Cleanroom kos cim ib ntus & txij nkawm: Rau kev sau ntawv, kho cov kab hluav taws xob ib ntus, thiab kho me me yam tsis qhia cov kab mob.
Ultra-High Cleanliness Requirements - Cov qauv tsis sib tham
Cov no yog cov qauv uas paub qhov txawv ntawm semiconductor-qib PTFE daim kab xev los ntawm daim kab xev dav dav. Kev tsis ua raws cai tuaj yeem ua rau tag nrho batch scrapping. Aokai PTFE validates tag nrho cov tsis tau rau peb semiconductor-qib tapes.
