Pane nzira mbiri huru dzekutengesa kutengeserana - reflow uye wave soldering.
Wave soldering inosanganisira kupfuura solder pamwe nebhodhi rinopisa.Bhodhi tembiricha, kudziyisa uye kutonhora profiles (asiri-mutsara), soldering tembiricha, waveform (yunifomu), solder nguva, kuyerera mwero, bhodhi velocity, nezvimwe zvinhu zvese zvakakosha zvinokanganisa mhedzisiro.Zvose zvikamu zvekugadzirwa kwebhodhi, marongerwo, chimiro chepedhi uye ukuru, kupisa kupisa, nezvimwewo zvinoda kunyatsotariswa kuitira zvakanaka soldering migumisiro.
Zviripachena kuti wave soldering inzira ine hukasha uye inodakadza - saka sei uchishandisa nzira iyi zvachose?
Inoshandiswa nekuti ndiyo yakanakisa uye yakachipa nzira inowanikwa, uye mune dzimwe nguva nzira inoshanda chete.Iko kuburikidza ne-gomba zvikamu zvinoshandiswa, wave soldering inowanzova nzira yekusarudza.
Reflow soldering inoreva kushandiswa kwe solder paste (musanganiswa we solder uye flux) kubatanidza chimwe kana zvimwe zvinhu zvemagetsi kune ekusangana pads, uye kunyungudutsa solder kuburikidza nekudzora kupisa kuti uwane chisungo chisingaperi.Reflow ovens inogona kushandiswa , infrared heat mwenje kana kupisa pfuti uye dzimwe nzira dzekudziya dzekupisa.Reflow soldering ine zvishoma zvinodiwa pane pad shape, shading, board orientation, tembiricha profile (ichiri yakakosha), zvichingodaro. Pamusoro pezvikamu zvekukwira pamusoro, kazhinji isarudzo yakanaka kwazvo - musanganiswa we solder uye flux unoiswa kare ne stencil kana imwe. automated process, uye zvikamu zvinoiswa panzvimbo uye zvinowanzobatwa munzvimbo ne solder paste.Adhesives inogona kushandiswa mumamiriro ezvinhu anoda, asi haana kukodzera ne-by-hole parts - kazhinji reflow haisi iyo nzira yekusarudza kuburikidza ne-hole parts.Mapuranga eComposite kana akakwirira-density anogona kushandisa musanganiswa we reflow uye wave soldering, ane zvikamu zvinotungamirirwa chete zvakasungirirwa kune rumwe rutivi rwePCB (inonzi side A), kuitira kuti inogona kuve yakatengeswa kune rumwe rutivi B. Apo chikamu cheTH chiri kuiswa kusati kwapinzwa chikamu cheburi-buri, chikamu chinogona kufambiswazve kudivi reA.Zvimwe zvikamu zveSMD zvinozowedzerwa kudivi reB kuti ritengeswe nezvikamu zveTH.Avo vanoshuvira pawaya yakakwira solder vanogona kuedza musanganiswa wakaomesesa weakasiyana ekunyunguduka vatengesi, vachibvumira divi B reflow risati rasvika kana mushure mekutengesa kwemafungu, asi izvi hazviwanzo.
Reflow soldering tekinoroji inoshandiswa kune pamusoro pegomo zvikamu.Nepo mazhinji epamusoro pegomo redunhu mabhodhi anogona kuunganidzwa nemaoko uchishandisa solder iron uye solder waya, maitiro anononoka uye mhedzisiro bhodhi inogona kusavimbika.Midziyo yemazuva ano PCB yegungano inoshandisa reflow soldering yakanangana nekugadzirwa kwakawanda, uko michina yekutora-uye-nzvimbo inoisa zvikamu pamabhodhi, akaputirwa nesolder paste, uye maitiro ese anongoitwa otomatiki.
