PCB kuningi kwemishini ye-elektroniki ngenkathi kuhlanganiswa ukhiye obalulekile, izinkampani zisekuthengweni kwezimpahla ukuze zibe nekhwalithi zibe nomthethonqubo ophakeme, kufanele ziqinisekise ikhwalithi ngemuva kwe-PCB engakhuthaza izinkomba zokusebenza kwemishini ye-elekthronikhi, futhi ingenza impahla isebenze ngokuphelele ukusebenza okuyinhloko kungavimbela ukubambezeleka kwezimo ezahlukahlukene.Ngezansi xoxa ukuhlukanisa ikhwalithi yebhodi le-PCB amazinga amaningana wokuqukethwe:

Okokuqala, hlukanisa nokubukeka

I-PCB kunqubo yesidingo sokukhiqiza ngokusebenzisa izinhlobonhlobo zokucubungula okunzima ukuhlangabezana, kusuka emgodini womshini we-CNC ukuwasha izandla, ukomisa, ukugoqa umgqomo ukuze unamathele ezansi komugqa ophezulu wesikrini sokuphrinta kwesikrini futhi yonke inqubo yenqubo yokusebenza ngayinye isengozini wonke umkhiqizo wokukhiqiza we-PCB nekhwalithi yokucubungula, ukuze uhlukanise nekhwalithi yokubukeka, ukuthuthukisa igxathu negxathu ukukhomba ikhava engoyinki yokuphrinta ebonakalayo ngesikhathi esifanele, Indawo yethusi ngaphandle kwesimo se-oxidation yomoya ngaphezu kwakho konke isimo senguquko engabonakali ebusweni singahambisana nezinhlinzeko zekhwalithi.

Okwesibili, kusuka ngosayizi nobukhulu besinqumo

Incazelo yohlelo lokusebenza ayifani nobukhulu be-PCB ubuchwepheshe nobukhulu bayo, ikhasimende alikwazanga ukutshela indinganiso efanayo yekhwalithi yomkhiqizo ukwenza ukuhlolwa ngokusho kwemininingwane, bheka ubukhulu bayo bensimbi yemodeli ye-PCB buhambisana imininingwane, ingenza amazinga wobuchwepheshe ngosayizi wayo futhi ubukhulu bayo ekusetshenzisweni kwekhwalithi yezimpahla kuyaqinisekiswa.

Okwesithathu, kusukela ezingxenyeni zokuqina kokushisela

I-PCB efakwe ezingxenyeni eziningi zezinto ze-elekthronikhi, zonke izingxenye ze-elekthronikhi zivame ukuba nendima ekhethekile ekudlaleni okugcwele, ukuqinisekisa ukuthi ikhwalithi ye-PCB yonke yenza okuhle, ukusetshenziswa kokushaqeka kungahle kuveze zonke izinto zikagesi zokushisela i-welding eqinile akulula ukuwa phansi, ezinye izinto zihlele yonke i-oda zicace shazi, Lokhu konke kungasetshenziswa ukuhlukanisa ikhwalithi yokuqukethwe okuhlobene nebhodi le-PCB.

Ngoba ibhodi le-PCB liyinsimbi yomhlangano womshini wokhiye we-elekthronikhi, ngakho-ke ekusetshenzisweni kwezidingo eziqinile zekhwalithi. Ngakho-ke okuphakanyisiwe ukuthi ikhasimende lidinga ukukhetha ikhwalithi yokukhetha nokuthenga ukuqinisekisa ukuthi abakhiqizi abangochwepheshe abenza ukuthengwa kobuchwepheshe be-PCB, abakhiqizi abanabo ubuchwepheshe bokuzenzakalela kuphela, imishini yokukhiqiza esezingeni eliphakeme kanye nolayini bokukhiqiza, futhi kunqubo yokukhiqiza efanele ngokuqinile ukulawula ikhwalithi, kungaqinisekisa ukukhiqiza imikhiqizo yekhwalithi ephezulu ye-PCB yekhwalithi ephezulu yabo bonke abathengi.
