Cov ntsiab lus tseem ceeb ntawm Kev Siv Hluav Taws Xob Hluav Taws Xob Hlau Vuam Tshuab
1. Vuam txoj kev
Vuam, tshuaj xyuas, thiab txiav luv luv
Tuav lub tshuab hluav taws xob ntawm sab tes xis thiab siv lub qhov ntswg pliers lossis tweezers rau clamp cov khoom lossis cov xov hlau ntawm sab laug tes; Ua ntej welding, cov hlau soldering yuav tsum tau preheated tag nrho, thiab cov hniav saum npoo ntawm cov hlau taub hau yuav tsum tau coated nrog solder, uas yog, ib co ntawm cov solder yuav tsum tau ntxiv.
Muab lub hau ntawm cov hlau nplaum nruj nreem rau ntawm qhov sib koom ua ke, nrog cov hlau nplaum ntawm lub kaum sab xis ntawm kwv yees li 60 ° C mus rau lub dav hlau kab rov tav, kom cov tin melted ntws los ntawm lub taub mus rau qhov sib koom ua ke. Tswj lub sij hawm ntawm cov hlau taub hau nyob ntawm qhov sib koom ua ke rau 2-3 vib nas this.
Nqa lub taub hau ntawm cov hlau thiab tuav cov khoom ntawm koj sab laug kom txog thaum lub tin ntawm qhov sib koom ua ke txias thiab khov ua ntej tso koj sab laug tes.
Siv cov tweezers tig cov hlau lead kom paub meej tias nws tsis xoob, thiab tom qab ntawd siv cov cutters los txiav tawm cov hlau lead ntau dhau.
2. Vuam zoo
Thaum vuam, nws yog ib qho tsim nyog los xyuas kom meej tias txhua qhov chaw vuam yog ruaj khov thiab muaj kev sib cuag zoo, thiab ua kom cov vuam zoo.
Ib tug zoo solder sib koom yuav tsum muaj ib tug kaj, du thiab burr dawb solder chaw, nruab nrab ntawm solder, ruaj fusion ntawm solder thiab cov khoom raug welded, thiab tsis muaj virtual los yog cuav soldering. Virtual soldering yog hais txog qhov xwm txheej uas tsuas yog ib qho me me ntawm cov solder txuas mus rau qhov sib koom ua ke, ua rau muaj kev sib cuag tsis zoo thiab tsis sib xws.
Fake soldering yog hais txog qhov xwm txheej uas nws zoo li yuav tsum tau soldered ntawm qhov chaw, tab sis qhov tseeb nws tsis yog soldered. Qee zaum, los ntawm manually rub tawm cov hlau lead, nws tuaj yeem raug tshem tawm los ntawm kev sib koom ua ke. Ob qhov xwm txheej no yuav ua rau muaj teeb meem loj rau kev debugging thiab kev saib xyuas ntawm cov khoom siv hluav taws xob. Tsuas yog los ntawm kev siv dav dav thiab hnyav hnyav tuaj yeem zam ob qhov xwm txheej no.
Thaum soldering Circuit Court boards, nws yog ib qho tseem ceeb los tswj lub sij hawm. Yog tias lub rooj tsav xwm Circuit Court ntev dhau lawm, nws yuav hlawv lossis ua rau cov ntawv ci tooj liab tev tawm. Thaum disassembling Cheebtsam los ntawm lub rooj tsavxwm Circuit Court, koj tuaj yeem tso cov hlau nplaum rau ntawm qhov sib koom ua ke thiab tos kom lub tin ntawm cov khoom sib txuas kom yaj ua ntej rub tawm cov khoom.
Flux (rosin thiab soldering roj) yog qhov tseem ceeb thaum lub sij hawm vuam. Cov rosin tshiab thiab cov roj uas tsis muaj corrosive tuaj yeem pab koj ua tiav qhov vuam zoo thiab ua kom lub ntsej muag du thiab zoo nkauj. Koj tuaj yeem siv ntau flux thaum siv nws.
