Kwimveliso yebhodi yesekethe eprintiweyo (PCB), ukuchaneka kubaluleke kakhulu. Enye yezinto eziphambili ezichaphazela ukuchaneka yibhedi yegranite esetyenziswa kwiimashini zokubhoboza zePCB. Inkqubo yokumiswa kwezi lathe zegranite idlala indima ebalulekileyo ekuphuculeni ukusebenza kunye nokuchaneka komatshini ngokubanzi.
I-Granite yaziwa ngokuzinza kwayo okugqwesileyo kunye nokuqina kwayo, nto leyo eyenza ukuba ibe yinto efanelekileyo yokusetyenziswa ngokuchanekileyo. Xa iibhedi ze-granite zixhonywe kumatshini wokubhoboza we-PCB, zahlulwe kwiintshukumo kunye nokuphazamiseka kwangaphandle okunokuchaphazela inkqubo yokubhoboza. Le nkqubo yokuxhoboza ivumela i-granite ukuba igcine ukuthamba kwayo kunye nokuchaneka kwayo okulinganayo, nto leyo ebalulekileyo ekuqinisekiseni ukuba imingxunya yokubhoboza ihambelana ngokugqibeleleyo noyilo lwesekethe.
Ukongeza, ukuxhonywa kwebhedi yegranite kunceda ukunciphisa iziphumo zokwanda kobushushu. Njengoko amaqondo obushushu etshintshatshintsha ngexesha lenkqubo yokunyathela, izinto zinokwanda okanye zinciphe, nto leyo enokubangela ukungalungelelani okunokwenzeka. Ngokuxhoma ibhedi yegranite, abavelisi banokunciphisa ezi ziphumo zobushushu, baqinisekise ukuba ibhedi ihlala izinzile kwaye igcine ukuchaneka kokunyathela.
Enye inzuzo ebalulekileyo yebhedi yegranite exhonyiweyo kukukwazi kwayo ukufunxa ukuthuthumela. Ngexesha lokusebenza kwestampu, umatshini uchaphazeleka kumandla ahlukeneyo anokubangela ukungcangcazela. Ibhedi yegranite exhonyiweyo isebenza njengenkqubo yokufunxa, ifunxa ezi mpembelelo kwaye izithintele ekudluliselweni kwiindawo zomatshini. Oku akupheleli nje ekwandiseni ubomi benkonzo yesixhobo, kodwa kukwaphucula nomgangatho wee-PCB ezixhonyiweyo.
Ngamafutshane, ukumiswa kweebhedi zegranite ezichanekileyo kwiimashini zokubhoboza zePCB luphawu oluphambili loyilo lokuphucula ukuchaneka, uzinzo kunye nokuqina. Ngokuhlukanisa igranite ekungcangcazeleni nasekuguquguqukeni kobushushu, abavelisi banokufikelela ekuchanekeni okukhulu kwimveliso yePCB, ekugqibeleni baphucule ukusebenza kwezixhobo ze-elektroniki. Njengoko imfuno yee-PCB ezikumgangatho ophezulu iqhubeka ikhula, ukubaluleka kwale nkqubo yokuvelisa izinto ezintsha akunakugqithiswa.
