Amaqonga okuchaneka kwegranite asetyenziswa kakhulu kwishishini le-PCB (Printed Circuit Board) kwiimashini zokubhoboza ngenxa yeenzuzo ezininzi. Igranite lilitye lendalo elaziwa ngokuqina, ukuzinza, kunye nokuchaneka kwalo, okwenza ukuba libe yinto efanelekileyo kwiiplatifomu zokuchaneka kwiimashini zokubhoboza iibhodi zesekethe ze-PCB.
Enye yeenzuzo eziphambili zokusebenzisa amaqonga okuchaneka kwegranite kukuzinza kwawo okugqwesileyo kunye nokuba tyaba. Igranite yinto eqinileyo neqinileyo ekwaziyo ukumelana nokugoba, ukubola, kunye nokuguguleka, okuqinisekisa ukuba iqonga ligcina lithambekile kwaye lizinzile ngokuhamba kwexesha. Oku kubalulekile kwiimashini zokubhoboza zePCB, njengoko naluphi na uphambuko kwindlela ethambekileyo yeqonga lunokubangela ukungachaneki kwinkqubo yokubhoboza, okukhokelela kwiibhodi zesekethe ezineziphene.
Ukongeza, i-granite ineempawu ezintle kakhulu zokudambisa ukungcangcazela, nto leyo ebalulekileyo ekugcineni ukuchaneka kwenkqubo yokubhoboza. Iimpawu ze-granite zokudambisa ezisisiseko zinceda ukunciphisa impembelelo yokungcangcazela koomatshini, ukuqinisekisa ukubhoboza okuchanekileyo nokungaguquguqukiyo kwee-PCB. Oku kubaluleke kakhulu xa usebenza ngoyilo lweebhodi zesekethe ezibuthathaka nezintsonkothileyo ezifuna amanqanaba aphezulu okuchaneka.
Ngaphezu koko, amaqonga okuchaneka kwegranite anika uzinzo oluphezulu lobushushu, oko kuthetha ukuba ayamelana nokuguquguquka kobushushu. Oku kuluncedo kwimveliso ye-PCB, apho ukutshintsha kobushushu kunokuchaphazela uzinzo lobukhulu bezinto. Uzinzo lobushushu lwegranite luqinisekisa ukuba iqonga alichaphazeleki lutshintsho lobushushu, nto leyo enika umphezulu othembekileyo nongaguqukiyo kumatshini wokubhoboza.
Enye inzuzo yokusebenzisa amaqonga okuchaneka kwegranite kukuchaneka kwawo kumonakalo weekhemikhali kunye nokufuma. Iindawo zokwenza iiPCB zihlala ziquka ukuvezwa kwiikhemikhali ezahlukeneyo kunye nokufuma, okunokonakalisa izinto zeqonga ngokuhamba kwexesha. Ukuchaneka kwegranite kwezi zinto kuqinisekisa ukuba iqonga lokuchaneka lihlala ixesha elide kwaye lithembekile kwiimeko ezinzima zokwenza.
Ukuqukumbela, iingenelo zokusebenzisa amaqonga okuchaneka kwegranite kwiimashini zokubhoboza iibhodi zesekethe ze-PCB zicacile. Uzinzo lwazo, ukuthamba kwazo, iimpawu zokudambisa ukungcangcazela, uzinzo lobushushu, kunye nokumelana nomonakalo weekhemikhali kunye nokufuma kuzenza zibe lukhetho oluhle kakhulu lokuqinisekisa ukuchaneka nokuthembeka kwenkqubo yokubhoboza kwimveliso ye-PCB. Ngenxa yoko, ukusebenzisa amaqonga okuchaneka kwegranite kunokunceda ekuphuculeni umgangatho wemveliso, ukunciphisa inkunkuma, kunye nokwanda kwemveliso kwishishini le-PCB.
