Cov txheej txheem ntau lawm ntawm PCB tsis yooj yim, nws yuav tsum tau ntau cov txheej txheem hauv kev tsim khoom los ua tiav cov txheej txheem tsim khoom; Ntawm lawv, lub qhov thiab muab cov txheej txheem plug lub teeb yog ib kauj ruam tseem ceeb hauv PCB tsim cov txheej txheem.
1. Cov lus txhais ntawm kev siv lub qhov rooj
Ntawm hais txog lub qhov uas txuas sib txawv ntawm cov txheej txheem sib txawv, thaum cov ntsaws cov khoom siv corrosion lossis tshuab txiav, kom txo tau qhov kev ua yuam kev ntawm kev sib txawv thiab cov khoom tshwm sim ntawm tsis xws luag xws li luv luv voj voog.
2. Txheej Txheem Flow ntawm mus txog-lub qhov ntsaws lub qhov
2.1 drilling
Thawj kauj ruam ntawm kev plugging txheej txheem yog los tho qhov, siv lub laum me ntsis los tsim cov qhov xav tau ntawm PCB Board. Qhov chaw tso thiab aperture qhov tseeb ntawm kev khiav ncaj qha cuam tshuam qhov zoo thiab kev ntseeg tau ntawm cov txheej txheem tom ntej.
2.2 Txheej
Tom qab kev khiav tawm tiav, lub qhov ntsa yuav tsum tau coated electroplating thiab ntsaws cov txheej txheem. Cov txheej feem ntau siv cov tshuaj depender tso rau lub hau phab ntsa nrog cov tshuaj siv tshuaj lom neeg, tsim cov txheej tiv thaiv.
2.3 electroplating
Cov Hluav Taws Xob yog cov kauj ruam tseem ceeb hauv kev plugging txheej txheem, uas cuam tshuam nrog electroplating sab hauv lub qhov siv cov txheej txheem hluav taws xob uas yuav tsum tau sib txuas. Electroplilcilating tuaj yeem nce qhov kev coj ua ntawm vias, txhim kho lub neej ruaj khov thiab kev pabcuam ntawm PCB cov laug cam.
2.4 Lub Qhov
Tom qab Electroplating tiav, tus muab cov txheej txheem plug lub qhov yog qhov yuav tsum tau ua, uas yog kauj ruam kawg nyob rau hauv lub qhov txheej hloov lub qhov txheej txheem. Lub hom phiaj ntawm plugging qhov yog kom ntseeg tau ntawm aperture ntawm aperture ntawm aperture ntawm aperture ntawm aperture ntawm aperture ntawm aperture ntawm aperture, tshem tawm cov tshwm sim tooj liab, thiab zam dhau qhov tshwm sim ntawm qhov tsis xws luag xws li luv luv hluav taws xob. Muaj ntau txoj hauv kev rau ntsaws lub qhov, xws li tshuaj lom neeg, kho tshuab milling, thiab tungsten hlau txiav thiab cua.
