Taw qhia rau cov ntsiab lus tseem ceeb ntawm hluav taws xob soldering hlau vuam tshuab
1. Kev xaiv hluav taws xob soldering hlau
Lub zog ntawm cov hluav taws xob soldering hlau yuav tsum tau txiav txim siab los ntawm qhov loj ntawm qhov sib koom ua ke. Qhov loj ntawm thaj tsam ntawm cov sib koom ua ke, qhov ceev ntawm cov cua sov dissipation ceev ntawm cov solder sib koom, yog li cov xaiv hluav taws xob soldering hlau yuav tsum muaj lub zog ntau dua. Lub zog ntawm lub tshuab hluav taws xob dav dav yog 20W, 25W, 30W, 35W, 50W, thiab lwm yam. Nws yog qhov tsim nyog xaiv lub zog ntawm ib puag ncig 30W thaum lub sijhawm tsim khoom.
Tom qab siv ntev, ib txheej ntawm oxide yog tsim rau ntawm lub taub hau ntawm cov hluav taws xob soldering hlau, ua rau nws nyuaj rau noj tin. Lub sijhawm no, txheej oxide tuaj yeem raug tshem tawm nrog cov ntaub ntawv. Tom qab lub tshuab hluav taws xob tau siv rau, rosin tuaj yeem muab tso rau thaum lub taub hau kub me ntsis, thiab cov tin tuaj yeem siv los txuas ntxiv mus. Cov khoom siv hluav taws xob uas tau muag tshiab yuav tsum tau tinned ua ntej siv.
2. Solder thiab flux
Xaiv qhov qis melting point solder hlau thiab tsis corrosive flux, xws li rosin. Kev lag luam solder thiab corrosive acidic solder roj yuav tsum tsis txhob siv. Nws yog qhov zoo tshaj plaws los siv cov hlau nplaum uas muaj rosin, uas yooj yim heev rau siv.
3. Vuam txoj kev
Cov khoom yuav tsum tau ntxuav thiab tinned, thiab cov khoom siv hluav taws xob yuav tsum tau khaws cia hauv huab cua. Vim yog oxidation, ib txheej ntawm oxide zaj duab xis txuas nrog cov pins ntawm cov khoom, nrog rau lwm cov av. Ua ntej welding, ib rab riam me tuaj yeem siv los txhuam cov oxide zaj duab xis thiab tam sim ntawd siv ib txheej ntawm cov hlau nplaum (feem ntau hu ua tin hauv ob sab phlu) ua ntej vuam. Tom qab cov kev kho mob saum toj no, cov khoom yog ib qho yooj yim rau solder khov kho thiab tsis nquag mus dag soldering.
(1) Vuam kub thiab vuam lub sij hawm
Thaum welding, qhov kub ntawm cov hluav taws xob soldering hlau yuav tsum siab tshaj qhov kub ntawm lub soldering tin, tab sis nws yuav tsum tsis txhob siab dhau heev lawm, nyiam dua thaum lub soldering hlau taub los rau hauv kev sib cuag nrog rosin thiab tsuas yog haus luam yeeb. Yog tias lub sijhawm vuam luv dhau, qhov kub ntawm qhov sib koom ua ke yog qis dhau, lub melting ntawm cov sib koom ua ke tsis txaus, thiab cov khoom sib txuas yog ntxhib, uas tuaj yeem ua rau tsis muaj tseeb. Hloov pauv, yog tias lub sijhawm vuam ntev dhau lawm, cov khoom siv tau yooj yim ntws thiab ua rau overheating thiab puas rau cov khoom.
(2) Tus naj npawb ntawm cov tin siv rau cov ntsiab lus vuam
Tus nqi ntawm cov vuam ntawm qhov vuam yuav tsum tsis txhob me me, vim nws me dhau thiab qhov vuam tsis ruaj khov, thiab lub zog siv tshuab kuj tsis zoo. Thiab ntau dhau tuaj yeem yooj yim ua rau ntau qhov tsos thiab kev cuam tshuam sab hauv. Solder yuav tsum cia li raus tag nrho cov tivthaiv pins ntawm qhov taw tes soldering, nrog cov qauv pom.
(3) Ua tib zoo saib xyuas qhov chaw ntawm cov hlau thiab cov ntsiab lus vuam
Thaum pib vuam, lawv feem ntau txav cov hluav taws xob soldering hlau rov qab los yog quab yuam kom nyem nws ntawm qhov chaw vuam, uas yog txoj kev tsis ncaj ncees lawm. Txoj kev raug yog siv cov tin coated nto ntawm ib qho hluav taws xob soldering hlau hu rau lub vuam taw tes, uas muaj ib tug loj tshav kub hloov chaw thiab ceev vuam ceev.
4. Kev tshuaj xyuas tom qab vuam
Tom qab lub vuam tiav lawm, nws yuav tsum tau kuaj xyuas cov dej xau, qhov tsis zoo ntawm cov khoom siv, thiab cov khoom siv luv luv ntawm cov khoom los ntawm cov khoom siv. False soldering yog qhov nyuaj rau kev kuaj xyuas, yog li cov tweezers tuaj yeem siv los clamp cov pins tivthaiv thiab maj mam rub lawv. Yog tias pom kev co, kho vuam yuav tsum tau nqa tam sim ntawd.
