Izici ezithinta ikhwalithi ye-reflow soldering yilezi ezilandelayo
1. Izici ezithonya zokunamathisela kwe-solder
Izinga le-reflow soldering lithinteka yizici eziningi.Isici esibaluleke kakhulu ijika lokushisa kwesithando somlilo sokugeleza kabusha kanye nemingcele yokubunjwa kwe-solder paste.Manje isithando somlilo esivamile sokugeleza kabusha se-welding sesikwazile ukulawula nokulungisa ijika lokushisa ngokunembile.Ngokuphambene, kumkhuba wokuminyana okuphezulu kanye ne-miniaturization, ukuphrinta kwe-solder paste sekuyisihluthulelo sokugeleza kabusha kwekhwalithi ye-solder.
Ukuma kwezinhlayiyana ze-solder paste alloy powder kuhlobene nekhwalithi yokushisela yamadivayisi wokuhlukanisa isikhala esincane, futhi i-viscosity kanye nokwakheka kwe-solder paste kufanele kukhethwe kahle.Ngaphezu kwalokho, i-solder paste ngokuvamile igcinwa endaweni ebandayo, futhi isembozo singavulwa kuphela lapho izinga lokushisa libuyiselwa ekamelweni lokushisa.Ukunakwa okukhethekile kufanele kukhokhwe ukugwema ukuxuba i-solder paste nomhwamuko wamanzi ngenxa yomehluko wokushisa.Uma kunesidingo, hlanganisa i-solder paste ne-mixer.
2. Umthelela wemishini yokushisela
Kwesinye isikhathi, ukudlidliza kwebhande le-conveyor le-reflow welding imishini nakho kungenye yezinto ezithinta ikhwalithi yokushisela.
3. Ithonya reflow welding inqubo
Ngemuva kokuqeda ikhwalithi engavamile yenqubo yokuphrinta yokunamathisela kwe-solder nenqubo ye-SMT, inqubo yokuphinda i-reflow soldering ngokwayo izoholela kulokhu okungahambi kahle kwekhwalithi okulandelayo:
① Ekushiseleni okubandayo, izinga lokushisa lokugeleza kabusha liphansi noma isikhathi sendawo yokugeleza kabusha asanele.
② Izinga lokushisa endaweni yokushisa yangaphambili yobuhlalu bethayela likhuphuka ngokushesha kakhulu (ngokuvamile, ukuthambekela kokukhuphuka kwezinga lokushisa kungaphansi kwamadigri angu-3 ngomzuzwana).
③ Uma ibhodi lesifunda noma izingxenye zithintwa umswakama, kulula ukubangela ukuqhuma kwe-tin nokukhiqiza ithini eqhubekayo.
④ Ngokuvamile, izinga lokushisa endaweni yokupholisa lehla ngokushesha kakhulu (imvamisa, ukwehla kwezinga lokushisa kokwehla kokushisela kungaphansi kwamadigri angu-4 ngomzuzwana).
