Yog tias koj koom nrog hauv lub ntiaj teb ntawm cov khoom siv hluav taws xob, kev sib txuas lus khoom siv, lossis kev tsim hluav taws xob hauv Circuit Court, nws yog ib qho tseem ceeb heev kom nkag siab qhov txawv ntawm PCBA thiab PCB. Qhov kev paub no tsis yog nthuav xwb; nws cuam tshuam ncaj qha rau koj lub peev xwm los xaiv cov ntawv luam tawm kom raug rau koj cov kev xav tau tshwj xeeb.
1. Nws yog ib qho tseem ceeb kom paub tias lawv tuaj nyob rau hauv ntau hom, dictated feem ntau los ntawm cov khoom siv rau lawv cov substrate los yog hauv paus. Muaj hlau-raws li PCBs, paub txog lawv robustness thiab durability. Ceramic-raws li PCBs, khoom plig rau lawv cov tsis kam mus rau qhov kub thiab txias thiab kev ua haujlwm siab, thiab FR4 PCBs, ua los ntawm iav-reinforced epoxy laminate khoom, feem ntau siv rau lawv cov khoom zoo insulating thiab tus nqi qis.
2. Ntxiv nrog rau kev xaiv cov khoom siv, PCBs kuj tuaj yeem sib txawv ntawm qhov yooj yim thiab cov txheej txheem uas lawv muaj. Qhov kev hloov pauv no yog qhov yooj yim rau cov khoom siv uas tuaj nrog cov qauv tsim tsis zoo lossis qhov chaw nruj. Hloov pauv, muaj cov kab hluav taws xob nruj uas sawv tawm rau lawv lub zog thiab kev ua haujlwm ntev, ua rau lawv xaiv zoo tshaj plaws uas cov khoom siv dag zog tseem ceeb tshaj plaws.
3. Circuit Court boards tuaj yeem ua tau ob hom: ib txheej (ib qho khoom siv hluav taws xob ib sab) lossis ob txheej txheej (ob npaug ntawm cov khoom siv hluav taws xob). Kev txiav txim siab ntawm ob feem ntau yog nyob ntawm qhov tsis sib xws thiab cov kev xav tau tshwj xeeb ntawm cov khoom siv hluav taws xob tau tsim.
