Muaj peev xwm nrog qhov ntsuas kub tsis tu ncua
Ua ntej, kev kho mob ntawm qhov ntsuas kub tsis tu ncua hluav taws xob soldering hlau ua ntej siv:
Tus tshiab qhov kub thiab txias hluav taws xob soldering hlau tuaj yeem siv tau ib txwm siv tom qab txheej txheej ntawm cov hlau nplaum nrog cov txheej txheem ua ntej siv. Tom qab qhov kub thiab txias hluav taws xob soldering hlau yog siv rau ib lub sij hawm, ib txheej ntawm oxide txheej yuav raug tsim nyob rau ntawm cov hniav nto ntawm lub soldering hlau taub thiab nyob ib ncig ntawm nws, uas yuav ua rau "tin noj" "Qhov tshwm sim nyuaj, lub sij hawm no. oxide txheej tuaj yeem raug foob thiab rov plated nrog solder.
Thib ob, txoj kev tuav ntawm qhov kub thiab txias hluav taws xob soldering hlau:
ib. Txoj kev tuav rov qab: siv tsib ntiv tes los tuav tus tuav ntawm qhov kub thiab txias ntawm hluav taws xob soldering hlau hauv xib teg. Txoj kev no yog tsim rau high-power tas li-kub hluav taws xob soldering hlau, vuam qhov chaw nrog loj tshav kub dissipation.
b. Txoj kev tuav rau pem hauv ntej: Tuav tus kov ntawm qhov kub thiab txias ntawm hluav taws xob soldering hlau nrog plaub ntiv tes tshwj tsis yog tus ntiv tes xoo, thiab nias tus ntiv tes xoo kom nruj raws li cov kev taw qhia ntawm cov hluav taws xob soldering hlau. Cov hluav taws xob soldering hlau siv nyob rau hauv txoj kev no kuj tseem loj heev, thiab feem ntau ntawm lawv yog cov lus qhia nkhaus soldering hlau.
c. Cwj mem tuav txoj kev: tuav lub ntsuas kub tsis tu ncua hluav taws xob soldering hlau zoo li tuav tus cwj mem, haum rau lub zog me me hluav taws xob soldering hlau, vuam me me welded qhov chaw
3. Vuam cov kauj ruam:
Thaum lub sij hawm txheej txheem soldering, cov cuab yeej yuav tsum tau muab tso rau kom huv si, thiab qhov kub thiab txias ntawm hluav taws xob soldering hlau yuav tsum tau tuav ruaj khov thiab ua kom zoo. Rau kev sib koom tes dav dav, nws yog qhov zoo tshaj plaws los siv tubular solder hlau nrog rosin. Tuav tus kov ntawm qhov kub thiab txias tsis tu ncua hluav taws xob soldering hlau nyob rau hauv ib txhais tes thiab lub solder hlau nyob rau hauv lwm yam.
1. Ib txoj hauv kev yog kom ceev cov rhuab thiab tinned soldering hlau taub hau rau hauv kev sib cuag nrog cov cored hlau (cored hlau), ces kov lub solder sib koom cheeb tsam, siv lub molten solder los pab thawj tshav kub conduction los ntawm soldering hlau mus rau lub workpiece. , thiab tom qab ntawd muab cov tin hlau Txav mus rau qhov kawg ntawm cov hlau soldering kom deb ntawm qhov chaw soldering.
2. Ib txoj hauv kev yog kov lub taub hau ntawm lub taub hau rau tus pin / lub ncoo, muab cov tin hlau ntawm lub taub hau thiab tus pin los ua tus choj thermal; tom qab ntawd ceev nrooj txav cov tin hlau mus rau sab nraud ntawm thaj chaw soldering point.
Txawm li cas los xij, hauv cov txheej txheem tsim khoom, feem ntau muaj kev puas tsuaj rau PCB lossis cov khoom siv los ntawm kev siv qhov kub thiab txias, siab ntau dhau, lub sijhawm nyob ntev, lossis kev sib xyaw ntawm peb.
4. Kev ceev faj rau vuam nrog qhov kub thiab txias hluav taws xob soldering hlau:
1. Qhov ntsuas kub ntawm lub taub hau ntawm qhov ntsuas kub tsis tu ncua hluav taws xob soldering hlau yuav tsum tsim nyog. Cov lus qhia kub sib txawv ntawm cov hlau nplaum yuav tsim cov xwm txheej sib txawv thaum muab tso rau ntawm rosin thaiv. Feem ntau hais lus, qhov kub thiab txias thaum lub rosin melts sai thiab tsis emit pa luam yeeb yog tsim nyog.
2. Lub sijhawm vuam ntawm qhov ntsuas kub tsis tu ncua hluav taws xob soldering hlau yuav tsum tsim nyog. Los ntawm cua sov lub ntsiab lus rau melting lub solder thiab sau lub soldering point, feem ntau nws yuav tsum tau ua kom tiav nyob rau hauv ob peb vib nas this. Yog hais tias lub sij hawm vuam ntev dhau lawm, qhov flux ntawm qhov taw tes soldering yuav tag nrho volatilize, thiab cov nyhuv fluxing yuav ploj. Yog tias lub sijhawm vuam luv dhau lawm, qhov kub ntawm qhov vuam taw tes yuav tsis ncav cuag qhov kub ntawm qhov vuam, thiab lub vuam yuav tsis tau yaj tag, uas yuav yooj yim ua rau vuam cuav.
3. Tus nqi ntawm solder thiab flux yuav tsum tau siv kom tsim nyog. Feem ntau, ntau dhau los yog me me ntawm cov solder thiab flux ntawm qhov taw tes soldering yuav muaj kev cuam tshuam zoo rau qhov vuam zoo.
4. Tiv thaiv kom tsis txhob muaj qhov vuam ntawm qhov chaw vuam los ntawm kev ntws mus los ntawm kev ywj pheej. Qhov zoo tshaj plaws welding yuav tsum yog tias lub solder tsuas yog welded qhov twg nws yuav tsum tau welded. Hauv kev ua haujlwm vuam, lub vuam yuav tsum tsawg dua thaum pib. Tom qab qhov taw tes soldering nce mus txog qhov kub thiab txias thiab cov khoom siv ntws mus rau hauv qhov sib txawv ntawm qhov taw tes soldering, lub solder yog ntxiv kom tiav cov soldering sai sai.
5. Tsis txhob kov qhov taw tes soldering thaum lub sij hawm vuam txheej txheem ntawm qhov kub thiab txias hluav taws xob soldering hlau. Thaum lub solder ntawm qhov taw tes soldering tsis tau ua tiav, cov cuab yeej soldered thiab xaim ntawm qhov taw tes soldering yuav tsum tsis txhob txav mus, txwv tsis pub cov taw tes soldering yuav raug deformed thiab yuav tshwm sim virtual soldering tshwm sim.
6. Thaum vuam nrog qhov kub thiab txias tsis tu ncua hluav taws xob soldering hlau, cov khoom nyob ib puag ncig thiab cov xov hlau yuav tsum tsis txhob scalded. Thaum soldering, yuav tsum ceev faj tsis txhob cia cov hluav taws xob soldering hlau hlawv cov yas rwb thaiv tsev txheej ntawm cov nyob ib puag ncig ntawm cov xov hlau thiab qhov chaw ntawm lub Cheebtsam, tshwj xeeb tshaj yog rau cov khoom uas muaj ib tug kuj compact welding qauv thiab ib tug kuj nyuaj. .
7. Tom qab vuam tiav lawm, kev ua haujlwm tu tom qab vuam yuav tsum ua tiav raws sijhawm. Tom qab lub vuam tiav lawm, txiav tawm cov hlau xaus thiab cov tin slag poob thaum lub vuam yuav tsum tau muab tshem tawm raws sij hawm kom tsis txhob muaj kev puas tsuaj los ntawm kev poob rau hauv cov khoom.
