PCB yana nufin allon da'ira da aka buga, wanda shine mai ba da haɗin wutar lantarki na kayan lantarki.Yana da yawa a cikin masana'antar lantarki, kuma ana amfani da suturar conformal kuma ana amfani dashi sosai.Babu wani manne na PCB guda uku manne (fenti).A gaskiya ma, shine a yi amfani da Layer na suturar da aka dace akan PCB.
Conformal shafi kayan ne don hana PCB daga lalacewa ta waje dalilai da kuma inganta sabis rayuwa na PCB.Kamar yadda samfuran lantarki masu tsayi suna da buƙatu mafi girma kuma mafi girma don ingancin PCB, ana amfani da fenti mai tabbatarwa guda uku akan allunan kewayawa.
Abubuwan da ke iya haifar da lalacewar PCB:

Yadda ake amfani da sauri da ingancim shafiku PCB?
A cikin PCB masana'antu masana'antu, akwai cikakken atomatik kayan aiki sadaukar da shafi kariya Paint ga kewaye allon -conformal shafi inji, kuma aka sani da uku hujja Paint shafi inji, uku hujja Paint spraying inji, uku hujja fenti spraying inji, uku hujja Paint spraying. inji, da dai sauransu, wanda aka sadaukar domin sarrafa ruwa da kuma rufe wani Layer na uku hujja fenti a saman PCB, kamar rufe Layer na photoresist a saman PCB ta impregnation, fesa ko spin shafi.
