Yuav ua li cas nrog oxidised dub soldering hlau taub tsis muaj tin staining
Soldering hlau oxidation ua rau yog kev siv cov neeg tsis tau tuav lub taub hau hlau, yuav ua li cas nrog oxidation dub hlau taub hau, ua ntej ntawm tag nrho cov, siv ib rab riam rau cov dub txheej ntawm lub taub hau hlau scraped, kom txog rau thaum scraped tawm ntawm thawj xim. ntawm tooj liab daj, thiab ces ntxiv rosin ib tug solder rau nws. Nco ntsoov tsis txhob siv cov hlau thaum pem hauv ntej tag nrho ntawm cov solder, qhov no yog hu ua kev kho lub taub hau hlau. Nws yuav tsis tshwm sim oxidation dub.
Nrog ib rab riam los yog nplua gauze kom tshem tawm qhov saum npoo ntawm oxide txheej, thiab tom qab ntawd lub taub hau ntawm lub taub hau dipped nyob rau hauv rosin tag nrho ntawm solder ntawm txoj kab, xyuam xim rau kev siv cov txheej txheem rau lub sij hawm ntev tsis muaj nws, nws yog qhov zoo tshaj rau kev siv cov txheej txheem. kho qhov kub thiab txias los yog ncaj qha mus rau soldering hlau fais fab tuag.
Hloov lub ntsiab lus zoo ntawm lub taub hau hlau, lossis kev siv dag zog yog qhov tsis muaj txiaj ntsig, tau txais ntawm cov tin thiab tom qab ntawd oxidised tsis nplaum ncaws, ib txwm siv ua ntej ntawm rosin.
Kos nrog ib rab riam, dew dawb lub taub hau, dip me ntsis rosin, nyob rau hauv qhov sib ntxiv ntawm solder, nws yog zoo, tsis txhob siv lub soldering hlau, lub taub hau yuav tsum tau ntxiv rau lub solder burning, txwv tsis pub nws yuav tsis stained nrog tin.
Yuav ua li cas siv cov hlau soldering kom raug?
1, thawj lub ntsiab lus hais tias qhov flux no (flux paste) siv qhov teeb meem, feem ntau ntawm cov flux yog acidic flux, lub taub hau hlau soldering muaj qee yam oxidation, sim tsis txhob siv.
Ntawm no los qhia txog txoj hauv kev zoo dua los ua kom flux, uas yog, rosin crushed rau hauv cov hmoov, ncuav rau hauv cov kua dej cawv kom tag nrho cov kua. Qhov piv yog feem ntau 40% ntawm rosin hmoov ntxiv rau 60% cawv tov, rosin me ntsis ntxiv tsis yog teeb meem. Yuav tsum tau ua tib zoo saib xyuas kom tsis tuaj yeem siv cov cawv tshuaj kho mob, siv ntau tshaj 90% cawv tov, tib lub sij hawm lub thawv kom tswj tau lub xeev kaw.
2, qhov thib ob taw tes hais tias yog qhov teeb meem ntawm lub hwj chim no, ntau tus neeg koom tes me me tom qab siv tus cwj pwm tsis raug ncua sij hawm. Soldering hlau taub hau nyob rau hauv lub tshav kub lub xeev, lub ntuj oxidation ntawm tsis-stick solder. Yog li ntawd, kev siv txhua hnub yuav tsum tau ua, ua tiav hauv lub sijhawm txiav tawm lub zog hluav taws xob.
3, lub ntsiab lus thib peb hais yog tias ntau tus neeg tsis quav ntsej txog qhov teeb meem ntawm lub taub hau tinning, kom txuag tau qhov teeb meem, feem ntau ntawm kev siv cov hlau tiav lawm.
Hlau yuav tsis mus rau soldering hlau taub hau tin. Txawm tias tom qab lub taub hau hlau tawm, nws qhov kub thiab txias kuj tseem yuav tshwm sim nrog cov huab cua oxidation, thiab nyob rau hauv lub hwj chim tawm ua ntej nws yog tinned, koj tuaj yeem zam nws raug oxidized.
