Txheej txheem cej luam ntawm BF33 Iav Wafer
Lub iav wafer BF33, uas tau lees paub thoob ntiaj teb raws li lub npe lag luam BOROFLOAT 33, yog lub iav borosilicate zoo tshaj plaws uas SCHOTT tsim los ntawm kev siv txoj kev tsim khoom microfloat tshwj xeeb. Cov txheej txheem tsim khoom no xa cov ntawv iav nrog cov tuab sib xws, qhov chaw tiaj tus zoo heev, qhov me me ntawm qhov ntxhib, thiab qhov pom tseeb zoo heev.
Ib qho tseem ceeb ntawm BF33 yog nws cov coefficient qis ntawm thermal expansion (CTE) ntawm kwv yees li 3.3 × 10-6 K-1, ua rau nws zoo tagnrho rau cov silicon substrates. Cov cuab yeej no ua rau kev koom ua ke tsis muaj kev ntxhov siab hauv microelectronics, MEMS, thiab optoelectronic devices.
Cov Khoom Siv Muaj pes tsawg leeg ntawm BF33 Iav Wafer
BF33 yog ib yam khoom siv iav borosilicate uas muaj ntau tshaj li lwm yam khoom siv iav.80% silica (SiO2), nrog rau boron oxide (B2O3), alkali oxides, thiab cov txhuas oxide me me. Cov mis no muab:
-
Qhov ceev qis duapiv rau cov iav soda-lime, txo qhov hnyav tag nrho.
-
Txo cov ntsiab lus alkali, txo cov ion leaching hauv cov txheej txheem analytical lossis biomedical rhiab heev.
-
Kev tiv thaiv zoo duativ thaiv kev puas tsuaj los ntawm cov kua qaub, alkalis, thiab cov organic solvents.
Cov Txheej Txheem Ntau Lawm ntawm BF33 Iav Wafer
Cov iav wafers BF33 yog tsim los ntawm ntau cov kauj ruam tswj hwm. Ua ntej, cov khoom siv raw khoom uas muaj kev ntshiab siab - feem ntau yog silica, boron oxide, thiab cov alkali thiab txhuas oxides - raug ntsuas thiab sib xyaw kom raug. Cov khoom no yaj ntawm qhov kub siab thiab ua kom huv si kom tshem tawm cov npuas thiab cov khoom tsis huv. Siv cov txheej txheem microfloat, cov iav molten ntws hla cov tin molten los ua cov ntawv tiaj tus, sib xws. Cov ntawv no maj mam annealed kom txo qhov kev ntxhov siab sab hauv, tom qab ntawd txiav rau hauv cov phaj rectangular thiab ntxiv blanked rau hauv cov wafers puag ncig. Cov npoo ntawm wafer yog beveled lossis chamfered rau kev ruaj khov, ua raws li kev lapping precision thiab ob sab polishing kom ua tiav cov nplaim du. Tom qab ntxuav ultrasonic hauv chav huv, txhua wafer raug tshuaj xyuas nruj rau qhov ntev, flatness, optical zoo, thiab qhov tsis zoo ntawm qhov chaw. Thaum kawg, wafers raug ntim rau hauv cov thawv tsis muaj kuab paug kom ntseeg tau tias zoo khaws cia kom txog thaum siv.

Cov Lus Nug Txog BF33 Iav Wafer
BF33 iav yog dab tsi?
BF33, tseem hu ua BOROFLOAT® 33, yog ib lub iav borosilicate zoo tshaj plaws uas SCHOTT tsim los ntawm kev siv cov txheej txheem microfloat. Nws muaj kev nthuav dav thermal qis (~ 3.3 × 10⁻⁶ K⁻¹), tiv taus kev poob siab thermal zoo heev, pom tseeb optical siab, thiab ua tau zoo heev rau tshuaj lom neeg.
BF33 txawv li cas ntawm cov iav ib txwm?
Piv rau cov iav soda-lime, BF33:
-
Muaj cov coefficient qis dua ntawm kev nthuav dav thermal, txo kev ntxhov siab los ntawm kev hloov pauv kub.
-
Nws muaj zog tiv taus cov kua qaub, alkalis, thiab cov kuab tshuaj ntau dua li cov tshuaj lom neeg.
-
Muab kev sib kis UV thiab IR siab dua.
-
Muab lub zog zoo dua thiab khawb tsis kam.
Vim li cas BF33 thiaj siv rau hauv cov ntawv thov semiconductor thiab MEMS?
Nws qhov kev nthuav dav thermal sib xws nrog silicon, ua rau nws zoo tagnrho rau kev sib txuas anodic thiab microfabrication. Nws cov tshuaj lom neeg ruaj khov kuj tso cai rau nws kom nyiaj tau etching, ntxuav, thiab cov txheej txheem kub siab yam tsis muaj kev puas tsuaj.
BF33 puas tuaj yeem tiv taus qhov kub siab?
-
Siv tas mus li: txog li ~ 450 ° C
-
Kev raug rau lub sijhawm luv luv (≤ 10 teev): txog li ~ 500 ° C
Nws cov CTE qis kuj ua rau nws tiv taus kev hloov pauv sai sai ntawm thermal.
