Kwihlabathi lokwenziwa kwezinto ze-elektroniki, ingakumbi ekuvelisweni kweebhodi zesekethe eziprintiweyo (ii-PCB), ukuqinisekiswa komgangatho kubaluleke kakhulu. Esinye sezixhobo ezisebenzayo zokuqinisekisa ukuchaneka nokuchaneka kwimveliso ye-PCB kukusetyenziswa kweebhodi zokuhlola zegranite. Ezi ndawo ziqinileyo nezizinzileyo zibonelela ngeenzuzo ezahlukeneyo eziphucula inkqubo yokuqinisekisa umgangatho.
Okokuqala, iipleyiti zokuhlola igranite zibonelela ngokutyibilika okugqwesileyo kunye nokuqina. Iimpawu zendalo zegranite zenza umphezulu ungagcini nje ngokuba tyaba kakhulu, kodwa kwaye ungaguquguquki ngokuhamba kwexesha. Olu zinzo lubalulekile xa kulinganiswa ii-PCB, njengoko nokuba kukho ukungalungelelani okuncinci kunokukhokelela kwiimpazamo ezinkulu kwinkqubo yokwenziwa. Ngokusebenzisa iipleyiti zegranite, abavelisi banokuqinisekisa ukuba imilinganiselo yabo ichanekile, nto leyo ephumela kwiimveliso ezisemgangathweni ophezulu.
Ukongeza, iibhodi zokuhlola igranite zihlala ixesha elide kakhulu kwaye azigugi. Ngokungafaniyo nezinye izinto ezinokonakala okanye zonakale ngokuhamba kwexesha, igranite igcina ukuthembeka kwayo, ibonelela ngesisombululo esihlala ixesha elide sokuqinisekisa umgangatho. Oku kuhlala ixesha elide kuthetha ukuba iindleko zokugcina ziphantsi kwaye azitshintshwa rhoqo, nto leyo eyenza iibhodi zegranite zibe lukhetho olufikelelekayo kubavelisi bePCB.
Enye inzuzo ebalulekileyo yeepleyiti zokuhlola igranite kukuhambelana kwazo nezixhobo ezahlukeneyo zokulinganisa. Nokuba kusetyenziswa ii-calipers, ii-micrometer okanye oomatshini bokulinganisa abadibeneyo (ii-CMM), iipleyiti zegranite zinokuthwala izixhobo ezahlukeneyo, nto leyo ezenza zifaneleke kwizicelo ezahlukeneyo zokuqinisekisa umgangatho. Oku kulungelelaniswa kwenza abavelisi bakwazi ukwenza lula iinkqubo zabo zokuhlola kwaye baphucule ukusebenza kakuhle ngokubanzi.
Ukuqukumbela, iingenelo zeebhodi zokuhlola igranite zokuqinisekisa umgangatho we-PCB zicacile. Ukuthamba kwazo okuhle, ukuqina, kunye nokuhambelana kwazo nezixhobo zokulinganisa kuzenza zibe yimpahla ebalulekileyo kwishishini lemveliso ye-elektroniki. Ngokutyala imali kwiibhodi zokuhlola igranite, abavelisi banokuphucula iinkqubo zabo zokuqinisekisa umgangatho, ekugqibeleni bavelise iimveliso ze-PCB ezisemgangathweni kwaye baphucule ulwaneliseko lwabathengi.
