1. I-weldment inokushisela okuhle
Okubizwa ngokuthi i-solderability kubhekisela ekusebenzeni kwe-alloy engakha inhlanganisela enhle yezinto zensimbi okumele zishiswe kanye ne-solder ekushiseni okufanelekile.Akuzona zonke izinsimbi ezinokushisela okuhle.Ukuze kuthuthukiswe i-solderability, izinyathelo ezifana nokufakwa kwe-surface tin kanye ne-silver plating zingasetshenziswa ukuvimbela i-oxidation yezinto ezibonakalayo.
2. Gcina ingaphezulu le-weldment lihlanzekile
Ukuze kuzuzwe inhlanganisela enhle ye-solder kanye ne-weldment, indawo yokushisa kufanele igcinwe ihlanzekile.Ngisho nama-weldments ane-weldability enhle, ngenxa yokugcina noma ukungcola, amafilimu e-oxide namabala kawoyela ayingozi ekumanziseni angase avele ebusweni be-weldments.Qinisekisa ukuthi ususa ifilimu engcolile ngaphambi kokushisela, ngaphandle kwalokho ikhwalithi yokushisela ayikwazi ukuqinisekiswa.
3. Sebenzisa i-flux efanele
Umsebenzi we-flux ukususa ifilimu ye-oxide ebusweni be-weldment.Izinqubo ze-welding ezihlukene kufanele zikhethe ama-fluxes ahlukene.Lapho ushisela imikhiqizo ye-elekthronikhi enembile njengamabhodi wesekethe aphrintiwe, ukuze wenze ukushisela kuthembeke futhi kuzinzile, i-rosin-based flux ivame ukusetshenziswa.
4. I-weldment kufanele ishiselwe ekushiseni okufanelekile
Uma izinga lokushisa le-solder liphansi kakhulu, akulungile ukungena kwama-athomu e-solder, futhi akunakwenzeka ukwakha i-alloy, futhi kulula ukwakha ukuhlanganiswa okubonakalayo;uma izinga lokushisa le-solder liphezulu kakhulu, i-solder izoba sesimweni esingeyona i-eutectic, okuzosheshisa ukubola nokuguqulwa kwe-flux, futhi kunciphise izinga le-solder.Kuzokwenza ukuthi amaphedi ebhodini lesifunda eliphrintiwe aphume.
5. Isikhathi sokushisela esifanele
Isikhathi sokushisela sisho isikhathi esidingekayo sokushintsha ngokomzimba namakhemikhali phakathi nayo yonke inqubo yokushisela.Lapho izinga lokushisa lokushisela linqunywa, isikhathi esifanele sokushisela kufanele sinqunywe ngokuya ngokuma, imvelo, nezici ze-workpiece ezoshiselwa.Uma isikhathi se-welding side kakhulu, izingxenye noma izingxenye ze-welding zizolimala kalula;uma imfushane kakhulu, izidingo zokushisela ngeke zifezwe.Ngokuvamile, isikhathi eside kakhulu sokushisela indawo ngayinye asibi ngaphezu kwama-5s.
