Cov lus qhia rau kev siv ntawm qhov kub thiab txias soldering hlau
1. Kev npaj ntawm qhov ntsuas kub tsis tu ncua ua ntej siv:
Ua ntej yuav siv ib tug tshiab-kub soldering hlau, lub soldering hlau taub yuav tsum tau plated nrog ib tug txheej ntawm solder ua ntej nws yuav siv tau ib txwm. Thaum qhov kub thiab txias ntawm cov hlau siv rau ib lub sij hawm, ib txheej oxide 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 ntaub ntawv tawm ntawm oxide txheej thiab rov plat nws nrog solder.
2. Yuav ua li cas tuav lub qhov kub thiab txias soldering hlau:
ib. 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 kub thiab txias ntawm cov hlau kov nrog plaub ntiv tes tshwj tsis yog tus ntiv tes xoo, thiab nias tus ntiv tes xoo raws li cov 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 pib 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.
