Yuav ua li cas junior electricians siv ib tug soldering hlau? Cov lus qhia rau kev siv cov hlau soldering
1. Xaiv qhov tsim nyog zoo solder, thiab qis melting point solder hlau rau vuam cov khoom siv hluav taws xob yuav tsum tau siv.
2. Rau qhov tsim nyog tus nqi ntawm flux, siv 25% rosin yaj hauv 75% cawv (qhov hnyav piv) ua flux. Tus nqi tsim nyog ntawm flux yog qhov tseem ceeb, tab sis tsis txhob xav tias ntau dua yog qhov zoo dua. Cov rosin ntau dhau tsis tsuas yog ua rau cov khoom siv tu kom zoo nyob ib puag ncig cov pob qij txha tom qab vuam.
3. Lub tshuab hluav taws xob yuav tsum tau tinned ua ntej siv. Txoj kev tshwj xeeb yog: tshav kub ntawm hluav taws xob soldering hlau. Thaum lub solder tsuas yog melted, thov flux, thiab ces thov lub solder tusyees ntawm lub soldering hlau ntsis kom lub soldering hlau taub yuav sib npaug zos coated. Ib txheej ntawm tin.
4. Rau txoj kev vuam, txhuam cov ntaub qhwv thiab cov khoom sib txuas kom huv si nrog cov ntawv xuab zeb zoo thiab siv flux. Dip tus nqi tsim nyog ntawm solder nrog lub ntsis ntawm cov hlau soldering thiab kov nws mus rau qhov sib koom ua ke. Tom qab tag nrho cov solder nyob rau hauv lub solder sib koom ua ke melts thiab immerses cov hlau lead ntawm cov khoom, maj mam nqa lub taub hau ntawm lub soldering hlau nyob rau hauv cov hlau lead ntawm cov khoom thiab deb ntawm lub solder sib koom.
5. Lub sijhawm vuam yuav tsum tsis txhob ntev dhau, txwv tsis pub nws yog qhov yooj yim rau hlawv cov khoom. Yog tias tsim nyog, siv cov tweezers txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau kub.
6. Cov pob qij txha yuav tsum nyob rau hauv cov duab ntawm lub sinusoidal yoj ncov, thiab saum npoo yuav tsum ci thiab du yam tsis muaj tin pos.
7. Tus nqi ntawm soldering yuav tsum tsim nyog. Ntau dhau soldering tsis tsuas yog siv cov tin kim kim tsis tsim nyog, tab sis kuj nce lub sij hawm soldering thiab raws li txo cov kev ua hauj lwm ceev. Qhov loj tshaj yog tias nyob rau hauv high-density circuits, ntau tshaj tin tuaj yeem yooj yim ua rau tsis pom kev luv luv.
8. Tom qab lub soldering tiav lawm, siv cawv los ntxuav cov flux seem ntawm lub rooj tsav xwm Circuit Court kom tsis txhob muaj cov pa roj carbonized los ntawm kev cuam tshuam rau kev ua haujlwm ntawm lub voj voog.
9. Cov kev sib xyaw ua ke yuav tsum tau soldered kawg, thiab cov hlau soldering yuav tsum muaj kev ntseeg siab hauv av, los yog cov khoom siv hluav taws xob yuav tsum tau siv rau kev ua haujlwm tom qab fais fab tuag. Los yog siv lub qhov (socket) tshwj xeeb rau kev sib xyaw ua ke, thiab tom qab ntawd ntsaws rau hauv qhov sib xyaw ua ke tom qab soldering lub qhov (socket).
10. Lub soldering hlau yuav tsum tau muab tso rau ntawm lub soldering hlau sawv ntsug.
