MuPCBA kugadzirisa nekugadzira, pane zvinhu zvakawanda zvinokanganisa kunaka kweSMT welding, sePCB, zvigadzirwa zvemagetsi, kana solder paste, zvishandiso uye mamwe matambudziko chero kupi zvichakanganisa kunaka kweSMT welding, ipapo PCB yepasi pekurapa maitiro ichave. zvine chekuita nei pamhando yeSMT welding?

PCB pamusoro pekurapa maitiro anonyanya kusanganisira OSP, yemagetsi goridhe plating, kupfapfaidza tin / dip tin, goridhe / sirivha, nezvimwewo, iyo chaiyo sarudzo yeiyi maitiro inoda kutariswa zvinoenderana nechaiyo chigadzirwa chinodiwa, PCB yepasi kurapwa idanho rakakosha rekuita. muPCB yekugadzira maitiro, kunyanya kuwedzera welding kuvimbika uye anti-corrosion uye anti-oxidation basa, saka, PCB pamusoro pekurapa maitiro ndiyo zvakare chinhu chikuru chinokanganisa kunaka kwewelding!

Kana pane dambudziko nePCB surface treatment process, zvino inotanga kutungamirira kune oxidation kana kusvibiswa kwejojo ​​ye solder, iyo inobata zvakananga kuvimbika kwehuputi, zvichiita kuti urombo husina kunaka, hunoteverwa nePCB surface treatment process ichakanganisawo. iyo mechanical properties yejoint solder, yakadai seyokuoma kwepamusoro yakanyanyisa, zvinozotungamirira nyore kune iyo solder joint inodonha kana solder joint kuputika.
