Qhov Sib Txawv ntawm Ceramic PCBs thiab Traditional FR4 PCBs
Ua ntej tham txog qhov teeb meem no, cia peb xub nkag siab txog cov PCBs ceramic thiab FR4 PCBs yog dab tsi.
Ceramic Circuit Board yog ib hom circuit board uas ua los ntawm cov khoom siv ceramic, tseem hu ua Ceramic PCB (printed circuit board). Tsis zoo li cov iav fiber reinforced plastic (FR-4) feem ntau, cov ceramic circuit boards siv cov ceramic substrates, uas tuaj yeem muab kev ruaj khov kub dua, lub zog zoo dua, cov khoom dielectric zoo dua, thiab lub neej ntev dua. Ceramic PCBs feem ntau yog siv rau hauv cov circuits kub siab, zaus siab, thiab muaj zog siab, xws li teeb LED, lub zog amplifiers, semiconductor lasers, RF transceivers, sensors, thiab microwave devices.
Circuit Board yog ib yam khoom siv yooj yim rau cov khoom siv hluav taws xob, tseem hu ua PCB lossis printed circuit board. Nws yog ib qho khoom siv rau kev sib sau ua ke cov khoom siv hluav taws xob los ntawm kev luam cov qauv hlau ntawm cov khoom tsis conductive, thiab tom qab ntawd tsim cov kev coj ua los ntawm cov txheej txheem xws li kev xeb tshuaj, tooj liab electrolytic, thiab drilling.
