Pob zeb diamond sib tsoo log siv hauv photovoltaic
Dec 06, 2022
Silicon belongs rau cov khoom tawv thiab nkig, mohs hardness yog 6.5, tuaj yeem ua polycrystalline silicon, monocrystalline silicon raws li kev siv.
Monocrystalline silicon (MONocrystalline silicon) yog ib qho tseem ceeb uas tsis yog hlau. Nrog rau lub hauv paus ua tiav lattice qauv, monocrystalline silicon (MONocrystalline silicon) yog cov khoom siv semiconductor zoo nrog cov purity ntawm 99.9999 feem pua. Nws yog tsuas yog siv rau kev tsim khoom siv hluav taws xob semiconductor thiab lub hnub ci hlwb.
Monocrystalline silicon feem ntau yog tsim los ntawm thawj zaug ua polycrystalline silicon los yog amorphous silicon thiab tom qab ntawd loj hlob qws zoo li monocrystalline silicon los ntawm cov yaj los ntawm kev rub ncaj qha los yog ncua kev kawm fusion txoj kev.
Polycrystalline silicon yog ib daim ntawv ntawm elemental silicon. Thaum molten elemental silicon solidifies nyob rau hauv cov xwm txheej ntawm supercooling, silicon atoms tau teem rau hauv ntau cov siv lead ua nuclei nyob rau hauv daim ntawv ntawm pob zeb diamond lattice. Piv txwv li, cov khoom siv lead ua no loj hlob mus rau hauv cov nplej nrog cov kev taw qhia sib txawv ntawm cov khoom siv lead ua, thiab cov nplej no ua ke kom crystallize rau hauv polycrystalline silicon.
Polysilicon yog cov khoom siv ncaj qha ntawm monocrystalline silicon, thiab nws yog cov ntaub ntawv hluav taws xob cov ntaub ntawv ntawm cov khoom siv dag zog, kev tswj tsis siv neeg, cov ntaub ntawv ua, kev hloov pauv photoelectric thiab lwm yam khoom siv semiconductor.
Nws yog hu ua "lub hauv paus pob zeb ntawm lub microelectronics tsev".
Machining txheej txheem
Kev ua cov txheej txheem ntawm monocrystalline silicon feem ntau suav nrog: truncation, spherification, txiav, sib tsoo, chamfering, sib tsoo, tshuaj corrosion, polishing thiab lwm yam.
Hauv qhov sib piv, polysilicon tsis muaj truncation thiab spherification cov kauj ruam thiab tsuas yog yuav tsum tau txiav square thiab hlais tom qab kev npaj tiav lawm.
Nyob rau hauv tag nrho cov txheej txheem ntawm kev npaj ntawm monocrystalline silicon thiab polycrystalline silicon los ntawm pas nrig mus rau nti, pob zeb diamond cov cuab yeej ntawm USES sib txawv yuav tsum tau koom nyob rau hauv kev ua, thiab kev ua precision yog kuj siab.
Monocrystalline silicon pas nrig sib tsoo log
Ib leeg siv lead ua pob zeb sib tsoo log, dav dav yog 1A1 300*25 (35,40) * 127 * 7, nyob rau hauv daim ntawv ntawm ib nti thiab ua ke.
Nws yog ib qho kev sib tsoo log nrog ntau cov granularity (D 120/140, 200/230, W40), uas tuaj yeem ua tiav kev ua haujlwm siab thiab ua haujlwm zoo ib txhij.
Txhawb cov cuab yeej siv tshuab suav nrog Wuxi on-machine WSK003, Wuxi qhib qhov WX-7321/2 thiab lwm yam
Nto chamfering log
Chamfering ntawm mono-crystal silicon sib tsoo nto thiab polycrystalline silicon sib tsoo nto kuj yuav tsum muaj ntau ntawm pob zeb diamond sib tsoo log. Cov txheej txheem ua tau muab faib ua ntxhib sib tsoo thiab sib tsoo zoo, nrog cov pob zeb diamond particle loj ntawm 120/140, W40, W28, W20, thiab lwm yam. Qhov loj me yog 6A2 220 * 65 * 130 * 5 * 5, 6A 2 200*60*80*5*5, 11A{19}}*28(40)*31.75(20)*5*5, thiab lwm yam.
Cov cuab yeej siv tshuab hauv tsev ntau dua, ib feem ntawm qhov chaw chamfering tag nrho-hauv-ib lub tshuab tuaj yeem ua ib qho polycrystalline arc lossis lub kaum sab xis, polishing nto.
