Cov txheej txheem ntawm Circuit Court board tsim qauv thiab tsim yog qhov tseem ceeb rau cov tshuab hluav taws xob thiab cov chaw tsim khoom. Tus qauv tsim thiab tsim cov rooj tog Circuit Court xav tau qee cov kev paub txog kev tshaj lij thiab thiab cov txheej txheem tseem ceeb ntawm cov txheej txheem no yog PCB piv txwv.
Ua ntej tshaj plaws, cia peb piav lub ntsiab lus ntawm "PCB". PCB yog cov lus luv rau "luam tawm cov board board", tseem hu ua tus txheej txheem Circuit Court. Ib puag ncig cov hluav taws xob yog lub hauv paus siv los txuas cov hluav taws xob hluav taws xob thiab cov voj voog hauv cov khoom siv hluav taws xob. PCB yog tsim ntawm ib lossis ntau txheej txheej ntawm cov ntaub nyias nyias iav (laminate) thiab tooj liab tau tsim nyob rau saum npoo los ntawm kev txhim kho tshuab hauv cov khaubncaws sab nraud. PF Cov Nyiaj Pab Dawb Tso Cai yog feem ntau siv los ua kom nws ua tau. Muaj qee kis, cov hluav taws xob hauv hluav taws xob ntawm cov Circuit Court Board tej zaum yuav soldered rau hauv nws; Kev tsim cov PCB yuav tsum tau tsim thawj lub voj voog rau hauv CAD tsim software, thiab tom qab ntawd upload nrog Circuit Cous tsim chaw tsim khoom lag luam.
Cov theem kawg ntawm Circuit Court txoj kev txhim kho yog PCB kuaj, thaum peb xav tau xaiv PCB cov chaw tsim qauv.
Yog li, pcb sampling yog li cas? Peb txiav txim siab PCB prototyping uas yog kev tsim khoom ua ntej ua ntej rau cov kev tsim hluav taws xob tsim, theem kev txhim kho. Qhov no txhais tau tias ua ntej pawg ntau lawm, cov kev tsim qauv thiab cov pab pawg tsim kev tsim khoom hauv Circuit Court Board kom ntseeg tau tias nws ua tau zoo thiab ua tau zoo. Qhov ua tau zoo thiab kev ua tau zoo ntawm cov khw muag khoom siv hluav taws xob txiav txim siab qhov kev ua tau zoo tag nrho thiab cov khoom siv zoo. PCB piv txwv tseem yog tus txheej txheem los xyuas kom meej qhov tseeb thiab kev ncaj ncees ntawm Circuit Court board tsim qauv. Yog hais tias lub Circuit Court board sampling yog muaj kev vam meej, cov chaw tsim khoom yuav muaj peev xwm txuas ntxiv ua cov khw muag khoom zoo, kom ua tau zoo thiab ua tau zoo ntawm tag nrho cov khoom siv.
Yog li, dab tsi yog qhov zoo ntawm PCB piv txwv? Firstly, los ntawm kev ua qauv PCB, pab pawg tuaj yeem txheeb xyuas cov teeb meem tsim thiab hais txog qee cov teeb meem tshwm sim uas yuav tshwm sim thaum chaw tsim khoom. Qhov thib ob, los ntawm kev sim pcb
