Yuav ua li cas siv ib tug taw tes soldering hlau thiab ib co tswv yim yuav ua li cas siv ib tug taw tes soldering hlau
Kev npaj
1. Ua ntej siv cov hlau nplaum tshiab, daim ntawv thov ntawm cov ntawv xuab zeb zoo yuav yog lub taub hau hlau ci, hluav taws xob cua sov, dipped nyob rau hauv rosin nrog ib tug soldering hlau taub hau ntug hu rau solder hlau, kom lub taub hau hlau tusyees coated nrog ib tug txheej ntawm tin. Ua li no, tuaj yeem ua kom yooj yim vuam thiab tiv thaiv qhov chaw ntawm lub taub hau hlau oxidation. Yog hais tias lub taub hau qub hlau yog oxidized thiab blackened, siv ib tug steel ntxhov siab los yog hlau nqus tsev vacuum los ua rau cov oxide deg, thiaj li hais tias nws nthuav tawm ib tug metallic luster, re-plated nrog tin, ua ntej siv.
Cov hlau nplaum yuav tsum tau siv nrog 220V AC fais fab mov, thiab tshwj xeeb yuav tsum tau them nyiaj rau kev nyab xeeb thaum siv nws. Cov ntsiab lus hauv qab no yuav tsum ua tib zoo ua:
Nws yog qhov zoo dua los siv peb-ncej ntsaws ntawm cov hlau soldering. Ua lub plhaub kom zoo hauv av.
Ua ntej siv, lub hwj chim ntsaws thiab lub hwj chim qaum yuav tsum tau ua tib zoo xyuas seb puas muaj kev puas tsuaj. Thiab xyuas seb lub taub hau hlau soldering puas xoob.
Nyob rau hauv kev siv ntawm cov hlau soldering, nws yuav tsum tsis txhob khob nrog quab yuam. Tiv thaiv kom tsis txhob ntog. Thaum muaj solder ntau dhau ntawm lub taub hau ntawm cov hlau soldering, nws tuaj yeem wiped tawm nrog ib daim ntaub. Tsis txhob nplawm nws ib ncig kom tsis txhob hlawv lwm tus.
Thaum lub sij hawm vuam txheej txheem, cov hlau soldering tsis tuaj yeem muab tso rau txhua qhov chaw. Thaum tsis yog soldering, nws yuav tsum tau muab tso rau ntawm lub soldering hlau sawv ntsug. Nco ntsoov tias cov hlua hluav taws xob yuav tsum tsis txhob raug ntaus rau lub taub hau ntawm cov hlau soldering, txhawm rau tiv thaiv scalding lub rwb thaiv tsev txheej thiab xwm txheej.
Tom qab siv qhov kawg, yuav tsum tau txiav tawm raws sijhawm, tshem tawm lub hwj chim ntsaws. Tom qab txias, ces cov hlau soldering rov qab mus rau lub thawv cuab yeej.
2, Solder thiab flux
Vuam, tab sis kuj yuav tsum tau solder thiab flux.
(1) solder: vuam cov khoom siv hluav taws xob, feem ntau siv nrog rosin core ntawm cov hlau solder. Cov hlau no, qis melting point, thiab muaj rosin flux, yooj yim heev rau siv.
3, cov cuab yeej pabcuam
Txhawm rau kom yooj yim rau kev ua haujlwm vuam yog feem ntau siv cov ntse-nosed pliers, ib nrab lub qhov ncauj pliers, tweezers thiab riam ua cov cuab yeej pabcuam. Yuav tsum kawm siv cov cuab yeej no kom raug.

Ua ntej soldering
Ua ntej vuam, yuav tsum yog cov khoom siv pins lossis Circuit Court board vuam qhov chaw ntawm kev kho ua ntej.
1, tshem tawm cov vuam qhov chaw ntawm oxide txheej
Muaj tawg saw hniav ua los ntawm riam. Scrape saum npoo ntawm cov hlau lead oxide txheej, kom cov pins nthuav tawm cov luster ntawm cov hlau.
Cov ntawv luam tawm tuaj yeem siv tau zoo gauze ntawv yuav yog tooj liab ntawv tom qab ua si lub teeb, coated nrog ib txheej ntawm rosin cawv tov.
2, khoom tinning
Nyob rau hauv lub scraping ntawm lub net lead ntawm lub tin. Cov txhuas tuaj yeem dipped rau hauv cov tshuaj rosin cawv, cov hlau kub kub nrog cov tin taub hau siab ntawm cov hlau lead, thiab tig cov hlau lead. Yuav ua rau cov hmoov txhuas sib npaug plated nrog ib txheej nyias ntawm tin. Ua ntej welding cov hlau lead, lub insulating sheath yuav tsum tau stripped, thiab tom qab ntawd tom qab ob txoj kev kho saum toj no, ua ntej kev vuam. Yog hais tias nws yog ib tug multi-stranded hlau leads, lightening yuav tsum tau screwed ua ntej, thiab ces tinned.
