Lub hauv paus ntawm PCB feem ntau yog ib qho uas tsis yog-conductive substrate, xws li fiberglass los yog yas, uas yog overlaid nrog tooj liab txheej los tsim cov qauv conductive.
Cov qauv no tsim cov qauv geometric thiab pab txuas cov khoom siv hluav taws xob hauv txoj hauv kev zoo. PCB muab txhua yam kev txhawb nqa rau cov khoom siv hluav taws xob thaum txo nws qhov loj kom lub cuab yeej tuaj yeem ntsia tau rau hauv ib qho chaw me me. Cov PCB boards no yog qhov tseem ceeb hauv kev tsim ntau yam qauv tsim kom ua tiav ntau yam kev xav tau hauv kev lag luam hluav taws xob.
PCB tuaj nyob rau hauv ntau hom thiab complexity, nrog rau ib leeg-sab, ob-sided, thiab ntau txheej boards. Cov hom PCB ntau dua muaj kev ua haujlwm ntxiv, tso cai rau kev tsim hluav taws xob ntau dua.
