Kwibhodi yesekethe eprintiweyo (PCB) yokwenziwa, ukuchaneka kunye nokuqina kubalulekile. Umba ophambili wenkqubo kukunyathela kwePCB, kwaye ukukhethwa kwezinto kumacandelo anesitampu kunokuchaphazela kakhulu umgangatho wemveliso kunye nokusebenza kakuhle. Izinto ezimbini eziqhelekileyo ezisetyenziswe kulo mongo ziyi-granite kunye nentsimbi, nganye ineenzuzo kunye nokungona kwayo.
Amacandelo e-Granite ayaziwa ngokuzinza kwawo okungaqhelekanga kunye nokuqina. Ubuninzi bamatye endalo bubonelela ngesiseko esiluqilima esinciphisa ukungcangcazela ngexesha lenkqubo yesitampu, ngaloo ndlela sinyusa ukuchaneka kunye nokunciphisa ukuguga kwezixhobo zesitampu. Olu uzinzo lunenzuzo ngokukhethekileyo kwizicelo zesantya esiphezulu, apho nokuba ukunyakaza okuncinci kunokubangela ukungahambi kakuhle kunye neziphene. Ukongezelela, i-granite iyamelana nokwandiswa kwe-thermal, iqinisekisa ukusebenza okuhambelanayo kumaqondo okushisa ahlukeneyo, okubaluleke kakhulu kwiindawo apho ukuveliswa kobushushu kuyinkxalabo.
Amacandelo ensimbi, kwelinye icala, akhethwa ngenxa yamandla kunye nokuqina. Amalungu ensimbi ayinakwenzeka ukuba aqhekeze ngaphezu kwegranite, ezenza ukuba zibe lukhetho oluthembekileyo kwimveliso ephezulu. Ukongezelela, amacandelo ensimbi angenziwa lula kwaye alungiselelwe ukuhlangabezana neemfuno ezithile, ukubonelela ukuguquguquka koyilo olungenakulinganiswa negranite. Nangona kunjalo, amacandelo entsimbi athanda ukugqwala kunye ne-corrosion, enokuthi ibe yingozi enkulu kwiindawo ezifumileyo okanye ezinobume bekhemikhali.
Xa kuthelekiswa ukusebenza kwegranite kunye nentsimbi kwizicelo zesitampu zePCB, isigqibo sokugqibela sixhomekeke kwiimfuno ezithile zenkqubo yokuvelisa. Kwimisebenzi apho ukuchaneka kunye nokuzinza kubaluleke kakhulu, igranite inokuba lolona khetho lungcono. Ngokwahlukileyo, kwezo zinto zifuna ukuqina kunye nokuguquguquka, intsimbi inokuba luncedo ngakumbi. Ukuqonda iimpawu ezizodwa zemathiriyeli nganye kubalulekile kubavelisi abajolise ekuphuculeni iinkqubo zabo zemveliso yePCB.
