Kwimveliso yebhodi yesekethe eprintiweyo (PCB), ukuchaneka nokuqina kubalulekile. Inkalo ephambili yale nkqubo kukunyathelisa i-PCB, kwaye ukukhethwa kwezinto ezisetyenzisiweyo kwiindawo ezinyathelweyo kunokuchaphazela kakhulu umgangatho kunye nokusebenza kakuhle kwemveliso. Izixhobo ezimbini eziqhelekileyo ezisetyenziswayo kule meko yigranite kunye nentsimbi, nganye ineenzuzo kunye neengxaki zayo.
Izinto zegranite zaziwa ngokuzinza kwazo okumangalisayo kunye nokuqina kwazo. Uxinano lwelitye lendalo lubonelela ngesiseko esiqinileyo esinciphisa ukungcangcazela ngexesha lenkqubo yokunyathela, ngaloo ndlela kwandisa ukuchaneka kunye nokunciphisa ukuguguleka kwezixhobo zokunyathela. Olu zinzo luluncedo ngakumbi kwizicelo zesantya esiphezulu, apho nokuba yintshukumo encinci inokubangela ukungalungelelani kunye neziphene. Ukongeza, igranite ayimelani nokwanda kobushushu, iqinisekisa ukusebenza rhoqo kumaqondo obushushu ahlukeneyo, nto leyo ibalulekileyo kwiindawo apho ukuveliswa kobushushu kuyingxaki.
Kwelinye icala, izinto zentsimbi zikhethwa ngenxa yokuba zinamandla kwaye zihlala ixesha elide. Izinto zentsimbi azikwazi ukuqhekezwa njengegranite, nto leyo eyenza ukuba zibe lukhetho oluthembekileyo kwimveliso enomthamo omkhulu. Ukongeza, izinto zentsimbi zinokucutshungulwa ngokulula kwaye zenziwe ngokwezifiso ukuhlangabezana neemfuno ezithile, nto leyo enika ukuguquguquka koyilo olungenakufanelwa yigranite. Nangona kunjalo, izinto zentsimbi zisengozini yokugqwala nokugqwala, nto leyo enokuba yingxaki enkulu kwiindawo ezifumileyo okanye ezinobungozi beekhemikhali.
Xa kuthelekiswa ukusebenza kwegranite kunye nentsimbi kwizicelo ze-PCB stamping, isigqibo sokugqibela sixhomekeke kwiimfuno ezithile zenkqubo yokuvelisa. Kwimisebenzi apho ukuchaneka kunye nozinzo kubalulekile, igranite isenokuba lolona khetho lufanelekileyo. Ngokwahlukileyo koko, kwimisebenzi efuna ukuqina kunye nokuguquguquka, intsimbi inokuba luncedo ngakumbi. Ukuqonda iipropati ezizodwa zesixhobo ngasinye kubalulekile kubavelisi abajonge ukuphucula iinkqubo zabo zemveliso ye-PCB.
