Nyob rau hauv kev tsim cov khoom lag luam hauv cov khoom siv hluav taws xob, PCB (luam tawm cov khoom siv hluav taws xob, thiab nws qhov zoo cuam tshuam cov kev ua tau zoo thiab kev ntseeg tau ntawm cov khoom. Txawm li cas los xij, thaum kev tsim khoom thiab kev siv PCBs, teeb meem xws li kev tawg lossis tej zaum kuj yuav cuam tshuam rau nws qhov kev ua tau hluav taws xob thiab muaj zog.
Vim li cas rau PCB Pawg Thawj Coj
1. Cov teeb meem khoom siv
Cov ntaub ntawv tsis zoo siv nyob rau hauv kev tsim cov pcb Circuit Coffs, lossis kev tsis txaus siab cov ntaub ntawv nthuav tawm ntawm cov khoom siv hluav taws xob hauv hluav taws xob thiab kev sib zog, ua rau PCB pawg thawj coj.
Lub substrate ntawm pcb (xws li ntaub fiberglass impregnated nrog epoxy cob qhia, uas yuav ua rau pcb los tsoo kev ntxhov siab thaum siv.
2. Ib puag ncig cov xwm txheej
Thaum lub sij hawm cia lossis tsheb thauj mus los, yog PCB nthuav dav, nws yuav ua rau muaj kev hloov pauv ntawm lub sijhawm ntev, nws yuav ua rau sab hauv kev ntxhov siab thiab thaum kawg ua rau tawg.
Thaum qhov ntsuas kub hloov tau ntau, cov khoom siv thiab cov khoom siv rau PCB yuav yauv ua kom muaj kev ntxhov siab thiab ua rau cov kab mob PCB kom tawg; Lub voj voog ntawm PCB yog nquag rau noo noo corrosion hauv siab av noo ib puag ncig ib puag ncig, uas tseem tuaj yeem ua rau PCB pab pawg kom tawg.
