Soldering tswv yim rau hluav taws xob soldering hlau
Hauv kev kho thiab tsim khoom, kev ua haujlwm vuam yog qhov tseem ceeb. Nws tsis tsuas yog yuav tsum tau kho cov khoom sib txuas ntawm lub rooj tsavxwm, tab sis kuj yuav tsum tau cov pob qij txha kom ruaj khov thiab du. Yog li ntawd, qhov zoo ntawm vuam tshuab ncaj qha cuam tshuam rau kev ua tiav ntawm kev tsim hluav taws xob. Yog li ntawd, vuam tshuab yog ib qho kev txawj ntse uas txhua tus neeg siv khoom siv hluav taws xob yuav tsum paub. Tam sim no peb yuav qhia cov ntsiab lus tseem ceeb ntawm vuam:
1. Xaiv cov hlau soldering
Lub zog ntawm cov hlau soldering yuav tsum tau txiav txim siab los ntawm qhov loj ntawm qhov sib koom ua ke. Qhov loj dua qhov chaw sib koom ua ke, qhov nrawm dua qhov cua sov ntawm qhov sib koom ua ke. Yog li ntawd, lub zog ntawm cov hlau soldering yuav tsum loj dua. Feem ntau, lub zog ntawm cov hlau nplaum yog 20W, 25W, 30W, 35W, 50W thiab lwm yam. Nws yog qhov tsim nyog xaiv lub zog ntawm 30W.
Tom qab hluav taws xob soldering hlau siv tau ntev, ib txheej ntawm oxide yuav raug tsim rau ntawm lub taub hau ntawm cov hlau soldering. Lub sijhawm no, nws yuav tsis yooj yim rau noj tin. Lub sijhawm no, koj tuaj yeem siv cov ntaub ntawv tshem tawm cov oxide txheej. Tom qab cov hlau soldering yog powered on, ntxig rosin thaum lub taub hau ntawm cov hlau soldering kub me ntsis. , thov solder thiab koj tuaj yeem siv txuas ntxiv mus. Cov hlau uas tau yuav tshiab yuav tsum tau tinned ua ntej nws tuaj yeem siv tau.
2. Solder thiab flux
Xaiv qhov qis melting point solder hlau thiab non-corrosive flux, xws li rosin. Nws tsis tsim nyog siv cov khoom siv thiab corrosive acidic soldering roj. Nws yog qhov zoo tshaj plaws los siv cov hlau nplaum uas muaj rosin, uas yooj yim heev rau siv.
3. Vuam txoj kev
Cheebtsam yuav tsum huv si thiab tin-plated. Thaum cov khoom siv hluav taws xob tau khaws cia, vim yog oxidation ntawm huab cua, yuav muaj oxide zaj duab xis ntawm cov khoom siv pins, nrog rau lwm yam av. Ua ntej vuam, koj tuaj yeem siv rab riam los txhuam cov oxide zaj duab xis thiab tam sim ntawd thov ib txheej ntawm nws. Solder (feem ntau hu ua tin enamel), thiab ces solder. Tom qab kev kho mob saum toj no, cov khoom siv tau yooj yim soldered ruaj khov thiab qhov tshwm sim ntawm kev tsis ncaj ncees soldering tsis tshua muaj tshwm sim. Vuam kub thiab vuam lub sij hawm
Thaum vuam, qhov kub ntawm cov hluav taws xob soldering hlau yuav tsum siab tshaj qhov kub ntawm lub solder, tab sis tsis siab dhau. Nws yog qhov zoo dua rau cov hlau taub hau tsuas yog haus luam yeeb thaum nws kov cov rosin. Yog tias lub sijhawm vuam luv dhau, qhov kub ntawm cov pob qij txha yuav qis dhau, cov pob qij txha yuav tsis yaj txaus, thiab cov pob qij txha yuav ntxhib, uas tuaj yeem ua rau tsis muaj tseeb. Ntawm qhov tsis sib xws, yog tias lub sijhawm vuam ntev dhau lawm, lub vuam yuav ntws tau yooj yim, thiab cov khoom yuav yooj yim overheated thiab puas.
Tus naj npawb ntawm tinned solder pob qij txha
Tus nqi ntawm solder ntawm qhov taw tes soldering tsis tuaj yeem tsawg dhau. Yog tias nws me dhau lawm, qhov vuam yuav tsis muaj zog thiab cov neeg kho tshuab lub zog yuav tsis zoo. Thiab ntau dhau tuaj yeem yooj yim ua rau ntau yam ntawm sab nraud tab sis tsis txuas rau sab hauv. Lub solder yuav tsum cia li raus tag nrho cov tivthaiv pins ntawm lub soldering point, thiab cov qauv yuav tsum tau vaguely pom.
Ua tib zoo saib rau txoj haujlwm ntawm cov hlau soldering thiab cov pob qij txha
Thaum welding, cov pib feem ntau txav cov hlau rov qab thiab tawm ntawm qhov chaw vuam los yog nyem nws nyuaj. Txoj kev no tsis yog lawm. Txoj kev raug yog siv cov tin-lined nto ntawm cov hlau soldering hu rau qhov taw tes soldering, kom lub tshav kub hloov chaw yog qhov loj thiab qhov ceev ntawm soldering yog ceev.
4. Kev tshuaj xyuas tom qab vuam
Tom qab vuam, nws yog ib qho tsim nyog yuav tsum tau xyuas seb puas muaj cov solders uas ploj lawm, tsis muaj zog solders, thiab cov khoom luv luv Circuit Court tshwm sim los ntawm solder flow. Vuam yog qhov nyuaj rau kev kuaj xyuas. Koj tuaj yeem siv cov tweezers los tuav cov pins tivthaiv thiab maj mam rub lawv. Yog tias pom kev co, kho lub soldering tam sim ntawd.
