Dab tsi yog vim li cas hluav taws xob soldering hlau taub hau tsis noj tin
Qhov zoo ntawm hluav taws xob soldering hlau taub hau ncaj qha cuam tshuam rau vuam zoo. Muaj ntau qhov laj thawj vim li cas lub taub hau hluav taws xob siv hluav taws xob tsis noj tin.
1. Tsis zoo ntawm soldering hlau taub
Yav dhau los feem ntau siv pheej yig sab hauv cov cua sov uas tsis muaj zog hluav taws xob soldering hlau. Lub taub hau ntawm lub tshuab hluav taws xob hluav taws xob sab hauv no yog ua los ntawm tooj liab thiab tsis tuaj yeem hloov kho rau qhov kub thiab txias vim tsis muaj qhov kub thiab txias. Tom qab tau muab lub zog rau ib lub sijhawm, qhov kub ntawm lub taub hau soldering yuav siab dua thiab siab dua. Thaum kub kub, tooj liab soldering taub hau yog nquag oxidation thiab blackening. Yog tias lub taub hau yog polished nrog cov ntawv xuab zeb lossis cov ntaub ntawv, nws tseem yuav oxidize thiab blacken tom qab ib pliag. Yog li ntawd, yog tias siv cov hlau nplaum pheej yig uas tau hais los saum toj no ua rau lub taub hau oxidize thiab blacken thiab tsis noj tin, nws raug nquahu kom hloov cov hlau soldering. Nws yog qhov zoo tshaj plaws los xaiv qhov ntsuas kub tsis tu ncua lossis kho qhov kub thiab txias soldering hlau.
936 adjustable kub hluav taws xob soldering hlau tshwj xeeb soldering hlau taub.
Lub taub hau ntawm no 936 adjustable kub hluav taws xob soldering hlau tuaj yeem hloov tau thiab muaj ntau yam duab, uas tuaj yeem xaiv raws li kev xav tau vuam. Hom soldering hlau taub hau no yog ua los ntawm cov khoom siv alloy thiab tsis yooj yim oxidized ntawm qhov kub thiab txias. Tsuav lub taub hau hlau tsis corroded los ntawm acidic soldering flux, thiab tsis tas yuav tsum tau kub melted kua nplaum los yog yas, lub taub hau hlau soldering yog yooj yim rau tin.
2. Siv acidic flux lossis soldering hlau nrog ntau impurities
Acid flux.
Qee cov neeg pib tshiab hauv hluav taws xob nyiam siv cov kua qaub solder paste ua cov kua nplaum thaum vuam. Hom flux no yog me ntsis acidic thiab me ntsis corrosive rau qee cov lus qhia tsis zoo soldering hlau. Nws raug nquahu kom siv blocky rosin lossis rosin cawv tov ua flux thaum vuam. Tsis tas li ntawd, qee qhov pheej yig soldering hlau muaj ntau cov impurities, thiab siv hom soldering hlau no tuaj yeem ua rau lub taub hau hlau tsis txhob noj tin. Vim tias qhov tsis zoo ntawm cov dej tsis zoo thiab cov dej ntws tawm ntawm cov hlau nplaum no tom qab melting, nws cov pob qij txha ua tsaus thiab tsis du thiab ci. Yog hais tias qhov tsis zoo ntawm cov hlau soldering ua rau lub taub hau ntawm lub taub hau kom tsis txhob noj cov tin, nws raug nquahu kom xaiv qhov zoo tshaj plaws melting qhov chaw vuam hlau thaum vuam.
