1. Drilling yog siv rau cov ntaub qhwv thiab cov nplaim taws sib dhos, txhim kho cov hluav taws xob thiab cov thom khwm. Los ntawm Drilling, qhov haum rau ntau yam phab ntsa lossis cov txuas yog tsim nyob rau ntawm cov xaimcb, kom cov khoom siv tuaj yeem ruaj khov rau ntawm cov PCB Board rau kev txuas thiab Intercocunication.
2. Tom qab lub koom haum multilayer yog kom yooj yim txuas cov txheej txheem sib txawv, thiab nce cov teeb meem hluav taws xob ntawm cov kab hluav taws xob sib xyaw los ntawm cov kab mob PCB los tiv thaiv cov khoom sib txawv thiab ua kom cov khoom siv ua kom puas tsuaj.
3. Drilling tuaj yeem siv los kho tus pcb board. Hauv qee kis, PCB pawg thawj coj yog tsau los ntawm cov nkhaus lossis screws los ntawm cov qhov dr drilling thiab ruaj khov.
4. Lub qhov me me ntawm PCB Board yog vias, uas tau siv los txuas cov cim hluav taws xob ntawm txheej sib txawv mus rau lwm txheej. Feem ntau ntawm cov qhov no yog tsim rau cov chaw loj tooj liab, nrog lub qhov ntawm ob tog intercommunication, thiab cov chaw tooj liab liab tau siv rau cov dej ntws loj. Lub hom phiaj yog txhawm rau txhawm rau ua kom sov. Muab ob npaug rau txheej loj-thaj chaw tooj liab tuaj yeem drilling ntau zaus, uas tuaj yeem txo cov suab nrov thiab tsis muaj suab nrov warcing deformation.
