A PCBA aiki da kuma samar, akwai da yawa dalilai da shafi ingancin SMT waldi, kamar PCB, lantarki aka gyara, ko solder manna, kayan aiki da sauran matsaloli a kowane wuri zai shafi ingancin SMT waldi, sa'an nan PCB surface jiyya tsari zai. da abin da tasiri a kan ingancin SMT waldi?
PCB surface jiyya tsari yafi hada da OSP, lantarki zinariya plating, fesa tin / tsoma tin, zinariya / azurfa, da dai sauransu, da takamaiman zabi na abin da tsari bukatar da za a ƙaddara bisa ga ainihin samfurin bukatun, PCB surface jiyya ne mai muhimmanci tsari mataki mataki. a cikin PCB masana'antu tsari, yafi don ƙara waldi AMINCI da anti-lalata da anti-oxidation rawa, don haka, PCB surface jiyya tsari ne kuma babban factor shafi ingancin waldi!
Idan akwai matsala tare da PCB surface jiyya tsari, sa'an nan shi zai farko kai ga hadawan abu da iskar shaka ko gurɓata da solder hadin gwiwa, wanda kai tsaye rinjayar da AMINCI na waldi, haifar da matalauta waldi, bi da PCB surface jiyya tsari zai kuma shafi. kayan aikin injiniya na haɗin gwiwa na solder, kamar taurin saman ya yi yawa, zai iya haifar da haɗin gwiwa mai sauƙi don fadowa ko fashewar haɗin gwiwa.
