Product Features
1, Yepamusoro mazinga ekudzivirira kwezvakatipoteredza: Kusarudza etching kunogona kuwanikwa pasina kushandisa organic mabhesi akadai seTMAH.
2, Mutengo wekugadzira wakaderera: Uchishandisa NaOH/KOH semvura yekuisa, mutengo wakaderera pane iyo acid yekupukuta uye etching maitiro.
3, High etching kunyatsoshanda: Kuenzaniswa neasidhi yekupolisha uye etching maitiro, kushanda kwebhatiri kunowedzerwa nekupfuura 0.15%.
Product Applications
1, Ichi chigadzirwa chinowanzoenderana nePerc uye Topcon bhatiri maitiro;
2, Inokodzera makristasi mamwe e210, 186, 166, uye 158 zvakatemwa.
Mirayiridzo yekushandisa
1, Wedzera huwandu hwakakodzera hwealkali mutangi (1.5-4% zvichienderana neKOH/NAOH vhoriyamu reshiyo)
2, Wedzera huwandu hwakakodzera hwechigadzirwa ichi mutangi (1.0-2% zvichienderana nehuwandu hwehuwandu)
3, Dziyisa mvura yetangi yekupolisha kusvika 60-65°C
4, Isa silicon wafer neshure PSG yakabviswa mutangi rekupukuta, nguva yekuita ndeye 180s-250s.
5, Inokurudzirwa kurasikirwa nehuremu padivi: 0.24-0.30g (210 wafer sosi, mamwe masosi anoshandurwa zvakaenzana) single uye polycrystalline PERC solar masero.
Zvekungwaririra
1, Zvinowedzera zvinoda kuchengetwa zvakanyanya kure nechiedza.
2, Kana mutsara wekugadzira usiri kugadzira, mvura yacho inofanira kuzadzikiswa uye kudonhedzwa maminetsi makumi matatu ega ega.Kana pasina kugadzirwa kwemaawa anopfuura maviri, zvinokurudzirwa kudonhedza uye kuzadzazve mvura.
3, Mutsetse mutsva debugging inoda DOE dhizaini yakavakirwa pane yega yega nzira yekugadzira mutsara kuti uwane maitiro ekufananidza, nekudaro kuwedzera kugona.Iyo inokurudzirwa maitiro inogona kuendeswa kune debugging.
