Khasete ea Wafer

Tlhaloso e Khutšoanyane:

Khasete ea Wafer- E entsoe ka mokhoa o nepahetseng bakeng sa ts'ebetso e bolokehileng le polokelo ea li-wafers tsa semiconductor, ho netefatsa tšireletso e nepahetseng le bohloeki nakong eohle ea tlhahiso.

Lisosa tsa SemiceraKhasete ea Waferke karolo ea bohlokoa ts'ebetsong ea tlhahiso ea semiconductor, e etselitsoeng ho ts'oara le ho tsamaisa liphaephe tse bobebe tsa semiconductor. TheKhasete ea Wafere fana ka tshireletso e ikgethang, ho netefatsa hore sephaphatha ka seng se bolokwa ntle le ditshila le tshenyo ya mmele nakong ya ho tshwara, ho bolokwa le ho palangwa.

E entsoe ka thepa ea boleng bo holimo, e hananang le lik'hemik'hale, SemiceraKhasete ea Wafere netefatsa maemo a phahameng ka ho fetisisa a bohloeki le ho tšoarella, a bohlokoa bakeng sa ho boloka botšepehi ba li-wafers mohatong o mong le o mong oa tlhahiso. Boenjiniere bo nepahetseng ba lik'hasete tsena bo lumella ho kopanngoa ka mokhoa o se nang moeli le mekhoa ea ho tšoara ka mokhoa o ikemetseng, ho fokotsa kotsi ea tšilafalo le tšenyo ea mechine.
