet thickness of 0.5,0.6 or 0.7mm; key thick enough, the bracket materials 0.15mm thick stainless steel sheet, but considering the ESD (static test) when the impact of steel on board, we need to bend the sides of a steel cantilever, and DOME-chip network on-the ground, and buttons or PCB copper foil on the ground conduction, silicon film thickness of 0.3mm, positive long-boss and the Caps with the glue water. on the back stretch film DOME with columns and litter.
; 11.
the structural design of the side buttons buttons in the phone left and right side of the side or top side, function is usually the volume keys, camera key, power key, or lock key, etc. structure is relatively simple primary keys, side button on the motherboard to do with the position usually means wearing a fixed number of lateral welding mechanical key is pressed, a mechanical key corresponds to a function. mechanical side of the key advantages of simple structure , feel good. also have to do FPC buttons, pad locations on the motherboard set aside by way of welding face key board fixed a FPC, FPC, after bending toward the side of the key board, key board chip can sense the touch litter pressure. FPC board side-key advantage is that under the same side of the center keys can require some adjustment.
side button is usually part of the structural design P + R in the form used, and the main buttons do not compare side button key frame, silicone part of the indispensable help to improve the feel Buzhi Yu rigid, Cap with a skirt to prevent more drop out, keycap surface treatment can be a primary color , fuel injection, or plating, the want of LED lights, side buttons do not require light, and seldom do Crystal Cap, usually with concave functions characters engraved on the way to do in Cap.
; side clasp is a fixed enhancement in the side of the button in one ear and out the side, and then use the shell enhancement bone caught, mainly in the overall assembly process to discourage lax buttons, once after co-shell , the gripping part of the side buttons can not furnish whichever efficacy on the basic, the clamping portion with the breach is zero.
12.USB
the structural design of rubber plug USB rubber plug is used to protect the USB connector cover, to facilitate the opening and closing, usually the soft TPE or TPU material, USB stopper is structured into the body , pull the hand position, tongue, positioning column four parts, the color is dark or close to the color of the shell used, USB concave function of temperaments engraved on the body, pull the hand positions can be made out of style or cut a concave type. the tongue part is inserted into USB connector USB stopper to prevent the loose rubber bone, positioning pins USB stopper is fixed to the shell upside down on, can be made outside the plug-type or direct pressure (direct card in the shell between the body).
similar structures on the cell phone also T-FLASH card or SD card in the lid, the lid can be longer make P + R structure,tory burch sale, that body, pull the hand-some with hard plastic substance, while the inside of the mating, fixed part with soft matter, hard plastic substance and soft material bonded attach with glue between.
; 13. screw hole rubber stopper of the structural design of the exposed surface of the phone
screw hat will affect the appearance, must be screw holes covered with rubber plugs. the battery cover screw cap, can do within the asylum. screw hole rubber stopper of the relatively simple structure, mold can be a USB stopper in the same mold, the mold factory by the making, plastic screw holes similar cylindrical plug for convenient and easy to take, you can hollow inner of the screw hole rubber plug and the shell outer surface contour surface to be consistent, as a small diameter (1.0mm diameter than the screw cap can be), if so two screw holes rubber stopper not the same as the external surface, are not interchangeable, you must screw hole rubber stopper of the foolproof groove on the cylindrical surface to discriminate between make. screw hole rubber stopper structure according to the different needs can and screw axis made eccentric, by the time they cover the screw cap on the line.
screws must be used because the machine apart, so in order to verify the phone has not been removed without permission opened, some manufacturers in the battery cover on top of the screw hole to dig out a platform affixed to a snatching, if you want to loosen the screw hole of the screw, you must demolish the fragile paper. posted easy fragmenting of platform must be based on crisp paper size to design, platform shape slightly larger than the fragile paper, position, lower down than the level of the shell to prevent the fingers deliberately touch the fragile paper.
14.
fixed structure of the speaker phone volume is a muscular selling point, which is made more sound chamber speaker tall demand. In addition to the program requires a company to horn its best pitch to the outside speakers need to pay attention to the sound cavity points:
; a. speaker must be closed before the sound chamber. speakers directly with the shell, the speaker must be affixed between the ring and the case closed foam, speakers must use the side of a long circulate around the shell of bone surrounded, gap left side 0.1mm. If the loudspeaker antenna between the bracket and the shell separated, then the speaker and the antenna bracket foam ring must be affixed between the closed and the antenna bracket and the case must be affixed between the foam ring Cotton closed, in short, the sound of the speakers on a sound hole through the shell scatter out.
b. the first sound chamber speaker shall be greater than 1.5mm. horn speaker sound chamber height is positive to the housing wall of the vertical distance, in order to ensure a high enough speaker sound chamber, or even the sound chamber inside the shell thin plastic to dig 0.6mm thick .
c. necessary to achieve the speaker out of the sound hole place of ​​15% of the sound space, the sound hole area is out of the total area of ​​the sound hole and. speaker is the speaker that sounds positive area after the removal of foam the size of the navel part of the speaker's sound chamber altitude of the higher requirements of the sound hole area of ​​the speaker the greater the proportion of the sound area, when the speaker's sound chamber elevation 20 above, the sound hole area can be a sound and speakers and other large area that is 100%. on most cell phones, speakers and sound chamber in the 1.5 ~ 4mm, the sound hole area of ​​the speaker sound out of an area of ​​15% to 20% , sound effects better.
d. the sound hole of the structure of the most simple direction is directly in the shell hole can be circular hole order, it can be a chairman strip the holes. To prevent dust and exotic stuff into the sound chamber, can be affixed to the inside of the shell dust web, to beautiful, the sound hole on the outside can be affixed to nickel plate, PC pieces and other decorative pieces, nickel mesh sheet can be small in diameter to 0.3mm, the situation in the use of nickel plate, the shell can not affixed to the inside of dust web.
; e. tune after speaker mainly affects the low frequency part of the ring, a smaller impact on the high frequency part, you can not do apply. In order to get good bass, components on the motherboard does not interfere with the case and the motherboard can be used with the antenna support, through the foam affixed to the speaker after the formation of closed up after the tune sound chamber. Now in order to get more awesome bass effects, speaker home, there have been shaking speakers, according to the size of the sound speakers can produce different vibration strength of the vibration of the shell passed directly through the user's hands.
; 15. under the shell structure of
fixed camera camera beneath the shell on the shell structure and the firm camera firm structure alike to the use of PFC alternatively connectors are connected to the motherboard, situate the bone absence Wai, sealing foam and lens are required, merely the inconsistency is the positioning of the camera under the shell by method of antenna brackets, antenna assist below the shell circled by camera fixed the sides and bottom of the camera. To ensure the Centre under the shell and the next camera shot shell aperture centre deviation does not happen, the next shell or to the bone nigh positioning. The next shell is finished loading the camera lens neat and mirror after thumping machine dust, and eventually loaded.
16. under the structural design of shell decorations
; next to the plastic shell decorations, IML parts, metal pieces, etc..
second, investment projects during the follow-up
mold plastic parts mold takes 18 days just about, is not the time to do nobody? Of course not,tory burch sale, the mobile phone in addition to plastic parts supplier, there are buttons, metal, mirror, nickel film, batteries, pen, accessories, etc. As long as this phone used, the same can not be less. because these parts of the development cycle shorter than the plastic pieces, plastic pieces we can use this time of mold opening quote, proofing and mold. as keys, hardware die around 14 days time also, some companies have put the plastic pieces, buttons, metal project schedule parallel reach. materials cheaper, you can go to the procurement contract to the mold factory, mold factory before shipping the materials (such as foam, double-sided tape) attached to pay the specified location on the shell, accordingly greatly simplifying the process back the whole assembly.

Second, the design guidelines to get the motherboard production
3D map, ID and can not be called directly, but also the 3D map MD to turn into a motherboard six-view, and think the basic size of machine, which is MD of
basic capabilities, I put it as the company hiring interview questions, there is no independent test done a cell phone will know, even now the wrong respond To be more experienced resume is useless, in fact, the question is very simple, to bring touch screen mobile phone, case in point, such as the length of the motherboard 99, the whole of the length measurement is added 2.5 to each end of the motherboard, the machine length can be achieved 99 +2.5 +2.5 = 104, for example, the length of 37.6 board, the whole breadth of the size that each side of the motherboard with 2.5, the whole width can be 37.6 +2.5 +2.5 = 42.6, such as board thickness of 13.3, the whole the thickness of the size is above the motherboard with 1.2 (including 0.9 and 0.3 on the thickness of the foam shell thickness), coupled with the motherboard beneath 1.1 (including 1.0 and 0.1 the thickness of the battery cover on the battery assembly gap), whole thickness can be 13.3 +1.2 +1.1 = 15.6, the answer is not the only, at a time that means of calculation on the line
ID design appearance also highlighted the need to pay care when the issue, this is a complete design guidelines .
