Kev tsim khoom ntawm PCBs yog ib txwm ua tiav siv cov txheej txheem tshuaj etching. … Feem ntau cov tooj liab ntawm cov ntawv luam tawm liab qab yog npog nrog ib txheej nyias ntawm cov duab tiv thaiv. Tom qab ntawd nws raug pom los ntawm lub teeb los ntawm cov duab thaij duab lossis daim duab daim npog ntsej muag uas qhia txog cov kab uas xav tau.
cov ntawv luam tawm los ntawm qhov twg?
Printed circuit boards (PCBs) feem ntau yog ib lub tiaj laminated composite ua los ntawm tsis yog cov khoom siv substrate nrog cov txheej ntawm tooj liab circuitry faus sab hauv lossis sab nraud.
Puas luam tawm Circuit Boards tseem siv?
Lawv yog ua los ntawm cov khoom siv tsis zoo thiab muaj cov kab, cov ntaub qhwv thiab lwm yam khoom siv los ntawm cov ntawv tooj liab uas txuas hluav taws xob txuas cov khoom siv hluav taws xob hauv cov khoom. … Niaj hnub no, kev siv PCBs hauv hluav taws xob yog dav thiab muaj ntau hom PCBs.
Dab tsi yog qhov tsis zoo ntawm cov ntawv luam tawm hluav taws xob?
