Ngikholwa ukuthi abangani abaningi bazobambeka kakhulu lapho bekhetha i-reflow soldering.Abazi ukuthi bangakhetha kanjani, ikakhulukazi abangani abangazi i-reflow soldering badidekile nakakhulu.Ungakhathazeki manje.Ake sethule kafushane ukuthi kwenziwa kanjani.Khetha indlela ye-reflow soldering:
1. Hlola ukusebenza kwe-insulation ye-ovini yokugeleza kabusha.
I-ovini yokugeleza kabusha yekhwalithi ephezulu inomphumela omuhle wokulondoloza ukushisa nokusebenza kahle kokushisa okuphezulu, kodwa i-ovini yokugeleza kabusha engaphansi ayinawo umsebenzi onjalo.Nakuba ukusebenza kahle okushisayo kwehhavini lokugeleza kabusha kunzima ukukukala, ungathinta ihhavini lokugeleza kabusha kanye nomoya wokukhipha umoya ngesandla.Lapho ipayipi lisebenza, igobolondo lisetshenziselwa ukwahlulela izinga lokushisa.Uma uzizwa kushisa uma uyithinta ngezandla zakho noma ungalokothi uyithinte, kusho ukuthi ukusebenza kokushisa kwesithando somlilo kubi futhi ukusetshenziswa kwamandla kukhulu.Ngokuvamile, isandla somuntu sizizwa sishisa kancane (cishe ama-degree Celsius angama-50).
2. Uhlobo lwe-heater: Izifudumezi zingahlukaniswa zibe izibani ze-infrared nama-adaptive lamp heater.
(1) I-heater ye-Tubular: Inezinzuzo zokushisa okuphezulu okusebenzayo, ubude be-radiation emifushane kanye nokusabela kokushisa okusheshayo.Kodwa-ke, ngenxa yokukhiqizwa kokukhanya ngesikhathi sokushisa, kunemiphumela ehlukile yokubonisa ezingxenyeni zokushisela zemibala ehlukene.Ngesikhathi esifanayo, ayifuni Ilungele ukufanisa nomoya oshisayo ophoqelelwe.
(2) I-heater yepuleti: Ukusabela okushisayo kuhamba kancane futhi ukusebenza kahle kuphansi kancane.Kodwa-ke, ngenxa ye-inertia enkulu yokushisa, ukubhoboza kuhambisana nokushisa komoya oshisayo.Ayizweli kancane kumbala wezingxenye ezishiselwe futhi inomphumela omncane wesithunzi.Ngaphezu kwalokho, okwamanje athengiswa Kuhhavini ogelezayo, ama-heaters cishe wonke amapuleti e-aluminium noma ama-heaters ensimbi engagqwali.
3. Isistimu yokudlulisa ukushisa ye-reflow soldering kufanele ibe nezindawo zokushisa ezi-4 kuya kwezi-5.
I-reflow soldering enhle ine-heater okungenani endaweni yokushisa kuqala, futhi ingalawula ngokuzimela izinga lokushisa ukuze kuqinisekiswe ukuthi izinga lokushisa lingadluliselwa ngokushesha ekushiseni kwe-solder ngezindlela ezintathu: i-convection, i-convection, ne-radiation.
Amaphuzu angenhla amayelana nendlela yokugeleza kabusha kwe-soldering.Uma sikhetha i-reflow soldering, singaqhathanisa ngokusho kwamaphuzu angenhla.Ngesikhathi esifanayo, sidinga futhi ukukhetha ukuthi yiluphi uhlobo lwe-reflow soldering ngokuvumelana nezidingo zethu.Ngethemba ukuthi ingasiza wonke umuntu.
