Cov kauj ruam tseem ceeb hauv Flex Circuit Assembly txheej txheem

Flexible circuits tau dhau los ua ib feem tseem ceeb ntawm cov khoom siv hluav taws xob niaj hnub no. Los ntawm cov xov tooj smartphones thiab ntsiav tshuaj mus rau cov cuab yeej kho mob thiab cov cuab yeej siv dav hlau, cov khoom siv hluav taws xob hloov pauv tau dav siv vim lawv lub peev xwm los muab kev ua tau zoo dua qub thaum tso cov qauv tsim thiab hloov tau yooj yim. Txawm li cas los xij, kev tsim cov txheej txheem hloov pauv hloov pauv, hu ua flex circuit sib dhos, muaj ob peb kauj ruam tseem ceeb uas yuav tsum tau ua tib zoo tuav thiab saib xyuas kom meej.Hauv tsab ntawv tshaj tawm no, peb yuav tshawb xyuas cov kauj ruam tseem ceeb uas cuam tshuam nrog flex circuit sib dhos txheej txheem.

1. Tsim layout:

Thawj kauj ruam hauv kev sib dhos flex Circuit Court yog qhov tsim thiab layout theem.Qhov no yog qhov uas lub rooj tsavxwm tsim thiab nws cov khoom tau muab tso rau ntawm nws. Cov txheej txheem yuav tsum ua raws li qhov xav tau thiab qhov loj ntawm qhov kawg flex Circuit Court. Tsim software xws li CAD (Computer Aided Design) yog siv los tsim thiab tswj cov txheej txheem, kom ntseeg tau tias tag nrho cov kev sib txuas tsim nyog thiab cov khoom siv tau suav nrog.

2. Kev xaiv cov khoom siv:

Xaiv cov khoom raug yog qhov tseem ceeb thaum lub sij hawm sib dhos flex Circuit Court.Kev xaiv ntawm cov khoom yog nyob ntawm ntau yam xws li qhov yooj, durability thiab hluav taws xob kev ua tau zoo uas yuav tsum tau muaj rau hauv Circuit Court. Cov khoom siv feem ntau siv hauv kev sib dhos yooj yim xws li polyimide zaj duab xis, tooj liab ntawv ci, thiab cov nplaum. Cov ntaub ntawv no yuav tsum tau muab los ua tib zoo vim tias lawv qhov zoo cuam tshuam ncaj qha rau tag nrho cov kev ua tau zoo thiab kev ntseeg siab ntawm flex circuit.

3. Imaging thiab etching:

Thaum cov qauv tsim thiab xaiv cov khoom tiav, cov kauj ruam tom ntej yog imaging thiab etching.Hauv cov kauj ruam no, cov qauv Circuit Court raug xa mus rau cov ntawv ci tooj liab siv cov txheej txheem photolithography. Cov khoom siv lub teeb-sensitive hu ua photoresist yog coated rau ntawm tooj liab nto thiab cov qauv Circuit Court raug rau nws siv lub teeb ultraviolet. Tom qab kis tau, cov chaw tsis raug tshem tawm los ntawm cov txheej txheem tshuaj etching, tawm hauv cov kab uas xav tau tooj liab.

4. Drilling thiab qauv:

Tom qab cov duab thiab etching cov kauj ruam, lub flex Circuit Court yog drilled thiab qauv.Precision qhov yog drilled ntawm Circuit Court boards rau kev tso kawm ntawm cov khoom thiab interconnects. Cov txheej txheem drilling yuav tsum muaj kev txawj ntse thiab qhov tseeb, vim tias qhov kev sib raug zoo tuaj yeem ua rau muaj kev sib txuas tsis raug lossis kev puas tsuaj rau circuits. Patterning, ntawm qhov tod tes, koom nrog tsim cov txheej txheem hluav taws xob ntxiv thiab cov kab ke siv tib yam duab thiab cov txheej txheem etching.

5. Kev tso kawm thiab soldering:

Kev tso kawm ntawm cov khoom siv yog ib kauj ruam tseem ceeb hauv kev sib dhos flex circuit.Surface Mount Technology (SMT) thiab Los Ntawm Qhov Tshuab Technology (THT) yog ib txoj hauv kev rau kev tso thiab soldering Cheebtsam mus rau flex circuits. SMT koom nrog cov khoom sib txuas ncaj qha mus rau saum npoo ntawm lub rooj tsavxwm, thaum THT suav nrog kev ntxig cov khoom rau hauv qhov tho qhov thiab vuam ntawm sab nraud. Cov tshuab tshwj xeeb yog siv los xyuas kom meej qhov kev tso kawm thiab cov khoom siv zoo tshaj plaws.

6. Kev Ntsuas thiab Kev Tswj Xyuas Zoo:

Thaum cov khoom siv tau soldered mus rau lub flex Circuit Court, kev ntsuam xyuas thiab kev tswj xyuas zoo yog siv.Kev sim ua haujlwm tau ua los xyuas kom meej tias txhua yam khoom siv ua haujlwm zoo thiab tsis muaj qhov qhib lossis luv. Ua ntau yam kev ntsuam xyuas hluav taws xob, xws li kev ntsuas txuas ntxiv thiab kev ntsuas kev tiv thaiv hluav taws xob, txhawm rau txheeb xyuas qhov tseeb ntawm circuits. Tsis tas li ntawd, kev tshuaj xyuas qhov muag yog ua los xyuas seb puas muaj lub cev tsis xws luag lossis txawv txav.

7. Encapsulation thiab encapsulation:

Tom qab dhau qhov yuav tsum tau ua thiab ntsuas kev tswj kom zoo, lub flex Circuit Court tau ntim.Cov txheej txheem encapsulation suav nrog kev siv cov txheej txheem tiv thaiv, feem ntau yog ua los ntawm epoxy lossis polyimide zaj duab xis, rau hauv Circuit Court los tiv thaiv nws los ntawm ya raws, tshuaj, thiab lwm yam khoom sab nraud. Lub voj voog encapsulated yog tom qab ntawd ntim rau hauv daim ntawv xav tau, xws li daim kab xev hloov tau yooj yim lossis cov qauv folded, kom ua tau raws li qhov tshwj xeeb ntawm cov khoom kawg.

Hauv Summary:

Cov txheej txheem flex circuit sib dhos muaj ob peb kauj ruam tseem ceeb uas yog qhov tseem ceeb los xyuas kom meej tias cov khoom siv hluav taws xob zoo tshaj plaws.Los ntawm kev tsim thiab kev teeb tsa mus rau kev ntim khoom thiab ntim khoom, txhua kauj ruam yuav tsum tau ua tib zoo saib xyuas kom meej thiab ua raws li kev tswj hwm nruj. Los ntawm kev ua raws li cov kauj ruam tseem ceeb no, cov tuam ntxhab tuaj yeem tsim cov khoom siv hluav taws xob txhim khu kev qha thiab ua tau zoo uas ua tau raws li qhov xav tau ntawm cov khoom siv hluav taws xob niaj hnub no.
