Isayensi Engemuva Kokunemba Kwe-Granite Ekukhiqizweni Kwe-PCB.

 

Embonini ye-elekthronikhi, ukunemba kubalulekile, ikakhulukazi ekukhiqizweni kwamabhodi wesekethe aphrintiwe (ama-PCB). I-Granite iyitshe lesisekelo salokhu kunemba futhi ingenye yezinto ezithakazelisa kakhulu. Isayensi ngemuva kwendima ye-granite ekukhiqizweni kwe-PCB iyinhlanganisela ethakazelisayo ye-geology, ubunjiniyela, kanye nobuchwepheshe.

I-Granite iyitshe lemvelo elakhiwe ngokuyinhloko nge-quartz, i-feldspar, kanye ne-mica enikeza ukuzinza nokuqina okumangalisayo. Lezi zakhiwo zenza i-granite ibe yinto efanelekile yokukhiqiza izindawo zokukhiqiza ze-PCB. Ukuthamba nokuqina kwama-granite slabs kunikeza ipulatifomu ezinzile yezinqubo eziyinkimbinkimbi ezihilelekile ekukhiqizweni kwe-PCB, njenge-photolithography kanye nokuqopha. Noma yikuphi ukuphambuka ekuthambekeni kobuso kungabangela amaphutha amakhulu ekulinganisweni kwezingxenye, okuphazamisa ukusebenza komkhiqizo wokugcina.

Ngaphezu kwalokho, ukuzinza kokushisa kwe-granite kungenye into ebalulekile. Ngesikhathi senqubo yokukhiqiza i-PCB, ukushisa kuhilelekile ezigabeni ezahlukene. I-granite ingamelana namazinga okushisa aphezulu ngaphandle kokugoba noma ukuguquka, okuqinisekisa ukuthi ukunemba kokwakheka kwe-PCB kugcinwa kulo lonke umjikelezo wokukhiqiza. Lokhu kuqina kokushisa kubalulekile ezinqubweni ezifana nokushisela, lapho ukushintshashintsha kwezinga lokushisa kungabangela ukungalungi kanye nokukhubazeka.

Ngaphezu kwalokho, imvelo ye-granite ayinazo izimbobo ivimbela ukungcola, okuyinto ebalulekile endaweni ehlanzekile lapho kukhiqizwa khona ama-PCB. Uthuli nezinhlayiya kungaphazamisa kalula izinqubo ezibucayi ezihilelekile ekukhiqizweni kwama-PCB, futhi ubuso be-granite buyasiza ekunciphiseni le ngozi.

Ngamafuphi, isisekelo sesayensi sokunemba kwe-granite ekukhiqizweni kwe-PCB sisezicini zayo eziyingqayizivele zomzimba. Ukuqina kwe-granite, ukumelana nokushisa, kanye nokuhlanzeka kwayo kuyenza ibe yinto ebalulekile embonini ye-elekthronikhi, okuqinisekisa ukuthi ama-PCB akhiqizwayo asezingeni eliphezulu futhi anokwethenjelwa. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, i-granite ngokungangabazeki izoqhubeka nokudlala indima ebalulekile ekuphishekeleni ukunemba ekukhiqizweni kwe-elekthronikhi.
