Ukuhlaziywa kwezizathu ezintathu eziyinhloko zokwenqatshwa kwe-PCB
I-PCB wire yethusi iyawa (evame ukubizwa ngokuthi ukulahla ithusi). Izimboni ze-PCB zonke zithi yinkinga ye-laminate futhi idinga ukuthi izimboni zabo zokukhiqiza zithwale ukulahlekelwa okubi. 1. I-foil yethusi ibhalwe ngokweqile. Ucwecwe lwethusi lwe-electrolytic olusetshenziswa emakethe ngokuvamile luyi-singl...Funda kabanzi -
Imigomo nezincazelo zemboni ye-PCB: i-DIP ne-SIP
Iphakheji ye-Dual in-line (DIP) Iphakheji ye-Dual-in-line (i-DIP—iphakheji ekabili-emgqeni), ifomu lephakheji lezingxenye. Imigqa emibili yokuhola isuka ohlangothini lwedivayisi futhi ikuma-engeli angakwesokudla ukuya endizeni ehambisana nomzimba wengxenye.
