Amapulatifomu okunemba kwe-granite asetshenziswa kabanzi embonini ye-PCB (Printed Circuit Board) yemishini yokubhoboza ngenxa yezinzuzo zayo eziningi. I-Granite iyitshe lemvelo elaziwa ngokuqina kwayo, ukuzinza, kanye nokunemba kwayo, okwenza ibe yinto efanelekile yamapulatifomu okunemba emishinini yokubhoboza ibhodi lesekethe le-PCB.
Enye yezinzuzo ezibalulekile zokusebenzisa amapulatifomu okunemba kwe-granite ukuzinza kwawo okumangalisayo kanye nokuba yisicaba. I-granite iyinto eqinile futhi eqinile engamelani nokugoba, ukugqwala, kanye nokuguguleka, okuqinisekisa ukuthi ipulatifomu igcina ukuba yisicaba kanye nokuqina kwayo ngokuhamba kwesikhathi. Lokhu kubalulekile emishinini yokubhoboza i-PCB, njengoba noma yikuphi ukuphambuka ekusicabeni kwepulatifomu kungabangela ukungalungi enkambisweni yokubhoboza, okuholela emabhodini wesekethe anephutha.
Ngaphezu kwalokho, i-granite inezakhiwo ezinhle kakhulu zokudambisa ukudlidliza, okubalulekile ekugcineni ukunemba kwenqubo yokubhoboza. Izici zokudambisa ezingokwemvelo ze-granite zisiza ukunciphisa umthelela wokudlidliza komshini, ukuqinisekisa ukubhoboza okunembile nokungaguquguquki kwama-PCB. Lokhu kubaluleke kakhulu lapho usebenza ngemiklamo yebhodi lesifunda ebucayi neyinkimbinkimbi edinga amazinga aphezulu okunemba.
Ngaphezu kwalokho, amapulatifomu okunemba kwe-granite anikeza ukuzinza okuphezulu kokushisa, okusho ukuthi amelana nokushintshashintsha kwezinga lokushisa. Lokhu kunenzuzo ekukhiqizweni kwe-PCB, lapho ukushintsha kwezinga lokushisa kungathinta ukuzinza kobukhulu bezinto zokwakha. Ukuzinza kokushisa kwe-granite kuqinisekisa ukuthi ipulatifomu ayithinteki yizinguquko zokushisa, okuhlinzeka ngendawo ethembekile nengaguquguquki yomshini wokubhoboza.
Enye inzuzo yokusebenzisa amapulatifomu okunemba kwe-granite ukumelana kwawo nomonakalo wamakhemikhali nomswakama. Izindawo zokukhiqiza ze-PCB zivame ukuhilela ukuchayeka kumakhemikhali ahlukahlukene kanye nomswakama, okungalimaza izinto zepulatifomu ngokuhamba kwesikhathi. Ukumelana kwe-granite nalezi zinto kuqinisekisa ukuhlala isikhathi eside kanye nokuthembeka kwepulatifomu yokunemba ezimweni zokukhiqiza ezinzima.
Ekuphetheni, izinzuzo zokusebenzisa amapulatifomu okunemba kwe-granite emishini yokubhoboza ibhodi lesifunda le-PCB zicacile. Ukuqina kwawo, ukuba yisicaba, izakhiwo zokudambisa ukudlidliza, ukuqina kokushisa, kanye nokumelana nomonakalo wamakhemikhali nomswakama kuzenza zibe ukukhetha okuhle kakhulu kokuqinisekisa ukunemba nokuthembeka kwenqubo yokubhoboza ekukhiqizweni kwe-PCB. Ngenxa yalokho, ukusebenzisa amapulatifomu okunemba kwe-granite kungasiza ekuthuthukiseni ikhwalithi yomkhiqizo, ukuncipha kwemfucuza, kanye nokwanda kokukhiqiza embonini ye-PCB.
