Dulmarka BF33 Glass Wafer
Waferka dhalada ah ee BF33, oo caalami ahaan lagu aqoonsaday magaca ganacsiga BOROFLOAT 33, waa galaas sabbaynaya borosilicate oo heerkiisu sarreeyo oo ay farsamaysay SCHOTT iyadoo adeegsanaysa hab wax-soo-saar microfloat ah oo khaas ah. Habka wax-soo-saarkani waxa uu keenaa xaashiyo dhalada ah oo leh dhumuc gaar ah oo isku mid ah, dhul siman oo aad u fiican, qallafsanaan yar, iyo hufnaan muuqaaleed oo heer sare ah.
Tilmaamaha muhiimka ah ee lagu garto BF33 waa isku-dhafka hoose ee ballaarinta kulaylka (CTE) ee ku dhawaad 3.3 × 10-6 K-1, taas oo ka dhigaysa mid ku habboon silikoon substrates. Hantidan waxa ay awood u siinaysaa is dhexgalka ka xorta ah werwerka ee microelectronics, MEMS, iyo aaladaha indhaha.
Maaddada Waferka ee BF33
BF33 waxaa iska leh qoyska dhalada borosilicate waxayna ka kooban tahay wax ka badan80% silica (SiO2), oo ay weheliso boron oxide (B2O3), oxides alkali, iyo qiyaasta aluminium oxide. Habkani waxa uu bixiyaa:
-
Cufnaanta hoosemarka la barbardhigo galaaska soodhaha-lime, yaraynta miisaanka guud ee qaybta.
-
Waxyaalaha alkali ee la dhimay, yaraynta ion leaching ee hababka falanqaynta xasaasiga ah ama biomedical.
-
Iska caabin la wanaajiyeysi loo weeraro kiimikaad asiidh, alkalis, iyo dareerayaasha organic.
Habka wax-soo-saarka ee Waferka dhalada ee BF33
Waferrada dhalada ah ee BF33 waxaa lagu soo saaraa tillaabooyin dhowr ah oo sax ah oo la xakameeyey. Marka hore, alaabta ceeriin ee nadiifka ah - badiyaa silica, boron oxide, iyo raadadka alkali iyo aluminium oxides - ayaa si sax ah loo miisaamay oo isku qasan. Dufcada waxaa lagu dhalaalin heerkul sare waxaana la sifeeyaa si loo baabi'iyo xumbo iyo wasakh. Isticmaalka habka microfloat-ka, dhalada dhalaalaysa ayaa ku qulqulaya daasad dhalaalaysa si ay u sameeyaan go'yaal siman oo siman. Go'yaashan si tartiib ah ayaa loo tirtiraa si loo yareeyo walbahaarka gudaha, ka dibna la gooyaa taarikada leydi oo sii maran maran maroodiyaal wareegsan. Cidhifyada waferka waa la jeexjeexay ama loo qurxiyey si ay u waarta, oo ay ku xigto sixitaan sax ah iyo midab laba-dhinac ah si loo gaaro sagxadaha aadka u jilicsan. Nadiifinta ultrasonic ka dib qolka nadiifka ah, wafer kastaa wuxuu maraa kormeer adag ee cabbirka, fidsanaanta, tayada indhaha, iyo cilladaha dusha sare. Ugu dambeyntii, maraqyada waxaa lagu baakadeeyay weelal aan wasakh ahayn si loo hubiyo sii haynta tayada ilaa isticmaalka.

FAQ ee BF33 Glass Wafer
Waa maxay galaas BF33?
BF33, oo sidoo kale loo yaqaan BOROFLOAT® 33, waa galaas sabbaynaya borosilicate oo qaali ah oo ay soo saartay SCHOTT iyadoo adeegsanaysa habka microfloat. Waxay bixisaa fidinta kulaylka hooseeya (~ 3.3 × 10⁻ K⁻¹), iska caabin shoog kulayl oo aad u wanaagsan, caddayn sare oo aragga ah, iyo adkaysi kiimikaad oo heer sare ah.
Sidee BF33 uga duwan tahay muraayadda caadiga ah?
Marka la barbar dhigo galaaska soodhaha-lime, BF33:
-
Waxa uu leeyahay is-bahaysi aad u hooseeya ee ballaadhinta kulaylka, isaga oo dhimaya walaaca isbeddelka heerkulka.
-
Miyuu kiimiko ahaan u adkaysan karaa asiidhyada, alkaliska, iyo dareerayaasha.
-
Waxay bixisaa gudbinta UV iyo IR sare.
-
Waxay bixisaa xoog farsamo oo wanaagsan iyo iska caabin xoqan.
Waa maxay sababta BF33 loogu isticmaalo codsiyada semiconductor iyo MEMS?
Balaadhinteeda kulaylka waxay si dhow ula mid tahay silicon, taasoo ka dhigaysa mid ku habboon isku xidhka anodic iyo microfabrication. Joogitaanka kiimikaad waxay sidoo kale u ogolaataa inay u adkaysato xoqidda, nadiifinta, iyo hababka kulaylka sare iyada oo aan hoos u dhicin.
BF33 ma u adkeysan kartaa heerkulka sare?
-
Isticmaalka joogtada ah: ilaa ~450 °C
-
Soo-gaadhista muddada-gaaban (≤ 10 saacadood): ilaa ~ 500 °C
CTE-da hoose waxay sidoo kale siinaysaa iska caabin heer sare ah oo isbeddellada kulaylka degdegga ah.
