Tooj liab ntawv ci rau luam tawm cov laug cam (PCB)

Cov ntawv luam tawm cov laug cam (PCB) tau siv dav hauv lub neej txhua hnub, thiab muaj nce ntxiv, cov laug tsheb hauv cov kab ke hauv peb lub neej. Nyob rau tib lub sijhawm, raws li cov kev xav tau rau cov khoom hluav taws xob ua ntau dua thiab siab dua, kev sib koom ua ke ntawm cov laug cam circuit Court tau ua ntau dua. Txhawm rau kom tau raws li cov kev xav tau ntawm cov ntawv thov sib txawv, muaj ntau hom ntawm ib puag ncig cov laug cam, uas imposes cov board ntau dua ntawm cov Circuit Court Board, uas yog CCPPER Laminate (CCL). Ntxim cov hlau tus tooj liab ntawv ci tuaj yeem ua tau raws li txhua yam kev xav tau ntawm CCL uas twb muaj lawm. Cov ntawv ci rau cov ntawv luam tawm hluav taws xob muaj cov khoom conduction zoo tshaj plaws, cov tshuaj zoo, cov tshuaj tsis kam, thiab yooj yim etching. Lub caij no, txhawm rau kom tau raws li cov kev xav tau ntawm cov neeg siv khoom sib txawv, kev siv cab tuaj yeem txiav cov nqi luam ntawv ntau ntxiv rau cov neeg siv khoom.
