Soldering Hlau Soldering Basics
Soldering hlau yog ib qho cuab yeej tseem ceeb rau kev saib xyuas, nws cov cuab yeej siv vuam yog lub hauv paus ntawm kev ua haujlwm tu, cov kws kho mob zoo, tsuas yog ua ntej ntawm tag nrho cov kev txawj ntse ntawm vuam cov khoom, tsuas yog rau kev saib xyuas ntawm lub hauv paus zoo, nws muaj peev xwm ua tau ib qho kev txawj ntse ntawm cov khoom siv vuam. txoj haujlwm zoo ntawm kev saib xyuas.
(1) sab nraud kub soldering hlau
Soldering hlau taub hau ntsia tau rau hauv cov tub ntxhais hauv cov hlau soldering yog hu ua lwm yam cua sov hom soldering hlau. Hauv cov khoom siv hluav taws xob hauv tsev kho vaj tse, kev siv 30 ~ 35 W tuaj yeem ua tau raws li qhov xav tau.
(2) Internal tshav kub hom soldering hlau
Soldering hlau core ntsia tau rau hauv lub taub hau hlau nyob rau hauv lub soldering hlau, lub npe hu ua endothermic soldering hlau, endothermic soldering hlau kub ceev, siab kub siv tus nqi. Nyob rau hauv PC board daim npav chav kawm nti-theem tu, kev xaiv ntawm 35 ~ 40 W tuaj yeem ua tau raws li qhov xav tau.
(3) Thermostatic soldering hlau
Nyob rau hauv lub taub hau soldering hlau, nruab nrog ib tug hlau nplaum hom ntawm kub xws li, tswj txiav lub hwj chim lub sij hawm thiab paub qhov kev tswj kub ntawm soldering hlau, hu ua thermostatic soldering hlau.
Nyob rau hauv lub welding integrated circuits, transistors Cheebtsam, qhov kub thiab txias tsis tuaj yeem siab dhau, lub sijhawm vuam tsis tuaj yeem ntev dhau, txwv tsis pub nws yuav yog vim qhov kub siab dhau los ua rau muaj kev puas tsuaj rau cov khoom, thiab yog li ntawd qhov kub thiab txias. soldering hlau muab rau txwv. Qhov ntsuas kub tsis tu ncua soldering hlau tshwj xeeb yog tsim los rau qhov kev xav tau no.
(4) Suction tin hom soldering hlau
Suction soldering hlau yog piston hom solder absorber thiab soldering hlau rau hauv ib qho ntawm cov cuab yeej desoldering.
1, Solder khoom
Cov khoom siv solder yog ua los ntawm tin-lead alloy thiab ib qho nyiaj ntawm cov khoom siv hluav taws xob tau teeb tsa hauv ib qho kev faib ua feem, feem ntau 63% ntawm cov tin, txhuas suav rau 37%, qhov kub liquefaction ntawm lub solder hauv 400 degree (750 ″ F) hauv qab no .
Cov khoom siv feem ntau yog tin bars, tin ingots, tin hlau, tin hmoov, prefabricated ingots, tin pob thiab kab, tin muab tshuaj txhuam thiab ob peb lwm hom solder, uas cov hlau solder yog tsuas yog siv rau ntau yam hluav taws xob thiab hluav taws xob industries, luam ntawv Circuit Court boards, microelectronics technology, xws li phau ntawv welding txheej txheem, raws li qhia nyob rau hauv daim duab rau lub solder hlau.
2, flux
Flux feem ntau yog siv los tshem tawm cov oxidized txheej ntawm cov khoom siv soldered, kom cov khoom siv thiab cov khoom siv tau zoo ua ke.
solder yuav tsum muaj ib tug kiag li oxidation-dawb nto yuav tsum tau ua ke nrog lub solder, thiab nyob rau hauv lub vuam, hlau ib zaug raug rau saum huab cua yuav tsim ib tug oxide txheej, no oxide txheej tsis tuaj yeem ntxuav nrog cov kuab tshuaj ib txwm, lub sij hawm no koj yuav tsum cia siab rau. cov flux thiab oxidized txheej ntawm cov tshuaj tiv thaiv, thiaj li yuav raug tshem tawm kom huv si.
Feem ntau cov flux feem ntau inorganic flux, organic acid flux, rosin flux thiab li ntawm ntau hom flux, suav nrog rosin flux hauv phau ntawv vuam yog siv ntau dua.
