Amaphutha e-Granite asetshenziswa emikhiqizweni yemishini yokucubungula i-wafer

I-Granite iyidwala elivela ngokwemvelo elisetshenziswe isikhathi eside emishinini yokucubungula i-wafer. Yaziwa ngezakhiwo zayo ezinhle kakhulu zokuba nokukhula okuphansi kokushisa, ukuqina okuphezulu kanye nokuqina okuhle. Kodwa-ke, njengazo zonke izinto, i-granite inesethi yayo yeziphambeko ezingathinta ikhwalithi yemishini yokucubungula i-wafer.

Esinye seziphambeko ezinkulu ze-granite ukuthambekela kwayo kokuqhekeka noma ukuphuka. Lokhu kungenxa yokuba khona kwemifantu emincane engenzeka ngesikhathi sokwakheka kwedwala. Uma le mifantu emincane ingatholakali futhi ingaphathwa kahle, inganda futhi iholele ekungasebenzi kahle kwemishini. Ukuze kuvinjelwe lokhu kungenzeki, abakhiqizi bemishini yokucubungula kudingeka basebenzise i-granite esezingeni eliphezulu eselashwe futhi yahlolwa ukuqinisekisa ukuthi ayinayo imifantu emincane.

Esinye isici se-granite ukuthi isengozini yokugqwala. Uma imishini ye-granite ihlangana nezindawo ezigqwala, ingaqala ukuwohloka ngokuhamba kwesikhathi. Lokhu kungaholela ekutheni imishini yonakale noma ingasebenzi kahle. Ukuze kuvinjelwe lokhu, abakhiqizi kumele baqinisekise ukuthi i-granite esetshenziswa emishinini yabo iphathwa kahle futhi imbozwe ukuze kuvinjelwe noma yikuphi ukugqwala.

I-granite nayo ithambekele ekugobekeni ngokuhamba kwesikhathi ngenxa yezakhiwo zayo zokushisa ezingokwemvelo. Lokhu kungenxa yokuthi i-granite ine-coefficient ephansi kakhulu yokwanda kokushisa, okusho ukuthi ayikhuli noma ayinciphisi kakhulu uma ishintsha izinga lokushisa. Kodwa-ke, ngisho nokwanda okuncane noma ukugobeka kungabangela ukugobeka emishinini ngokuhamba kwesikhathi. Kubalulekile ukuthi umenzi wemishini acabangele izakhiwo zokushisa ze-granite lapho eklama imishini yakhe ukuze avimbele lokhu kuphazamiseka.

Okokugcina, isimo se-granite sokuba nezimbobo singaholela ezinkingeni zokungcola. Uma i-granite ingavalwanga kahle, ingamunca ukungcola okungathinta ikhwalithi ye-wafer. Lokhu kungaholela ekulahlekelweni isikhathi esiningi kanye nokulahleka komkhiqizo. Ukuze kuvinjelwe lokhu, abakhiqizi kudingeka bayivale kahle i-granite ukuze bavimbele noma yikuphi ukungcola ukuthi kungene.

Ekuphetheni, i-granite iyinto enhle kakhulu yokusetshenziswa emishinini yokucubungula i-wafer. Kodwa-ke, kubalulekile ukuqaphela amaphutha ayo futhi uthathe izinyathelo zokuphepha ezidingekayo ukuze uvimbele ukuthi angenzeki. Ngokunakekelwa nokugcinwa okufanele, imishini ye-granite ingaqhubeka isebenza iminyaka eminingi, inikeze ama-wafer asezingeni eliphezulu embonini ye-semiconductor.
