Substrater af aluminiumnitrid<\/a>\u00a0er en ny generation af h\u00f8jtydende keramiske substrater. Det har h\u00f8j varmeledningsevne (teoretisk v\u00e6rdi er 319w \/ m.k, og den termiske ledningsevne er st\u00f8rre end 140W \/ m.k), lav dielektrisk konstant (8,8) og dielektrisk tab (~ 4) \u00d7 104) og termisk ekspansionskoefficient (4.4 \u00d7 10-4 \/ \u2103), kemisk sammens\u00e6tning Al 65,81%, N 34,19%, specifik tyngdekraft 3,261 g \/ cm3, hvid eller gr\u00e5hvid, enkeltkrystal farvel\u00f8s og gennemsigtig, sublimering og nedbrydningstemperatur af aluminiumnitridsubstrater er 2450 \u2103 ved atmosf\u00e6risk tryk.<\/p>\nAluminiumnitridkeramik har h\u00f8j varmeledningsevne, gode elektriske egenskaber, varmeudvidelseskoefficient t\u00e6t p\u00e5 Si-chip, h\u00f8j styrke, h\u00f8j temperaturbestandighed, kemisk korrosionsbestandighed, h\u00f8j resistivitet, lavt dielektrisk tab og ikke-toksicitet. Aluminiumnitrid er et ideelt materiale til at erstatte BeO-keramik og et ideelt varmeafledningssubstrat og emballagemateriale til integrerede kredsl\u00f8b i stor skala.<\/p>\n
Aluminiumnitridsubstrater bruges hovedsageligt som h\u00f8jtydende substratmaterialer og emballagematerialer i hybridkredsl\u00f8b med h\u00f8j densitet, mikrob\u00f8lgeeffektenheder, effektelektroniske enheder, optoelektroniske komponenter, halvlederk\u00f8ling og andre produkter. Det bruges i vid udstr\u00e6kning i kommunikationsenheder, LED med h\u00f8j lysstyrke, kraftelektroniske enheder og andre industrier.<\/p>","protected":false},"excerpt":{"rendered":"
