Imingcele yenqubo eyinhloko yereflow soldering imishiniukudlulisa ukushisa, ukulawula isivinini seketango kanye nesivinini somoya kanye nokulawula umthamo womoya.
1. Ukulawulwa kokudluliswa kokushisa ngaphakathii-soldering oven.
Njengamanje, imikhiqizo eminingi isebenzisa ubuchwepheshe obungenawo umthofu, ngakho-kereflow soldering umshiniesetshenziswa manje ikakhulukazi umoya oshisayoi-reflow soldering.Enkambweni ye-solder-free soldering, kuyadingeka ukunaka umphumela wokudlulisa ukushisa nokusebenza kahle kokushintshanisa ukushisa.Ikakhulukazi ezingxenyeni ezinomthamo omkhulu wokushisa, uma ukudluliswa kokushisa okwanele nokushintshaniswa akukwazi ukutholwa, izinga lokushisa liyoba liphansi kakhulu kunelamadivayisi anamandla amancane okushisa, okuholela ekuhlukeni kokushisa kwe-lateral..Imodi yokugeleza komoya ye-reflow oven body ithinta ngqo isivinini sokushintshana kokushisa.Izindlela ezimbili zokudluliswa komoya oshisayo zokuthuthwa kwe-reflow soldering yilezi: indlela yokudlulisa umoya oshisayo we-micro-circulation, kanti enye ibizwa ngokuthi indlela yokudlulisa umoya oshisayo.
2. Ukulawulwa kwejubane le-chain ofi-reflow soldering.
Ukulawulwa kwejubane leketango lemishini yokuphinda kufakwe i-solder kuzothinta umehluko wokushisa ongasemuva webhodi lesifunda.Ngokuvamile, ukunciphisa isivinini seketango kuzonikeza idivayisi enamandla amakhulu okushisa isikhathi esengeziwe sokushisa, ngaleyo ndlela kunciphise umehluko wokushisa osemaceleni.Kodwa emva kwakho konke, ukulungiselelwa kwejika lokushisa kwesithando somlilo kuncike ezidingweni ze-solder paste, ngakho-ke kungenangqondo ukunciphisa isivinini seketanga ngaphandle komkhawulo ekukhiqizeni kwangempela.
3. Ukulawulwa kwesivinini somoya kanye nomthamo womoya wemishini yokudambisa yokugeleza kabusha.
Gcina ezinye izimo ku-reflow oveningashintshiwe futhi inciphisa kuphela ijubane labalandeli kuhhavini lokugeleza kabusha ngo-30%, izinga lokushisa ebhodini lesifunda lizokwehla cishe ngama-degree angu-10.Kungabonakala ukuthi ukulawulwa kwesivinini somoya kanye nevolumu yomoya kubalulekile ekushiseni ukulawulwa kwezinga lokushisa.
Ukuze ukwazi ukulawula isivinini somoya kanye nevolumu yomoya, amaphuzu amabili adinga ukunakwa:
a.Isivinini se-fan kufanele silawulwe ukuguqulwa kwefrikhwensi ukuze kuncishiswe ithonya lokushintshashintsha kwe-voltage kuyo;
b.Nciphisa umthamo womoya wokukhipha imishini, ngoba umthwalo ophakathi wokukhipha umoya uvame ukungazinzi, okuthinta kalula ukuhamba komoya oshisayo esithandweni somlilo.
