Um Alumina (Al2O3)

Qaybaha dhoobada saxda ah ee ay soo saarto Kooxda Wax-soosaarka Caqliga leh ee ZhongHui (ZHHIMG) waxaa laga samayn karaa alaab ceeriin ah oo ceeriin ah oo aad u saafi ah, 92 ~ 97% alumina, 99.5% alumina,> 99.9% alumina, iyo CIP qabow gooni-goosad ah. Sintering heerkulka sare iyo machining sax, sax cabirka of ± 0.001mm, siman ilaa Ra0.1, isticmaal heerkulka ilaa 1600 digrii. Midabada kala duwan ee dhoobada waxaa lagu samayn karaa iyadoo loo eegayo shuruudaha macaamiisha, sida: madow, caddaan, beige, casaan mugdi ah, iwm. loo isticmaalay muddo dheer heerkulka sare, faaruqinta iyo deegaanka gaaska daxalka leh.

Si baaxad leh loogu adeegsado qalabka wax -soo -saarka semiconductor -ka kala duwan: Frames (qaybta dhoobada), Substrate -ka (saldhigga), Gacan/ Buundo (farsameeye),, Qaybaha Farsamada iyo Hawada Hawada dhoobada.

AL2O3

Codsiga dhoobada alumina ee daahirsanaanta sare:
1. Waxaa lagu dabaqay qalabka semiconductor -ka: Chuck vacuum ceramic, disc jarista, disc nadiifinta, dhoobada CHUCK.
2. Qaybaha wareejinta canjeerada: joodarrada gacanta ee canjeelada, cajaladaha goynta canjeerada, cajalladaha nadiifinta canjeelada, koobabka nuugista kormeerka indhaha ee wafer.
3. Warshadaha bandhigga guddi -hoosaad ee LED / LCD: biraha dhoobada, disc shiidi dhoobada, PIN LIFT, tareenka PIN.
4. Isgaarsiinta indhaha, warshadaha qorraxda: tuubooyinka dhoobada, usha dhoobada, shaashadda wareegga daabacaadda xoqidda dhoobada.
5. Qaybaha u adkaysta kulaylka iyo korontada ee dahaarka leh: dhejiska dhoobada.
Waqtigan xaadirka ah, dhoobada dhoobada aluminium waxaa loo qaybin karaa daahir sare iyo dhoobada caadiga ah. Taxanaha dhoobada aluminium -oxide -ka ee daahirka ah waxaa loola jeedaa maaddada dhoobada oo ay ku jiraan in ka badan 99.9% Al₂O₃. Sababtoo ah heerkulka qallafsan ee ah ilaa 1650 - 1990 ° C iyo mowjadda gudbinta ee 1 ~ 6μm, waxaa badanaa lagu farsameeyaa galaas la isku qasay halkii laga samayn lahaa weelka platinum: kaas oo loo adeegsan karo sidii tubbo soodiyam oo ay ugu wacan tahay gudbinta iftiinka iyo iska caabbinta daxalka biraha alkali. Warshadaha elektiroonigga ah, waxaa loo adeegsan karaa sidii wax-ku-celcelinta sare ee wax-ku-oolka ah ee substrate-ka IC. Marka loo eego waxyaabo kala duwan oo ka kooban oksaydhka aluminium, taxanaha dhoobada aluminium ee caadiga ah waxaa loo qaybin karaa 99 dhoobada, 95 dhoobada, 90 dhoobada iyo 85 dhoobada. Mararka qaarkood, dhoobada leh 80% ama 75% of aluminium oxide ayaa sidoo kale loo kala saaraa taxanaha dhoobada oksaydhka aluminium ee caadiga ah. Iyaga dhexdooda, 99 aluminium aluminium ah dhoobada dhoobada ayaa loo isticmaalaa in lagu soo saaro weel heerkulkiisu sarreeyo, tuubo foorno dab-damis ah iyo agabyo u adkaysta dahaarka, sida dhejiska dhoobada, shaabadood dhoobada iyo taargooyinka waalka. 95 dhoobada dhoobada aluminiumka waxaa badanaa loo isticmaalaa sidii qayb adkaysi u leh daxalka u adkaysta. 85 dhoobada ayaa inta badan lagu qaso guryaha qaarkood, taas oo hagaajinaysa waxqabadka korontada iyo xoogga farsamada. Waxay adeegsan kartaa molybdenum, niobium, tantalum iyo shaabadood kale oo bir ah, qaarna waxaa loo isticmaalaa aaladaha faaruqinta korontada.
