Kev xaiv ntawm hom hlau soldering
1. Endothermic soldering hlau. Endothermic soldering hlau qauv yog yooj yim, siab thermal efficiency, hnav thiab saj zawg zog, thaum xaiv thawj. Los ntawm kev sib txuas pas nrig, kov, caij nplooj ntoos hlav clip, hlau core, hlau taub hau (tseem hu ua tooj liab taub hau). Soldering hlau core ntsia rau sab hauv ntawm lub taub hau hlau. Soldering hlau tub ntxhais siv nickel-chromium kuj hlau qhov txhab ntawm lub plooj (porcelain raj) ua los ntawm 20W soldering hlau tsis kam ntawm 2.4kΩ los yog li ntawd, 35W soldering hlau tsis kam ntawm 1.4kΩ los yog li ntawd.
2. Sab nraud kub hom soldering hlau. Cov txheej txheem ntawm kev tsim cov hlau no yog qhov nyuaj, tsis tshua muaj txiaj ntsig, tus nqi siab, feem ntau yog los ntawm lub taub hau hlau, hlau tub ntxhais, plhaub, kov, ntsaws thiab lwm yam. Soldering hlau taub hau ntsia tau rau hauv cov tub ntxhais hlau, nrog zoo thermal conductivity ntawm tooj liab raws li lub substrate ntawm tooj liab alloy khoom ua.
Qhov ntev ntawm lub taub hau hlau tuaj yeem hloov kho (qhov luv ntawm lub taub hau hlau, qhov siab dua qhov kub ntawm lub taub hau hlau). Feem ntau siv hauv kev xyaum yog chisel, taw qhia lub khob hliav qab, puag ncig lub ntsej muag zoo li, puag ncig, taw qhia lub khob hliav qab thiab ib nrab voj voog zawj duab thiab lwm cov duab sib txawv kom haum raws li qhov xav tau ntawm qhov sib txawv vuam nto.
3. Thermostatic soldering hlau. Nyob rau hauv lub taub hau ntawm lub taub hau rau hauv cov hlau nplaum-hom kub maub los tswj lub sij hawm energized, yog cov thermostatic soldering hlau. Nyob rau hauv lub vuam kub yuav tsum tsis txhob siab dhau heev lawm, lub vuam lub sij hawm yuav tsum tsis txhob ntev dhau lawm Cheebtsam, yuav tsum tau siv cov thermostatic soldering hlau, tab sis nws yog kim. Tsis siv neeg thermostatic soldering hlau txawm tias ntau qhov chaw, kev saib xyuas yog qhov nyuaj, tus nqi siab, tab sis nws tuaj yeem lav qhov zoo ntawm qhov taw tes soldering, tshwj xeeb tshaj yog thaum ua cov kev sim hauv Circuit Court thiab kho ntau cov ntawv luam tawm Circuit Court boards, nrog rau cov txiaj ntsig zoo heev. Cov hluav taws xob soldering hlau siv nyob rau hauv cov kab ntau lawm, coj cov kev tswj tsis siv neeg voltage ntawm qhov kub thiab txias, tus nqi yuav qis dua. Qee qhov chaw ntawm lub zog hluav taws xob tsis ruaj khov, cov hlau nplaum feem ntau hlawv tsis dipped hauv cov tin, lossis qhov kub tsis txaus, vuam tsis txav, txhawm rau kom ntseeg tau qhov zoo ntawm brazing, tsuas yog siv cov thermostatic series ntawm cov hlau tsis siv neeg. , los yog configure lub voltage regulator system. Tsuas yog qhov kub thiab txias, series ntawm puck resistor kuj OK.
4. Suction tin soldering hlau. Suction tin soldering hlau yog piston hom tin sucker thiab soldering hlau yaj nyob rau hauv ib qho ntawm cov desoldering cov cuab yeej, nws muaj ib qho yooj yim mus use, saj zawg zog, ntau yam ntawm daim ntawv thov thiab lwm yam ntxwv. Qhov tsis zoo yog tias txhua lub sij hawm tsuas yog ib qho taw qhia rau desoldering.
5. Gas soldering hlau. Yog ib hom roj liquefied, methane thiab lwm yam combustible gas combustion cua sov hlau hlau. Hauv qhov tsis yooj yim ntawm cov khoom siv hluav taws xob lossis tsis tuaj yeem muab hloov pauv tam sim no, koj tuaj yeem xaiv siv. Vim muaj kev pheej hmoo ntawm kev tawg, daim ntawv no tsis tham txog kev yuav cov hlau zoo li no.
