I-soldering ingenye yezingxenye ezibaluleke kakhulu zenqubo yomhlangano we-electronics kubakhiqizi be-pcb.Uma kungekho ukuqinisekiswa kwekhwalithi ehambisanayo yenqubo ye-soldering, noma yikuphi umshini we-elekthronikhi oklanywe kahle uzoba nzima ukufeza imigomo yokuklama.Ngakho-ke, ngesikhathi se-welding, le misebenzi elandelayo kufanele yenziwe:
1. Noma ngabe ukushisela kuhle, indawo yokushisela kufanele igcinwe ihlanzekile.
Ngenxa yokugcina isikhathi eside nokungcola, amafilimu e-oxide ayingozi, amabala kawoyela, njll. angase akhiqizwe ebusweni bama-solder pads.Ngakho-ke, indawo engaphezulu kufanele ihlanzwe ngaphambi kwe-welding, ngaphandle kwalokho kunzima ukuqinisekisa ikhwalithi.
2. Izinga lokushisa kanye nesikhathi sokushisela kufanele kube ngokufanele.
Uma i-solder iyiyunifomu, i-solder ne-solder metal ishiswa ekushiseni kwe-solder ukuze i-solder encibilikisiwe icwiliswe futhi isakazeke ebusweni bensimbi ye-solder futhi yakhe inhlanganisela yensimbi.Ngakho-ke, ukuze kuqinisekiswe ukuhlangana okuqinile kwe-solder, kuyadingeka ukuba nokushisa okufanelekile kwe-solder.Emazingeni okushisa aphakeme ngokwanele, i-solder ingamanziswa futhi isakazwe ukuze yakhe ungqimba lwe-alloy.Izinga lokushisa liphezulu kakhulu ukuthi lingafakwa i-solder.Isikhathi se-soldering sinethonya elikhulu ku-solder, ukumanzisa kwezingxenye ezidayisiwe kanye nokwakhiwa kwesendlalelo sesibopho.Ukukwazi kahle isikhathi sokushisela kuyisihluthulelo sekhwalithi ephezulu yokushisela.
3. Amalunga e-solder kumele abe namandla anele okusebenza.
Ukuze kuqinisekiswe ukuthi izingxenye ezishiselwe ngeke ziwe futhi zikhululeke ngaphansi kokudlidliza noma umthelela, kuyadingeka ukuba namandla okwanele okusebenza kwamajoyini e-solder.Ukuze wenze amajoyinti e-solder abe namandla anele emishini, indlela yokugoba amatheminali okuhola ezingxenye ezidayisiwe ingasetshenziswa ngokuvamile, kodwa i-solder ngokweqile akufanele iqoqwe, okungenzeka ibangele izifunda ezimfushane phakathi kwe-soldering ebonakalayo kanye nezifunda ezimfushane.Amalunga e-solder namajoyinti e-solder.
4. I-Welding kufanele ithembeke futhi iqinisekise ukuqhutshwa kukagesi.
Ukuze wenze amalunga e-solder abe ne-conductivity enhle, kuyadingeka ukuvimbela i-solder yamanga.I-Welding isho ukuthi asikho isakhiwo se-alloy phakathi kwe-solder ne-solder surface, kodwa imane inamathele endaweni yensimbi edayisiwe.E-welding, uma kwakhiwa ingxenye ye-alloy kuphela futhi enye ingakakhiwa, i-solder joint nayo ingadlula okwamanje ngesikhathi esifushane, futhi kunzima ukuthola izinkinga ngethuluzi.Kodwa-ke, njengoba isikhathi sihamba, indawo engenzi i-alloy izobe ifakwe i-oxidized, okuzoholela esimweni sokuvulwa nokuphuka kwesikhathi, okuzobangela izinkinga zekhwalithi zomkhiqizo nakanjani.
Ngamafuphi, ukuhlanganiswa okuhle kwe-solder kufanele kube: i-solder joint ikhanya futhi ibushelelezi;ungqimba lwe-solder lufana, luncane, lufanele ubukhulu bephedi, futhi uhlaka lwe-joint lufiphalisiwe;i-solder yanele futhi isakazeka esimweni sesiketi;akukho mifantu, izimbobo, Azikho izinsalela ze-flux.
