PCB Uyilo lweentambo luchaphazela umgangatho webhodi ye-PCB, kwinkqubo yoyilo yebhodi ye-PCB, hayi kuphela ukuthathela ingqalelo imigaqo-siseko, kodwa kunye nemitha yombane kunye nokwaliwa kokuphazamiseka njengemigangatho esisiseko, uyilo oluneenkcukacha. Abaqulunqi banokwenza ucoceko olusengqiqweni lokuphucula umgangatho woyilo lwebhodi yesekethe.

Uhlalutyo lwesisombululo sokuphazamiseka kuthotho phakathi kweentambo zePCB

Abaqulunqi kwintambo, kufuneka baqwalasele ukuba iziphazamiso zokuphazanyiswa kombane phakathi komqhubi kufuneka zishiye umgama omde ofinyeziweyo, ukunqanda kuya kufakwa kwiintlobo ezahlukeneyo zonxibelelwano ngocingo, kulula ukwenza ukuphazamisa phakathi kwesidingo sokubeka umgca wokushicilela womqhubi womhlaba, umgca phakathi koluhlu lokuphazamisa, unokuba nefuthe elihle kakhulu kuthintelo omnye komnye.

Ii. Uyilo lomgca wePCB ububanzi nohlalutyo

Ixabiso langoku limisela ububanzi be-PCB, ekwagqitywa kukudityaniswa kwe-substrate yokwambathisa. Ububanzi bomgca we-PCB we-2A wangoku ngokubanzi yi-1 ~ 3mm kwaye ubukhulu be-0.05mm.

Iii. Uyilo kunye nohlalutyo lweenkcukacha zomgca wePCB

Ingqwalaselo eyodwa kufuneka ihlawulwe kuyilo lobume bomgca we-PCB kwindawo yokujika. Ngokubanzi thatha iarc setyhula. Isizathu kukuba imilo yoxande iya kwenza umsebenzi wombane kwisekethe ifuthe elingeyomfuneko, ngakumbi kwisekethe ephezulu yokuhamba rhoqo, le mpembelelo iya kuba mbi ngakumbi. Ingqwalaselo eyodwa kufuneka ihlawulwe kukhetho lwezixhobo zemigca ye-PCB. Ngokubanzi, ifoyile yobhedu ngakumbi kufuneka ithintelwe, kuba ukufudumeza ifoyile yobhedu ixesha elide kuya kuyibangela ukuba iwe, ebangele ingozi.
