PFA Lining Mapepala

Zida Zopangira: DuPont PFA resin (USA), yopangidwa mu Class 10,000 clean workshop kuti lining Sheet likhale loyera kwambiri (logwirizana ndi zosowa za semiconductor-grade).
Kachitidwe: RANA imapanga 9,000㎡ PPB/PPT-malo ochitira msonkhano aukhondo ndipo imagwiritsa ntchito njira "yotentha-yosungunuka" kuti iwumbe zinthu zonse, kupeŵa kuipitsidwa ndi tinthu tating'ono panthawi yopanga ndikuwonetsetsa ukhondo wa Mapepala.

Paphata pa Chichewa: Makhalidwe a PFA a "kuyera kwambiri + kukana kuwononga dzimbiri" amapangitsa kuti ikhale chiwiya chokonda kwambiri pazida zodzitchinjiriza-zopanda ukhondo, kupeŵa kuipitsidwa ndi ma ion zitsulo pa TV (monga electronic-grade hydrogen peroxide) ndikuwonetsetsa kuti zokolola zimatsika.
Ubwino: Zotsimikiziridwa ndi SMIC, zomwe zili ndi ayoni yachitsulo zimakhala Zocheperapo kapena zofanana ndi 0.05ppb mutasunga zamagetsi-grade hydrogen peroxide (industry standard 0.1ppb), yokhala ndi kukana kutentha kwa madigiri -200 mpaka 260 degrees . Monga membala wa China Semiconductor Viwanda Association, mankhwalawa adutsa certification okhwima ndi SMIC, BOE ndi mabizinesi ena.

Mmene Mungagwiritsire Ntchito: Zogwiritsidwa ntchito mu semiconductor yapamwamba-zida zoyeretsera (monga, magetsi-matangi osungira giredi hydrofluoric acid) ndi zida za mankhwala (monga matanki osungiramo biological agent) zomwe zimafuna kuyera kwambiri ndi ukhondo wambiri. Zathandiza makasitomala kukonza zokolola za chip (mwachitsanzo, zokolola za 12-inch wafer zawonjezeka ndi 2%) ndikuchepetsa kuwonongeka kwa zinthu zomwe zimawonongeka chifukwa cha zonyansa.
