Yuav tsum tau rau phau ntawv soldering ntawm qhov kub ntawm hluav taws xob soldering hlau
txheej txheem vuam
1 Ua kom sov thiab npaj
Ua ntej lub soldering ua hauj lwm, nws yog ib qhov tsim nyog yuav tau preheat hluav taws xob soldering hlau los pab txhawb txoj kev vam meej ntawm cov kauj ruam tom ntej. Nyob rau tib lub sijhawm, siv cov flux tshem tawm cov oxides ntawm qhov kawg ntawm cov hlau soldering, kom lub hau ntawm cov hlau tuaj yeem ncav cuag lub xeev huv tshaj plaws, thiab tom qab ntawd tinned. Qhov kub ntawm cov hlau taub hau tuaj yeem kis tau sai dua, thiab qhov zoo tshaj plaws vuam nyhuv tuaj yeem ua tiav. Tom qab ntawd tuav lub vuam hlau nyob rau hauv koj sab tes laug, tuav lub vuam hlau ruaj khov nrog koj sab tes xis, thiab pib npaj.
2 Cua sov lub vuam
Muab lub taub hau ntawm cov hlau nplaum tiv thaiv kev sib tshuam ntawm ob qhov chaw yuav tsum tau welded (qhov kev sib txuas ntawm lub ncoo thiab cov hlau lead ntawm cov khoom), thiab cov welded ib feem yuav rhuab.
3 Pub tin hlau
Thaum lub vuam nto ntawm lub welded daim yog rhuab mus rau ib tug tej yam kub, lub solder hlau hu rau lub welded daim los ntawm lub opposite sab ntawm lub soldering hlau. Lus Cim: Tsis txhob xa cov xov hlau mus rau qhov kawg ntawm cov hlau soldering!
4 Tshem cov hlau
Thaum ib tug npaum li cas ntawm solder yog melted ntawm qhov kev twb kev txuas, tam sim ntawd tshem tawm cov tin hlau nyob rau hauv ib tug upward 45 degree kev taw qhia.
(5) Tshem tawm cov hlau soldering
Tom qab lub solder infiltrates lub vuam ncoo thiab lub soldering ib feem ntawm lub weldment, upward
Tshem cov hlau nplaum tawm ntawm 45 degree.
2 Kev tsim cov txheej txheem ntawm cov pob qij txha
(1) Thaum cov khoom yuav tsum tau welded thiab solder hlau yog rhuab mus rau lub melting point ntawm rosin, uas yog 172 degree rau 173 degree, lub abietic acid nyob rau hauv lub rosin pib tshem tawm cov nto oxide ntawm cov khoom yuav tsum tau welded, thiab nyob rau tib lub sij hawm txo qhov nro ntawm cov khoom yuav tsum tau welded, muab kev tsim ntawm cov pob qij txha. Thaum tshav kub kub conduction thiab txhim kho solder fluidity.
(2) Raws li qhov kub thiab txias ntxiv, cov hlau nplaum pib yaj, thiab nyob rau hauv qhov kev txiav txim ntawm cov flux, lub melted solder diffuses raws cov pob zoo thiab cov khoom siv lead ua rau ntawm qhov chaw ntawm cov khoom yuav tsum tau soldered, thiab ua raws li cov khoom siv. Yam khoom yuav tsum tau soldered Nto, kom cov hlau atoms ntawm lub solder thiab cov khoom yuav tsum tau soldered nyob ze rau ib leeg.
(3) Thaum qhov kub thiab txias nce ntxiv, kev ua haujlwm ntawm cov hlau atoms intensifies, kom cov hlau atoms ntawm solder thiab cov khoom yuav tsum tau soldered diffuse ib leeg, nkag mus rau hauv lub lattice lattice ntawm lwm tus neeg, thiab tsim ib tug hlau compound ntawm solder thiab cov khoom yuav tsum tau soldered, thiab hu ua alloy txheej.
(4) Thaum qhov kub qis dua 300 degree, rosin tsis tau decomposed nrog charcoal
Ua ntej melting, lub tshav kub yuav tsum tau muab tshem tawm, thiab lub solder sib koom yuav tsum tau txias lawm los tsim cov pob qij txha.
3 Yam cuam tshuam rau vuam
Raws li cov saum toj no (1) thiab (2), yam cuam tshuam rau vuam muaj xws li tus neeg teb xov tooj, cov khoom yuav tsum tau welded, solder hlau, flux thiab hluav taws xob soldering hlau, thiab lwm yam, thiab lawv cov dej num raws li nram no.
(1) Tus neeg teb xov tooj: Tswj lub sijhawm vuam, tus tswv ntawm vuam.
(2) Cov khoom yuav tsum tau welded: cov khoom yuav tsum tau welded, uas muab ib tug cab kuj rau welding, thiab muaj feem xyuam rau nws tus kheej weldability thiab tshav kub muaj peev xwm.
(3) solder hlau: Qhov nruab nrab uas txuas cov khoom yuav tsum tau soldered muaj feem xyuam rau nws tus kheej melting point.
(4) Flux: feem ntau rosin, uas tshem tawm oxides ntawm qhov chaw ntawm cov khoom siv soldered thiab txo qhov nro ntawm cov khoom siv.
(5) Soldering hlau: Muab cov khoom cua sov rau vuam.
Ntawm lawv, solder hlau thiab flux yog cov khoom sib xyaw nrog cov khoom ruaj khov, tshwj tsis yog qhov kev xaiv loj ntawm cov hlau xaim thaum siv, nws tsis tshua muaj kev cuam tshuam rau vuam. Qhov kub ntawm cov hluav taws xob soldering hlau feem ntau yog xaiv raws li lub melting point ntawm solder hlau thiab lub tshav kub muaj peev xwm ntawm cov khoom yuav tsum tau soldered.
