I-PCBA circuit board welding disc inkinga emnyama iyinkinga evamile yebhodi lesifunda, okuholela ku-PCBA welding disc emnyama ngezizathu eziningi, kodwa ngokuvamile okubangelwa izizathu ezilandelayo:

I-1, i-pad oxidation: Uma i-PCBA pad ibonakala kumswakama isikhathi eside, izobangela ukuthi ingaphezulu lephedi lifake i-oxidize, lenze ifilimu ye-oxide ebusweni be-pad, okuholela ekubeni mnyama, ngakho-ke, lapho ugcina i-PCBA, ukunakwa kufanele kukhokhwe ekugcineni imvelo yomile, futhi ngesikhathi esifanayo, i-PCBA kufanele ifakwe vacuum ngesikhathi ukugwema ukuchayeka isikhathi eside emoyeni!

2, izinkinga zenqubo yokushisela: ku-reflow welding noma i-wave soldering, uma izinga lokushisa lokushisela liphezulu kakhulu noma isikhathi sokushisela siside kakhulu, kuzophinde kuholele ku-oxidation ye-welding pad black phenomenon, lokhu kusabela kuvame ukubangelwa ukushisela. izinga lokushisa lidlula izinga lokushisa elinconywayo le-solder, okuholela ekusheshisweni kwenqubo ye-oxidation, ngakho-ke inqubo ye-welding kumele ihambisane nemigomo yokusebenza ye-welding!

I-3, inkinga ye-solder: i-solder ngokuvamile ibhekisela ku-solder unamathisele, ithini, ikhwalithi ye-solder yinhle noma imbi, uma ukusetshenziswa kwe-solder empofu, kuzokwenza ukuthi i-solder in the izinto eziyingozi nokungcola ikhishwe, okuholela ku-pad emnyama, ngakho-ke, ekukhethweni kwe-solder, kufanele sigweme ukusetshenziswa kwe-solder esezingeni eliphansi!

I-4, izinkinga zokuhlanza: Ngokuvamile, esimweni sokusetshenziswa kwe-flux kuyadingeka ukuhlanza ibhodi, ukuze kukhishwe insalela ye-flux ku-pad, futhi uma insalela ye-flux ingasuswa ngokugcwele, khona-ke lezi zinsalela zingase zinciphise. noma i-carbonize emazingeni okushisa aphezulu, ukuze i-pad ibonakale imnyama. Ngakho-ke, ukuhlanza okufika ngesikhathi ngemuva kwe-welding kuyadingeka kakhulu!

I-5, izinkinga zengxenye: uma ikhwalithi yezingxenye ze-elekthronikhi ingeyinhle, noma impahla yephinikhodi yengxenye ingalungile, ingase iholele esimweni se-black welding disc, ngakho-ke, lapho sikhetha izingxenye ze-elekthronikhi, kufanele sikhethe izinga elihle. izingxenye zokuqinisekisa ukuthi ikhwalithi yokugqoka kanye nempahla yephini yezingxenye iyafaneleka.

Lokhu okungenhla kuyisizathu esiyinhloko se-PCBA welding tray emnyama, futhi ngokwezizathu ezahlukene, singakhetha futhi izinyathelo zokuthuthukisa ezihambisanayo, ukuze sinciphise ngempumelelo inkinga ye-PCBA welding tray emnyama, ukuthuthukisa ikhwalithi yemikhiqizo!
