Cov ntsiab lus ntawm cov ntsiab lus tseem ceeb ntawm soldering hlau soldering tshuab
1, kev xaiv ntawm soldering hlau
Lub zog ntawm cov hlau vuam yuav tsum tau txiav txim siab los ntawm qhov loj ntawm qhov vuam taw tes, thaj tsam ntawm qhov vuam taw tes yog qhov loj, qhov vuam taw tes ntawm cov cua sov dissipation ceev kuj ceev, yog li kev xaiv lub zog ntawm cov hlau soldering yuav tsum tau. ua loj. General zog ntawm cov hlau soldering 20W 25W 30W 35W 50W thiab hais txog. Hauv cov txheej txheem tsim khoom, kev xaiv txog 30W fais fab tuag yog qhov tsim nyog dua.
Tom qab siv tau ntev, lub taub hau ntawm cov hlau soldering yuav tsim ib txheej ntawm oxide, ces nws tsis yooj yim rau noj tin, ces koj tuaj yeem siv cov ntaub ntawv tawm ntawm cov oxide txheej, cov hlau soldering yuav muaj zog. , xws li lub taub hau ntawm cov hlau soldering yog kub me ntsis thaum muab tso rau hauv cov rosin, coated nrog solder tuaj yeem txuas ntxiv mus siv cov hlau uas tau muag tshiab yuav tsum nyob rau hauv cov tin thiab tom qab ntawd siv tau.
2, Solder thiab flux
Xaiv qhov qis melting point ntawm cov hlau solder thiab tsis muaj corrosive flux, xws li rosin, yuav tsum tsis txhob siv cov tin thiab corrosive acidic soldering roj, qhov zoo tshaj plaws siv rosin-muaj solder hlau, nws yog heev yooj yim mus use.
3, Txoj kev soldering
Cheebtsam yuav tsum huv si thiab tinned, hluav taws xob Cheebtsam tau txais kev cawmdim nyob rau hauv cov huab cua, vim lub luag hauj lwm ntawm oxidation, cov tivthaiv pins yog txuas mus rau ib tug txheej ntawm oxide zaj duab xis, thaum muaj lwm yam av, welding yuav siv tau los txhuam cov oxidized zaj duab xis, thiab tam sim ntawd coated nrog ib txheej ntawm solder (feem ntau hu ua tin-lined), thiab ces welded. Tom qab cov khoom siv kho mob saum toj no yog qhov yooj yim rau vuam, tsis yooj yim rau tshwm sim virtual vuam tshwm sim.
(1) Kub kub thiab soldering lub sij hawm
Soldering hlau kub yuav tsum siab tshaj qhov kub ntawm lub solder, tab sis tsis siab dhau, thiaj li yuav soldering hlau taub hau hu rosin tsuas yog haus luam yeeb kom zoo. Lub sij hawm soldering yog luv dhau, qhov kub ntawm qhov taw tes soldering tsawg dhau, qhov taw tes soldering tsis tag nrho melted, soldering taw tes ntxhib yooj yim ua rau vuam, thiab vice versa, lub sij hawm soldering yog ntev dhau lawm, lub solder yog yooj yim ntws, thiab yooj yim los ua kom cov khoom overheating puas rau cov khoom.
(2) Tus naj npawb ntawm cov ntsiab lus soldering ntawm lub tin
Vuam taw tes ntawm tus naj npawb ntawm cov solder tsis tuaj yeem tsawg dhau, qhov vuam me me tsis ruaj khov, cov neeg kho tshuab lub zog kuj tsis zoo. Thiab ntau dhau yuav ua rau cov tsos ntawm ntau tus sab hauv tsis txuas nrog. Solder yuav tsum tsuas yog yuav tsum tau soldered ntawm cov khoom siv pins tag nrho cov submerged, cov qauv ntawm lub vaguely pom ib yam.
(3) xyuam xim rau txoj hauj lwm ntawm cov hlau soldering thiab cov ntsiab lus soldering
Beginners nyob rau hauv lub soldering, feem ntau txav lub soldering hlau rov qab mus rau hauv lub vuam los yog nyem nyuaj, txoj kev no yog tsis ncaj ncees lawm. Txoj kev raug yog siv cov hlau soldering lub tin-lined nto hu rau lub vuam taw tes, kom lub tshav kub hloov chaw yog loj, vuam ceev.
4, xyuas tom qab vuam
Tom qab qhov kawg ntawm welding yuav tsum tau kuaj xyuas qhov xau ntawm vuam, soldering thiab luv luv-circuiting ntawm cov khoom uas tshwm sim los ntawm qhov ntws ntawm solder. Virtual vuam yog yooj yim dua mus nrhiav tau, muaj tweezers clamped tivthaiv pins maj mam rub, xws li pom co yuav tsum tam sim ntawd replenished vuam.
