1. The weldment e na le weldability e ntle
Seo ho thoeng ke solderability se bolela ts'ebetso ea alloy e ka etsang motsoako o motle oa lisebelisoa tsa tšepe tse lokelang ho kenngoa le solder ka mocheso o loketseng.Ha se litšepe tsohle tse nang le weldability e ntle.E le ho ntlafatsa solderability, mehato e kang holim'a tin plating le silevera plating ka sebelisoa ho thibela lintho tse bonahalang holim oxidation.
2. Boloka bokaholimo ba weldment bo hloekile
E le ho finyella motsoako o motle oa solder le weldment, sebaka sa welding se tlameha ho bolokoa se hloekile.Esita le bakeng sa li-welld tse nang le weldability e ntle, ka lebaka la ho boloka kapa ho silafatsoa, lifilimi tsa oxide le litšila tsa oli tse kotsi ho kolobisa li ka 'na tsa etsahala holim'a li-weldments.Etsa bonnete ba hore o tlosa filimi e litšila pele o kenya tjheseletsa, ho seng joalo boleng ba welding bo ke ke ba tiisetsoa.
3. Sebelisa phallo e loketseng
Mosebetsi oa ho phalla ke ho tlosa filimi ea oxide holim'a holim'a weldment.Mekhoa e fapaneng ea welding e lokela ho khetha mefuta e fapaneng ea li-fluxes.Ha ho tjheseletsa lihlahisoa tsa elektroniki tse nepahetseng joalo ka liboto tsa potoloho tse hatisitsoeng, molemong oa ho etsa hore welding e ts'ehehe ebile e tsitsitse, hangata ho sebelisoa flux e thehiloeng ho rosin.
4. The weldment e lokela ho futhumatsoa ho mocheso o loketseng
Haeba mocheso oa soldering o le tlase haholo, ha o thabise ho kenella ha liathomo tsa solder, 'me ho ke ke ha khoneha ho etsa motsoako,' me ho bonolo ho theha motsoako oa sebele;haeba mocheso oa soldering o phahame haholo, solder e tla ba sebakeng se seng sa eutectic, se tla potlakisa ho senyeha le ho fetoha ha mocheso, le ho fokotsa boleng ba solder.E tla etsa hore mapheo a boto ea potoloho e hatisitsoeng a theohe.
5. Nako e loketseng ea ho cheselletsa
Nako ea welding e bolela nako e hlokahalang bakeng sa liphetoho tsa 'mele le lik'hemik'hale nakong ea ts'ebetso eohle ea welding.Ha mocheso oa tjheseletsa o khethiloe, nako e loketseng ea ho tjheseletsa e lokela ho khethoa ho latela sebopeho, tlhaho le litšobotsi tsa workpiece e lokelang ho chesetsoa.Haeba nako ea welding e le telele haholo, likarolo kapa likarolo tsa welding li tla senyeha habonolo;haeba e le khutšoanyane haholo, litlhoko tsa welding li ke ke tsa finyelloa.Ka kakaretso, nako e telele ka ho fetisisa ea ho cheselletsa sebaka ka seng ha e fete 5s.
