Qhov txawv ntawm Ceramic PCBs thiab Traditional FR4 PCBs
Ua ntej sib tham txog qhov teeb meem no, cia peb nkag siab txog dab tsi ceramic PCBs yog dab tsi thiab FR4 PCBs yog dab tsi.
Ceramic Circuit Board yog hais txog ib hom Circuit Court board tsim los ntawm cov khoom siv ceramic, los yog Ceramic PCB (luam Circuit Board). Tsis zoo li cov iav fiber ntau reinforced yas (FR-4) substrates, ceramic circuit boards siv ceramic substrates, uas tuaj yeem muab kev ruaj ntseg kub dua, zoo dua mechanical zog, zoo dielectric zog, thiab ntev lifespan. Ceramic PCBs yog siv nyob rau hauv high-temperature, high-frequency, thiab high-power circuits, xws li LED teeb, lub hwj chim amplifiers, semiconductor lasers, RF transceivers, sensors, thiab microwave.
Circuit Board hais txog cov khoom siv yooj yim rau cov khoom siv hluav taws xob, tseem hu ua PCB lossis luam tawm Circuit Board. Nws yog cov khoom thauj khoom siv rau kev sib sau cov khoom siv hluav taws xob los ntawm kev luam ntawv hlau Circuit Court qauv ntawm cov khoom siv tsis zoo, thiab tom qab ntawd tsim cov kev coj ua los ntawm cov txheej txheem xws li tshuaj lom neeg corrosion, electrolytic tooj liab, thiab drilling.
Cov hauv qab no yog kev sib piv ntawm ceramic CCL thiab FR4 CCL, nrog rau lawv qhov sib txawv, qhov zoo thiab qhov tsis zoo.
