Nigute Uhitamo Surface Kurangiza Kubishushanyo bya PCB
Gusuzuma no Kugereranya
Hariho inama nyinshi zijyanye no kurangiza hejuru, nka sisitemu idafite HASL ifite ikibazo cyo kugira uburinganire buhoraho.Electrolytic Ni / Au ihenze rwose kandi niba zahabu nyinshi ishyizwe kuri padi, irashobora gutuma abagurisha bacika.Amabati yo kwibiza afite kwangirika nyuma yo guhura nubushyuhe bwinshi, nko muburyo bwo hejuru no hepfo PCBA yerekana ibintu, nibindi .. Itandukaniro ryubuso bwavuzwe haruguru rirangiye rikeneye kubimenya neza.Imbonerahamwe ikurikira irerekana isuzumabumenyi ryakunze gukoreshwa hejuru yubuso bwanditse bwumuzingo.
