Kev ua haujlwm ntawm hluav taws xob soldering hlau
2.1 Pre-welding kev kho mob:
Ua ntej soldering, cov khoom siv pins lossis cov khoom siv hluav taws xob ntawm lub rooj tsav xwm yuav tsum tau soldered. Feem ntau, muaj peb kauj ruam: "scraping", "plating" thiab "testing".
1. "Scraping" yog los ntxuav qhov vuam ua ntej vuam. Cov cuab yeej siv feem ntau yog cov riam thiab cov ntawv xuab zeb zoo los ntxuav cov pins ntawm kev sib xyaw ua ke thiab cov ntawv luam tawm, tab sis cov pins yuav tsum tau ua kom huv si. Rau nws tus kheej-ua luam ntawv Circuit Court boards, qhov saum npoo ntawm cov ntawv ci tooj liab yuav tsum tau polished nrog cov ntawv xuab zeb zoo ua ntej, thiab cov av ntawm cov ntawv luam tawm Circuit Board yuav tsum tau ntxuav, thiab tom qab ntawd coated nrog rosin cawv tov, flux lossis "HP{{2} }" ua ntej siv. Rau cov kub-plated nyiaj alloy hlau lead-tawm xov hlau, cov txheej tsis tuaj yeem raug khawb tawm, thiab cov av tuaj yeem raug wiped tawm nrog ib tug eraser.
2. "Plating" yog tin plating ntawm cov khoom seem. Txoj kev tshwj xeeb yog dip cov tshuaj rosin cawv thiab siv rau ntawm cov khoom seem ntawm cov khoom siv vuam, tom qab ntawd nias lub taub hau kub soldering hlau nrog tin rau nws, thiab tig cov khoom kom sib npaug ntawm cov txheej txheej ntawm tin txheej. Nyob rau hauv cov ntaub ntawv ntawm multi-strand nyob ntawm tej, lawv yuav tsum tau twisted ua ke tom qab polishing, thiab ces tinned.
3. "Testing" yog siv multimeter los xyuas seb qhov zoo ntawm tag nrho cov tin-plated Cheebtsam yog txhim khu kev qha tom qab "plating". Yog tias muaj cov khoom siv tsis raug lossis puas tsuaj, lawv yuav tsum tau hloov nrog cov khoom ntawm tib lub ntsiab lus.
2.2 Tsib kauj ruam ntawm kev ua haujlwm
1. Npaj rau vuam: Tshawb xyuas qhov xwm txheej ntawm cov hluav taws xob soldering hlau. Tom qab paub tseeb tias nws yog lawm, txiav txim siab qhov vuam txoj hauj lwm thiab xyuas cov khoom siv vuam
2. Plug rau hauv thiab preheat qhov vuam txoj hauj lwm: lub hwj chim ntawm cov hluav taws xob soldering hlau, taw tes rau lub taub hau soldering hlau ntawm txoj hauj lwm yuav tsum tau welded, thiab preheat rau 1-2 vib nas this (lub sij hawm preheating nyob ntawm qhov kub ntawm cov hlau soldering siv. thiab qhov kub ntawm cov khoom yuav tsum tau welded
3. Ntxiv tin hlau: Tom qab vuam txoj hauj lwm yog preheated, tuav lub tin hlau nrog koj sab tes laug thiab xa mus rau txoj hauj lwm solder.
4. Disconnect lub tin hlau: Thaum lub tin hlau melts kom tau raws li qhov yuav tsum tau ntawm lub solder sib koom, tshem tawm cov tin hlau.
5. Lub taub hau ntawm cov hlau nplaum tawm ntawm qhov sib koom ua ke: Tom qab ua tiav qhov sib koom ua tiav, tshem tawm cov hlau nplaum thiab muab cov hlau hlau tso rau ntawm qhov muag muag.
