Cov lus qhia rau kev siv cov hlau soldering nrog qhov kub thiab txias
1. Kev npaj ntawm qhov ntsuas kub tsis tu ncua ua ntej siv:
Ua ntej yuav siv ib qho tshiab-kub soldering hlau, lub taub hau hlau yuav tsum tau plated nrog ib txheej ntawm solder ua ntej nws tuaj yeem siv tau ib txwm. Thaum qhov kub thiab txias ntawm cov hlau siv rau ib lub sij hawm, cov oxide txheej yuav raug tsim rau thiab nyob ib ncig ntawm cov hniav ntawm cov hlau taub hau, ua rau "tin noj". "Yog tias nws yog qhov tshwm sim nyuaj, koj tuaj yeem ua cov txheej txheem oxide thiab rov plat nws nrog solder.
2. Yuav ua li cas tuav lub qhov kub thiab txias soldering hlau:
a. Rov qab tuav: tuav tus tuav ntawm qhov ntsuas kub tsis tu ncua ntawm koj txhais tes nrog koj tsib ntiv tes. Txoj kev no yog tsim rau high-power tas li kub hluav taws xob soldering hlau rau weld qhov chaw uas dissipate loj npaum li cas ntawm tshav kub.
b. Txoj kev tuav rau pem hauv ntej: Tuav qhov ntsuas kub tsis tu ncua ntawm cov hlau kov nrog plaub ntiv tes tshwj tsis yog tus ntiv tes xoo, thiab nias tus ntiv tes xoo raws li kev taw qhia ntawm cov hlau soldering. Cov hlau soldering siv nyob rau hauv txoj kev no kuj tseem loj, thiab feem ntau ntawm lawv muaj nkhaus soldering hlau taub hau.
c. Cwj mem tuav txoj kev: Tuav lub ntsuas kub tsis tu ncua zoo li tus cwj mem. Nws yog tsim rau cov uas tsis muaj zog soldering hlau thiab vuam me me qhov chaw yuav tsum tau welded.
3. Vuam cov kauj ruam:
Thaum lub sij hawm vuam txheej txheem, cov cuab yeej yuav tsum tau muab tso rau kom huv si thiab qhov kub thiab txias ntawm soldering hlau yuav tsum tau tuav tsis tu ncua thiab ua raws. Rau kev sib cuag welding, nws yog qhov zoo tshaj plaws los siv rosin-laced tubular solder hlau. Tuav tus tuav ntawm qhov ntsuas kub tsis tu ncua ntawm ib txhais tes thiab cov hlau soldering nyob rau lwm qhov.
1. Ib txoj hauv kev yog kom ceev nrooj hu rau cov cua sov thiab tinned soldering hlau taub nrog cov hlau cored, thiab tom qab ntawd hu rau qhov chaw sib koom ua ke, siv cov molten solder los pab cov cua sov ua ntej los ntawm cov hlau soldering mus rau qhov chaw ua haujlwm, thiab tom qab ntawd tshem tawm cov khoom siv. tin cev. Tshem tawm lub taub hau ntawm cov hlau soldering.
2. Ib txoj hauv kev yog kov lub taub hau ntawm lub taub hau rau tus pin / ncoo thiab tso 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, qhov tshwm sim feem ntau yog siv qhov ntsuas kub tsis tsim nyog, siab dhau, lub sijhawm khaws cia ntev, lossis kev sib xyaw ntawm peb, uas ua rau muaj kev puas tsuaj rau PCB lossis cov khoom siv.
4. Kev ceev faj rau kev siv hluav taws xob kub tsis tu ncua 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. Muab cov lus qhia ntawm cov hlau nplaum sib txawv ntawm qhov sib txawv ntawm cov rosin thaiv yuav tsim cov phenomena sib txawv. Feem ntau hais lus, qhov kub thiab txias thaum lub rosin melts sai thiab tsis haus 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 cov taw tes rau lub sij hawm thaum lub solder melts thiab ntws hla lub soldering point, 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, cov flux ntawm lub vuam taw tes yuav tag nrho evaporate thiab cov nyhuv vuam 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 tuaj yeem ua rau cov vuam tsis zoo.
3. Siv tus nqi tsim nyog ntawm solder thiab flux. Feem ntau, siv ntau dhau los yog tsawg dhau los thiab cov flux ntawm vuam cov ntsiab lus yuav muaj kev cuam tshuam zoo rau qhov vuam zoo.
4. Tiv thaiv lub vuam ntawm qhov vuam ntawm qhov ntws los ntawm qhov tsis sib xws. 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, yuav tsum muaj tsawg dua solder thaum pib. Tom qab lub vuam taw tes ncav cuag qhov vuam kub thiab cov vuam ntws mus rau hauv qhov sib txawv ntawm qhov vuam taw tes, rov ua kom tiav cov vuam kom tiav qhov vuam sai.
5. Tsis txhob kov qhov taw tes soldering thaum lub sij hawm vuam txheej txheem nrog rau qhov kub thiab txias hluav taws xob soldering hlau. Thaum lub solder ntawm qhov taw tes soldering tsis tau ua tiav, cov khoom siv soldering thiab cov xov hlau ntawm qhov taw tes soldering yuav tsum tsis txhob txav mus, txwv tsis pub cov taw tes soldering yuav deformed thiab virtual soldering yuav tshwm sim.
6. Thaum vuam nrog qhov kub thiab txias tsis tu ncua, koj yuav tsum tsis txhob hlawv cov khoom nyob ib puag ncig thiab cov xov hlau. Thaum vuam, ceev faj kom tsis txhob cia cov hlau nplaum hlawv cov yas rwb thaiv tsev ntawm cov xov hlau nyob ib puag ncig thiab qhov chaw ntawm cov khoom, tshwj xeeb tshaj yog rau cov khoom uas muaj cov qauv sib txuas thiab cov duab nyuaj. .
7. Tom qab vuam tiav lawm, ntxuav tom qab vuam hauv lub sijhawm. Tom qab vuam tiav lawm, cov hlau txiav xaus thiab tin slag poob thaum lub vuam yuav tsum tau muab tshem tawm hauv lub sijhawm kom tsis txhob poob rau hauv cov khoom thiab ua rau muaj kev phom sij zais.
