Muaj ntau ntau qhov zoo rauIMICICH KUB KUB KUB KUB KUB PRINCTED Circuit Court Board, xws li muaj kev ncaj ncees, kev ua neej ntev, siab thiab ib puag ncig ua phooj ywg. Yog li, dua li yog kim, muaj lwm yam tsis zoo?
1. Qhov nyuaj ntawm cov txheej txheem kub yog qhov siab:
Cov txheej txheem kub kub cuam tshuam nrog cov tshuaj lom neeg nyuaj heev xws li kev tsim kho plating, thiab sijhawm yuav tsum muaj kev ua haujlwm siab rau PCB cov tuam ntxhab.
2. Hauv qee qhov siab - kub lossis cov khoom siv muaj zog lossis muaj zog ntawm cov ntaub ntawv impregnegation kub yuav txo qis, cuam tshuam rau lawv txoj kev cia siab ntev.
3. Tsis tuaj yeem ua haujlwm dua: Tsis zoo li cov cua kub kub soldering leveling, immersion hauv kub tsis tuaj yeem ua haujlwm tsis tau.
Lub vuam ntawm immersion gold prined Circuit Court board yog ua tiav los ntawm kev siv tshuaj lom neeg ntawm Nickel kub. Txoj kev vuam vuam no txawv ntawm cov huab cua kub ib txwm muaj kom ua tiav cov tiaj tiaj. Cov txheej txheem vuam ntawm kev nkag siab kub tshiab cov ntawv luam tawm hluav taws xob board yog irreversible. Thaum lub vuam ua tiav, cov ntsiab lus vuam yuav dhau los ua tuab thiab tsis tuaj yeem muab welded dua. Qhov no yuav cuam tshuam ntau ntau thiab hloov tau.
