PCB qhov rai qhib yog txheej txheem tshwj xeeb ntawm kev sib sau cov Circuit Court Board hauv Pcb Board. Nyob rau hauv cov txheej txheem ntau lawm ntawm PCB cov laug cam, etching yuav tsum tau nqa tawm ntawm cov kab ke ntawm Circuit Court uas yuav tsum tau qhib, uas yuav tsum tau siv cov thev naus laus zis qhib thev naus laus zis. PCB qhov rai qhib tau tuaj yeem to taub raws li kev ua yeeb yam, uas tuaj yeem sau cov lus sib txuas ntawm Pcb Board thiab yog qhov tseem ceeb hauv ntau lub sijhawm.
Lub hauv paus ntsiab lus ntawm PCB qhov rai qhib yog los npog thaj chaw sab nraum cov chaw uas yuav tsum muaj, thiab khij cov chaw no kom raug. Cov chaw no yuav tsis muaj etched, thiab cov chaw seem yog qhov uas yuav tsum tau qhib. PCB qhov rai qhib tuaj yeem ua tiav siv cov cuab yeej sib txawv, thiab siv ultraviolet hluav taws xob kom muaj thaj chaw sab nraud kom dhau mus. Nyob rau hauv txoj kev no, cov qauv uas tuaj yeem coj kev etching tshwm sim rau tus PCB pawg thawj coj kom ua tiav qhov kev tshwm sim zaum kawg.
PCB qhov rai muaj cov ntawv thov tseem ceeb heev hauv kev ua tau kev sib txuas nrog ntau txheej ntawm cov laug cam hluav taws xob.Zov Theem PCBLub qhov rais tuaj yeem txuas rau lub voj voog ntawm ob lub PCB cov laug cam, yog li ua tiav lub hom phiaj ntawm kev sib txuas sib txawv txheej. Lub caij no, hauv cov txheej txheem ntau lawm ntawm PCB cov camkas los ua kom tiv thaiv cov ntawv txheeb xyuas tooj liab tuaj yeem ua rau lub sijhawm tooj liab.
Thaum ua cov laug cam Circuit Court, PCB Windows muaj lwm daim ntawv thov, uas yog kom ua tiav kev sib cuam tshuam ntawm cov hluav taws xob hluav taws xob sib txawv. Qhov no feem ntau tshwm sim thaum tsim qauv siab PCB cov laug cam, uas qhov kev ncua deb ntawm kev qhib pcb Windows txhawm rau cov kev qhia tshwj xeeb.
Txhawm rau muab cov ntsiab lus, PCB lub qhov rais qhib yog qhov txheej txheem tseem ceeb hauv kev sib txuas thiab chaw tsim khoom PCB cov laug cam. Los ntawm kev tshwj xeeb txheej txheem etching, sib txuas ntawm cov khaubncaws sab nraud povtseg sib txawv thiab cov khoom siv oxidation, thaum ua tiav kev kho mob tooj liab, thiab ua tiav kev txij nkawm ntev ntawm cov tsheb ua haujlwm ntev.
