4 qhov tseem ceeb soldering txuj ci rau hluav taws xob soldering hlau
Thaum lub sij hawm tu fabrication txheej txheem, vuam ua hauj lwm yog qhov tseem ceeb. Nws tsis tsuas yog yuav tsum tau kho cov khoom ntawm lub rooj tsavxwm, tab sis kuj xav kom cov pob qij txha yuav tsum ruaj 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 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 taw tes soldering. Lub cheeb tsam ntawm qhov taw tes soldering yog loj, thiab qhov kub dissipation ceev ntawm lub soldering point kuj yog ceev, yog li lub zog ntawm cov hlau soldering yuav tsum loj dua. Feem ntau, lub zog ntawm cov hluav taws xob hluav taws xob yog 20W 25W 30W 35W 50W thiab lwm yam. Nws yog qhov tsim nyog xaiv lub zog ntawm 30W.
Tom qab cov hluav taws xob soldering hlau tau siv rau lub sijhawm ntev, ib txheej ntawm oxide yuav raug tsim rau ntawm qhov kawg ntawm cov hlau soldering. Lub sijhawm no, nws tsis yooj yim rau noj tin. Lub sijhawm no, koj tuaj yeem siv cov ntaub ntawv los ua cov txheej txheem oxide. Tom qab cov hlau soldering yog siv rau, ntxig cov rosin thaum lub ntsis ntawm cov hlau soldering kub me ntsis. , Koj tuaj yeem siv nws txuas ntxiv tom qab siv cov khoom siv, thiab cov khoom siv hluav taws xob tshiab yuav tsum tau tinned ua ntej nws tuaj yeem siv tau.
2. Solder thiab Flux
Xaiv cov hlau nplaum uas muaj cov ntsiab lus melting tsawg thiab tsis muaj corrosive flux, xws li rosin. Nws tsis tsim nyog siv cov khoom lag luam thiab corrosive acid solder roj. Nws yog qhov zoo dua los siv cov hlau nplaum uas muaj rosin, uas yooj yim heev rau siv.
3. Vuam txoj kev
Cheebtsam yuav tsum tau ntxuav thiab tinned. Cov khoom siv hluav taws xob yog nyob rau hauv cia. Vim cov nyhuv ntawm huab cua oxidation, ib txheej ntawm oxide zaj duab xis yog txuas rau cov khoom siv pins, thiab muaj lwm yam av. Ua ntej vuam, cov oxide zaj duab xis tuaj yeem raug khawb tawm nrog rab riam, thiab ib txheej yuav tsum tau thov tam sim ntawd. Solder (feem ntau hu ua enamel), thiab ces solder. Tom qab kev kho mob saum toj no, cov khoom siv tau yooj yim rau vuam khov kho, thiab qhov tshwm sim ntawm kev vuam virtual tsis yooj yim tshwm sim. soldering kub thiab soldering lub sij hawm
Thaum soldering, qhov kub ntawm cov hluav taws xob soldering hlau yuav tsum siab tshaj qhov kub ntawm lub solder, tab sis nws yuav tsum tsis txhob siab dhau. Nws yog qhov zoo dua tias cov hlau nplaum txuas nrog cov rosin ua ntej haus luam yeeb. Yog hais tias lub sij hawm soldering yog luv luv, qhov kub ntawm cov pob qij txha yog tsawg heev, cov pob qij txha solder tsis tag melted, thiab cov pob qij txha solder yog ntxhib thiab yooj yim los ua cuav soldering. Ntawm qhov tsis sib xws, lub sij hawm soldering yog ntev dhau lawm, lub solder yog yooj yim ntws, thiab nws yog ib qho yooj yim uas yuav ua rau lub Cheebtsam overheat thiab puas lub Cheebtsam.
Tus nqi ntawm cov tin ntawm lub solder sib koom
Tus nqi ntawm solder ntawm qhov taw tes soldering yuav tsum tsis txhob me me, yog tias nws tsawg dhau, qhov vuam yuav tsis muaj zog, thiab cov neeg kho tshuab lub zog yuav tsis zoo. Thiab ntau dhau yog ib qho yooj yim ua rau ntau qhov tsos tab sis tsis txuas nrog sab hauv. Lub solder yuav tsum cia li submerge tag nrho cov tivthaiv ua nyob rau hauv lub soldering point, thiab cov qauv yuav tsum faintly pom.
Ua tib zoo saib rau txoj hauj lwm ntawm cov hlau soldering thiab qhov taw tes soldering
Thaum cov neeg pib pib siv, lawv feem ntau txav cov hlau rov qab los yog nyem nyuaj ntawm qhov chaw soldering. Txoj kev no tsis yog lawm. Txoj kev raug yog siv cov tin-coated nto ntawm cov hluav taws xob soldering hlau los kov lub soldering point, kom lub tshav kub hloov chaw yog loj thiab vuam ceev.
4. Kev tshuaj xyuas tom qab vuam
Tom qab soldering, nws yog ib qhov tsim nyog los xyuas seb puas muaj cov soldering uas ploj lawm, virtual soldering, thiab cov khoom luv luv Circuit Court tshwm sim los ntawm solder flow. Vuam tsis yooj yim nrhiav tau, koj tuaj yeem siv cov tweezers los tuav cov pins tivthaiv thiab rub nws maj mam, yog tias koj pom tshee, koj yuav tsum kho lub soldering tam sim ntawd.
