Ukunyanzeliswa kwe-PCB kubhekisele kwiiparamitha zokuxhathisa kunye nokusebenza, edlala indima yo-one-absupstan ekutshintsheni okwangoku. Kwimveliso yeBhodi yeBhodi yeBhodi, unyango lokuKhulula lubalulekile. Ngaba uyazi ukuba kutheni iibhodi zesekethe zePCB kufuneka zenziwe?

I-1, iBhodi yeSekethi yePCB esezantsi ukuze ithathele ingqalelo ukufakwa kwezinto ze-elektroniki, ukwenziwa kombane kunye nokuhambisa umqondiso emva kokufakelwa, kuya kufuna ukuba kunciphise ukubupolwa, ukumelana, ukuxhathisa kungaphantsi kwesentimitha enye.

I-2, iBhodi yeSekethe yePCB kwinkqubo yemveliso yokufumana i-tinking yobhedu, i-tin ye-tin (okanye i-ensoeds e-conness, kwaye i-spin ye-Inch Rine), i-Spring esetyenziswayo i-CIN), i-SPRAY YENDLELA YOKUFUNDA I-PCB iphantsi ukuhlangabezana neemfuno ezisemgangathweni zemveliso, zinokusebenza ngesiqhelo.

3, Ibhodi yeBhodi ye-PCB yeyona nto ithambekele kwiingxaki ekuvelisweni kwale bhodi yebhodi yesekethe, kwaye luluhlu oluphambili oluchaphazela ukudilizwa. Esona sigquthelo sikhulu se-tin ye-tiction i-tiction ilula yokuphelelwa yi-oxidation (zombini i-oxidation), i-deling), ibrawuza engalunganga, eya kuthi ikhokelele ekuphumezeni umbane ohluphekayo okanye ukungazinzi komsebenzi wonke webhodi.

I-4, iBhodi yeSekethi ye-PCB emqhubi iya kuba nezinto ezahlukeneyo zokuhambisa umqondiso, xa iphucula ireyithi yayo yothumelo kwaye kufuneka iphazamiseke, kuya kubangela ukuba i-Ettick iguqukele, ke kufuneka ulawule ixabiso lokufumana.
