Ndiyakholelwa ukuba uninzi lwabahlobo luya kubanjiswa kakhulu xa ukhetha i-reflow soldering.Abayazi indlela yokukhetha, ngakumbi abahlobo abangaziyo i-reflow soldering babhideke ngakumbi.Sukuba nexhala ngoku.Makhe sazise ngokufutshane indlela yokwenza.Khetha indlela yokubuyisela kwakhona i-solder:
1. Jonga ukusebenza kwe-insulation ye-oven reflow.
I-oven ephezulu yokubuyisela ubushushu inesiphumo esihle sokugcina ubushushu kunye nokusebenza kakuhle kwe-thermal, kodwa i-oven ephantsi yokubuyisela ayinalo umsebenzi onjalo.Nangona ukusebenza kwe-thermal ye-oven yokubuyisela kunzima ukulinganisa, unokuchukumisa i-oven yokubuyisela kunye nokukhupha umoya ngesandla.Xa umbhobho usebenza, iqokobhe lisetyenziselwa ukugweba ubushushu.Ukuba uziva ushushu xa uyibamba ngezandla zakho okanye awufuni ukuyiphatha, oko kuthetha ukuba ukusebenza kwe-insulation yesithando somlilo kubi kwaye ukusetyenziswa kwamandla kukhulu.Ngokuqhelekileyo, isandla somntu sivakala sishushu kancinane (malunga nama-50 ngokukaCelsius).
2. Uhlobo lwe-heater: Izifudumezi zinokwahlulwa zibe zizibane ze-infrared kunye nezifudumezi zesibane eziguquguqukayo.
1Nangona kunjalo, ngenxa yesizukulwana sokukhanya ngexesha lokufudumeza, kuneempembelelo ezahlukeneyo zokubonisa kumacandelo e-welding yemibala eyahlukeneyo.Ngexesha elifanayo, ayenzi Ifanelekile ukuhambelana nomoya oshushu onyanzelekileyo.
(2) Isifudumezi seplate: Impendulo ye-thermal iyacotha kwaye ukusebenza kakuhle kuphantsi kancinane.Nangona kunjalo, ngenxa ye-inertia enkulu ye-thermal, i-perforation ilungele ukufudumeza komoya oshushu.Ayinabungozi kangako kumbala wamacandelo adibeneyo kwaye inomphumela omncinci wesithunzi.Ukongeza, ngoku kuthengiswa kwii-ovens zokufudumeza, izifudumezi ziphantse zonke iipleyiti ze-aluminium okanye izifudumezi zensimbi ezingenasici.
3. Inkqubo yokudlulisa ukushisa kwe-reflow soldering kufuneka ibe neendawo ezi-4 ukuya kwezi-5 zokufudumala.
I-soldering ye-reflow elungileyo ine-heater okungenani kwindawo yokufudumeza, kwaye inokulawula ngokuzimeleyo iqondo lobushushu ukuqinisekisa ukuba ubushushu bunokudluliselwa ngokukhawuleza kwiqondo lokushisa elithengiswayo ngeendlela ezintathu: i-convection, i-convection, kunye ne-radiation.
La manqaku angasentla amalunga nendlela yokuphinda uqukunjelwe i-soldering.Xa sikhetha i-reflow soldering, sinokuthelekisa ngokwala manqaku angentla.Kwangaxeshanye, kufuneka sikhethe ukuba luhlobo luni lwe-reflow soldering ngokweemfuno zethu.Ndiyathemba ukuba inokunceda wonke umntu.
