\"BOROFLOATBOROFLOAT 33 BF33 glasplatta f\u00f6r MEMS-plattbindning och optisk f\u00f6rpackning<\/h4>\n

BF33 (BOROFLOAT 33) \u00e4r en skiva av borosilikatglas med l\u00e5g utvidgning som anv\u00e4nds i stor utstr\u00e4ckning vid tillverkning av halvledare, MEMS-komponenter, optiska kapslingar och mikrofluida enheter. Tack vare sin utm\u00e4rkta termiska stabilitet, h\u00f6ga optiska transparens och \u00f6verl\u00e4gsna ytkvalitet har BF33 blivit ett av de vanligaste glassubstraten f\u00f6r kiselbindningsapplikationer.<\/p>\n

Dess v\u00e4rmeutvidgningskoefficient \u00f6verensst\u00e4mmer i h\u00f6g grad med kisel, vilket m\u00f6jligg\u00f6r tillf\u00f6rlitlig anodisk bindning och minimerar termisk sp\u00e4nning vid bearbetning vid h\u00f6ga temperaturer. BF33-skivor finns i olika diametrar, tjocklekar och poleringsgrader f\u00f6r att uppfylla olika processkrav p\u00e5 skivniv\u00e5.<\/p>\n

        Typiska till\u00e4mpningar<\/h2>\n

        MEMS-tillverkning<\/h3>\n

        BF33-glasplattor anv\u00e4nds i stor utstr\u00e4ckning som t\u00e4ckplattor och bindningsplattor i MEMS-sensorer, trycksensorer, accelerometrar, gyroskop och mikroaktuatorer.<\/p>\n

        Anodisk bindning av kisel<\/h3>\n

        Den termiska expansionsanpassningen mellan BF33 och kisel g\u00f6r det till ett idealiskt substrat f\u00f6r anodiska bindningsprocesser som anv\u00e4nds vid f\u00f6rpackning p\u00e5 wafer-niv\u00e5 och hermetisk f\u00f6rsegling.<\/p>\n

        Mikrofluidiska enheter<\/h3>\n

        BF33 har utm\u00e4rkt transparens och kemisk best\u00e4ndighet, vilket g\u00f6r det l\u00e4mpligt f\u00f6r lab-on-chip-enheter, mikroreaktorer och biomedicinska diagnostiksystem.<\/p>\n

        Optisk f\u00f6rpackning<\/h3>\n

        Materialet anv\u00e4nds ofta till optiska f\u00f6nster, laserh\u00f6ljen, fotoniska komponenter, optiska filter och bildbehandlingsmoduler.<\/p>\n

        B\u00e4rare f\u00f6r halvledarprocesser<\/h3>\n

        BF33-skivor kan \u00e4ven anv\u00e4ndas som b\u00e4rskivor vid tillf\u00e4llig sammanfogning, skivf\u00f6rtunning och avancerade halvledarf\u00f6rpackningsprocesser.<\/p>\n

        \n<\/div>\n

        Varf\u00f6r v\u00e4lja BF33-glasplatta?<\/h2>\n

        J\u00e4mf\u00f6rt med konventionellt sodaglas erbjuder BF33 avsev\u00e4rt b\u00e4ttre termisk stabilitet, l\u00e4gre termisk expansion, h\u00f6gre optisk kvalitet och \u00f6verl\u00e4gsen kemisk best\u00e4ndighet. Dessa f\u00f6rdelar g\u00f6r det till ett f\u00f6redraget substratmaterial f\u00f6r avancerad MEMS-tillverkning, optisk integration och till\u00e4mpningar inom wafer-level packaging.<\/p>\n

        Tack vare sin utm\u00e4rkta planhet, l\u00e5ga defektdensitet och h\u00f6ga bindningss\u00e4kerhet \u00e4r BF33 fortfarande ett av de mest anv\u00e4nda materialen f\u00f6r glaswafers inom halvledar- och fotonikindustrin.<\/p>\n

        VANLIGA FR\u00c5GOR<\/h2>\n

        Vad \u00e4r skillnaden mellan BF33 och vanligt glas?<\/h3>\n

        BF33 inneh\u00e5ller en h\u00f6g andel kiseldioxid och boroxid, vilket ger l\u00e4gre v\u00e4rmeutvidgning, b\u00e4ttre kemisk best\u00e4ndighet och h\u00f6gre optisk prestanda \u00e4n konventionellt natriumkalciumglas.<\/p>\n

        \u00c4r BF33 l\u00e4mpligt f\u00f6r anodisk bindning med kisel?<\/h3>\n

        Ja. BF33 \u00e4r ett av de vanligaste glasmaterialen f\u00f6r anodisk bindning med kisel, eftersom dess v\u00e4rmeutvidgningskoefficient ligger mycket n\u00e4ra kiselets.<\/p>\n

        Kan BF33-skivor levereras med dubbelsidig polering?<\/h3>\n

        Ja. Det finns b\u00e5de SSP- och DSP-skivor. DSP-skivor kan uppn\u00e5 en ytj\u00e4mnhet p\u00e5 under 1 nm och \u00e4r l\u00e4mpliga f\u00f6r skivbindning med h\u00f6g precision.<\/p>\n

        Kan ni tillhandah\u00e5lla skivor i anpassade storlekar och tjocklekar?<\/h3>\n

        Ja. Vi kan tillverka produkter med anpassade diametrar, tjocklekar, kantprofiler och poleringsspecifikationer enligt kundens \u00f6nskem\u00e5l.<\/p>","protected":false},"excerpt":{"rendered":"
