Beryllia Ceramic SubstrateKev piav qhia
Beryllium oxide (BeO), feem ntau hu ua beryllia, muaj kev sib xyaw ua ke ntawm thermal, dielectric, thiab cov khoom siv tshuab uas xav tau hauv kev siv hluav taws xob. Tsis muaj lwm yam khoom uas qhia txog cov yam ntxwv no. BeO ceramic ua cua sov zoo dua li cov hlau feem ntau, nthuav tawm cov yam ntxwv tsis tshua muaj hluav taws xob tsis zoo, muaj hluav taws xob tiv taus siab, thiab muaj zog zoo heev. Nws muab tag nrho cov txiaj ntsig ntawm lub cev thiab dielectric yam ntxwv uas pom los ntawm txhuas oxide thiab, ntxiv rau, muaj cov thermal conductivity ntau dua thiab qis dua dielectric tas li.
Beryllium oxide ceramic substrates muaj cov yam ntxwv ntawm cov thermal conductivity, siab melting, lub zog, siab rwb thaiv tsev, tsis tshua muaj dielectric tsis tu ncua, tsis tshua muaj dielectric poob thiab zoo ntim txheej txheem adaptability. Lawv tau siv dav hauv kev lag luam microwave, hluav taws xob nqus tsev, nuclear, micro electronics thiab optoelectronics.
