Kev taw qhia txog kev saib xyuas ntawm cov lus qhia hluav taws xob soldering hlau
Ua ntej ua haujlwm vuam
Lub tshuab ntxhua khaub ncaws yuav tsum tau ntub dej ua ntej, thiab tom qab ntawd cov dej ntau dhau yuav tsum tau nyem tawm. Tsuas yog nyob rau hauv txoj kev no tuaj yeem tau txais cov txiaj ntsig zoo tshaj plaws. Yog tias koj siv daim txhuam cev tsis ntub dej, lub taub hau ntawm lub taub hau yuav raug puas tsuaj thiab lub taub hau hlau yuav tsis raug tinned.
Thaum ua haujlwm soldering, cov txheej txheem vuam hauv qab no tuaj yeem tiv thaiv cov hlua hlau los ntawm cov hlau thiab txo cov oxidation.
Tom qab ua haujlwm welding
Ua ntej kho qhov kub txog li 250 degree, tom qab ntawd ntxuav cov hlau nplaum thiab ntxiv txheej tshiab ntawm cov tin rau kev tiv thaiv. (Yog tias koj siv cov hlau tsis muaj qhov kub thiab txias, txiav tawm lub hwj chim ua ntej thiab cia qhov kub ntawm cov hlau taub hau poob me ntsis ua ntej siv cov tin.)
Sim siv qhov kub tsis tshua muaj vuam
Qhov kub thiab txias yuav ua kom cov oxidation ntawm cov hlau taub hau thiab txo lub neej ntawm cov hlau taub hau. Yog hais tias qhov kub ntawm qhov kub ntawm qhov kub tshaj 470 degree, nws cov oxidation tus nqi yog ob zaug ntawm 380 degree.
Tsis txhob siv ntau dhau
Thaum vuam, tsis txhob siv ntau lub zog, txwv tsis pub lub taub hau hlau yuav puas thiab deformed. Ntev npaum li lub taub hau hlau tuaj yeem tiv tauj rau qhov sib koom ua ke, cov cua sov tuaj yeem hloov mus. Tsis tas li ntawd, xaiv txoj cai soldering hlau taub kuj tuaj yeem pab hloov cov cua sov.
Nco ntsoov khaws cov hlau taub hau tinned
Qhov no tuaj yeem txo txoj hauv kev ntawm oxidation ntawm lub taub hau hlau thiab ua kom nws ruaj khov dua. Tom qab siv, qhov kub ntawm cov hlau taub hau yuav tsum tau qis me ntsis ua ntej ntxiv cov hlau tshiab, kom cov tin plating txheej muaj qhov zoo dua los tiv thaiv oxidation.
Khaws lub taub hau hlau kom huv si thiab tshem tawm oxide tam sim ntawd
Yog tias muaj cov oxide dub nyob rau ntawm qhov kawg ntawm cov hlau soldering, lub hau yuav tsis tau tinned thiab yuav tsum tau ntxuav tam sim ntawd. Thaum ntxuav, ua ntej kho qhov kub ntawm lub taub hau ntawm lub taub hau kom txog 250 degree, ces siv daim txhuam cev ntxuav los ntxuav lub taub hau, thiab tom qab ntawd siv cov tin. Rov ua qhov kev txiav txim kom txog thaum cov oxide raug tshem tawm.
Xaiv ib qho flux nrog kev ua haujlwm tsawg
Cov xov tooj ntawm tes los yog corrosive fluxes yuav ua rau kom corrosion ntawm cov hlau taub hau thaum rhuab, yog li tsis tshua muaj corrosive fluxes yuav tsum tau xaiv.
Muab cov hlau nplaum tso rau ntawm qhov muag muag
Thaum cov hlau tsis xav tau, cov hlau nplaum yuav tsum tau ua tib zoo muab tso rau ntawm cov hlau uas tsim nyog los tiv thaiv cov hlau taub hau los ntawm kev sib tsoo.
Xaiv txoj cai soldering tswv yim
Xaiv qhov loj thiab cov duab ntawm lub taub hau yog qhov tseem ceeb heev. Kev xaiv cov lus qhia zoo tuaj yeem ua rau kev ua haujlwm zoo dua thiab ua kom lub zog ntawm lub taub. Xaiv qhov tsis ncaj ncees lawm txoj hlua hlau yuav tiv thaiv cov hlau soldering los ntawm kev ua haujlwm ntawm nws qhov ua tau zoo tshaj plaws, thiab qhov vuam zoo kuj yuav raug txo.
