1. I-weldment ine-weldability elungileyo
I-solderability ebizwa ngokuba yi-solderability ibhekisela ekusebenzeni kwe-alloy enokuthi yenze indibaniselwano efanelekileyo yezinto zetsimbi eziza kuxutywa kunye ne-solder kwiqondo lokushisa elifanelekileyo. Ayizizo zonke iintsimbi ezikwazi ukuwelda kakuhle. Ukuze kuphuculwe i-solderability, imilinganiselo efana nokufakwa kwe-tin yomhlabathi kunye nesilivere yesilivere ingasetyenziselwa ukuthintela i-oxidation yezinto eziphathekayo.
2. Gcina ubuso be-weldment bucocekile
Ukuze ufezekise ukudibanisa okulungileyo kwe-solder kunye ne-weldment, i-welding surface kufuneka igcinwe icocekile. Kwanakwi-weldments kunye ne-weldability elungileyo, ngenxa yokugcinwa okanye ukungcoliswa, iifilimu ze-oxide kunye namabala e-oyile anobungozi bokumanzisa anokuthi avele kumphezulu we-weldments. Qinisekisa ukuba ususe ifilimu engcolileyo ngaphambi kwe-welding, ngaphandle koko umgangatho we-welding awukwazi ukuqinisekiswa.
3. Sebenzisa i-flux efanelekileyo
Umsebenzi we-flux kukususa ifilimu ye-oxide ebusweni be-weldment. Iinkqubo ze-welding ezahlukeneyo kufuneka zikhethe ii-fluxes ezahlukeneyo. Xa udibanisa iimveliso ze-elektroniki ezichanekileyo ezifana neebhodi zesekethe eziprintiweyo, ukwenzela ukuba i-welding ithembeke kwaye izinzile, i-rosin-based flux idla ngokusetyenziswa.
4. I-weldment kufuneka ifudunyezwe kwiqondo lokushisa elifanelekileyo
Ukuba ukushisa kwe-soldering kuphantsi kakhulu, akuthandeki ekungeneni kwee-athomu ze-solder, kwaye akunakwenzeka ukwenza i-alloy, kwaye kulula ukwenza i-joint virtual; ukuba ukushisa kwe-soldering kuphezulu kakhulu, i-solder iya kuba kwimeko engekho-eutectic, eya kukhawulezisa ukubola kunye nokuguqulwa kwe-flux, kunye nokunciphisa umgangatho we-solder. Kuya kubangela ukuba iipads kwibhodi yesekethe eprintiweyo ziphume.
5. Ixesha elifanelekileyo le-welding
Ixesha le-welding libhekisela kwixesha elifunekayo lokutshintsha komzimba kunye neekhemikhali ngexesha lenkqubo ye-welding. Xa ubushushu be-welding buchongiwe, ixesha elifanelekileyo le-welding kufuneka limiselwe ngokwemilo, indalo, kunye neempawu ze-workpiece ukuba idityaniswe. Ukuba ixesha le-welding lide kakhulu, amacandelo okanye iinxalenye ze-welding ziya konakala lula; ukuba imfutshane kakhulu, iimfuno ze-welding aziyi kufezekiswa. Ngokubanzi, elona xesha lide lokuwelda kwindawo nganye alikho ngaphezulu kwe-5s.
