Golder Finger PCBA Printed Circuit Board los ua ke
Photoplate: Siv thev naus laus zis thev naus laus zis los hloov cov qauv hluav taws xob mus rau lub substrate.Cov khoom siv tooj liab ntau dhau raug tshem tawm los ntawm photomask thiab tshuaj lom neeg etching los tsim cov qauv Circuit Court yam xav tau.Kev kho kub-plated: Kev kho kub-plated yog ua los ntawm cov ntiv tes kub los txhim kho nws cov hluav taws xob conductivity thiab corrosion kuj.Feem ntau, txoj kev electroplating yog siv los ua kom sib npaug ntawm cov khoom siv hlau rau ntawm tus ntiv tes kub.Vuam thiab sib dhos: Weld thiab sib sau ua ke cov khoom thiab PCB pawg thawj coj saib xyuas kom ntseeg tau tias cov pob qij txha ruaj khov thiab txhim khu kev qha.Siv lub tshuab mounting tshuab (SMT) lossis plug-in soldering tshuab, xaiv raws li cov kev cai tshwj xeeb.Kev soj ntsuam zoo thiab kev sim: Kev tshuaj xyuas nruj thiab kev sim yog ua tiav thaum lub sijhawm tsim khoom los xyuas kom meej tias cov ntiv tes kub PCB pawg thawj coj ua tau raws li cov lus qhia thiab cov kev xav tau zoo.
Nrog rau kev tshuaj xyuas qhov muag, kev kuaj tus yam ntxwv hluav taws xob, kev sib cuag impedance test, thiab lwm yam. Kev ntxuav thiab txheej: ntxuav cov Goldfinger PCB tiav kom tshem tawm cov av thiab cov khoom seem.Anti-corrosion txheej kho yog ua raws li qhov yuav tsum tau ua los txhim kho corrosion kuj ntawm PCB board.Ntim thiab xa khoom: ntim cov khoom ua tiav Golden Finger PCB kom tsis txhob muaj kev puas tsuaj rau lub cev lossis kev sib kis.Tom qab ua tiav qhov kev ntsuam xyuas zaum kawg, xa mus rau cov neeg siv khoom raws sijhawm.Goldfinger PCB pawg thawj coj ua txheej txheem yuav tsum muaj kev ua haujlwm siab thiab kev tswj xyuas nruj kom ntseeg tau cov khoom zoo thiab ruaj khov.Peb yuav ua hauj lwm nruj raws li cov txheej txheem saum toj no los muab koj cov khoom zoo zoo golden ntiv tes PCB pawg thawj coj saib.
