Yuav ua li cas siv hluav taws xob soldering hlau rau beginners
Hluav taws xob soldering hlau yog feem ntau siv vuam cuab yeej. Peb siv 20W sab hauv cua sov hluav taws xob soldering hlau.
Ua ntej siv cov hlau nplaum tshiab, siv cov ntawv xuab zeb zoo los txhuam cov hlau nplaum, ua kom sov nrog hluav taws xob, poob rau hauv rosin, thiab tom qab ntawd hu rau cov hlau nplaum nrog rau ntawm ntug ntawm cov hlau taub hau kom sib npaug ntawm cov hlau taub hau nrog ib qho kev sib tw. txheej tin. Qhov no tuaj yeem pab txhawb kev vuam thiab tiv thaiv qhov chaw oxidation ntawm lub taub hau hlau. Yog hais tias lub qub soldering hlau taub yog hnyav heev oxidized thiab tig dub, qhov saum npoo oxide tuaj yeem raug tshem tawm nrog cov ntaub ntawv hlau kom nthuav tawm nws cov xim hlau, thiab tom qab ntawd rov tinned ua ntej siv.
Lub tshuab hluav taws xob yuav tsum tau siv los ntawm 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 tau ua tiag tiag:
Nws yog qhov zoo tshaj plaws los siv peb tus ncej ntsaws rau lub vuam hlau ntsaws. Xyuas kom cov av zoo ntawm lub casing.
Ua ntej siv, ua tib zoo xyuas lub hwj chim ntsaws thiab lub hwj chim qaum kom puas. Thiab xyuas seb lub taub hau hlau yog xoob.
Thaum siv hluav taws xob soldering hlau, tsis txhob siv quab yuam los ntaus nws. Tiv thaiv kom tsis txhob ntog. Thaum muaj solder ntau dhau ntawm lub taub hau ntawm lub taub hau, nws tuaj yeem wiped tawm nrog ib daim ntaub. Tsis txhob muab pov tseg kom tsis txhob scalding lwm tus.
Thaum lub sij hawm vuam txheej txheem, cov hlau soldering yuav tsum tsis txhob muab tso rau random. Thaum tsis yog soldering, nws yuav tsum tau muab tso rau ntawm lub soldering hlau tuav. Ceev faj tsis txhob muab cov hlua hluav taws xob tso rau ntawm lub taub hau taub hau kom tsis txhob muaj xwm txheej tshwm sim los ntawm scalding txheej rwb thaiv tsev.
Tom qab siv, lub hwj chim yuav tsum raug txiav tawm raws sij hawm thiab lub hwj chim ntsaws yuav tsum tau muab tshem tawm. Tom qab txias, muab cov hlau soldering los ntawm lub toolbox.
2. Solder thiab flux
Thaum vuam, solder thiab flux kuj yuav tsum tau.
(1) Soldering: Soldering cov khoom siv hluav taws xob, feem ntau yog siv cov hlau nplaum nrog cov rosin core. Hom ntawm cov hlau no muaj qhov tsis tshua muaj melting point thiab muaj rosin flux, ua rau nws yooj yim heev rau siv.
(2) Flux: Feem ntau siv flux yog rosin lossis rosin naj hoom (dissolved hauv cawv). Kev siv cov flux tuaj yeem pab tshem tawm cov oxides ntawm cov hlau saum npoo, ua kom yooj yim vuam, thiab tiv thaiv cov hlau taub hau. Thaum vuam cov khoom loj dua los yog cov xov hlau, cov tshuaj txhuam hniav tuaj yeem siv tau. Tab sis nws muaj qee qhov corrosiveness, thiab cov residues yuav tsum tau muab tshem tawm tam sim tom qab vuam.
3. Cov cuab yeej pabcuam
Rau qhov yooj yim ntawm kev ua haujlwm vuam, taw tes qhov ntswg pliers, offset pliers, tweezers, thiab riam me me feem ntau yog siv los ua cov cuab yeej pab. Koj yuav tsum kawm siv cov cuab yeej no kom raug.

Kev kho mob ua ntej weld
Ua ntej welding, thaj tsam ntawm cov khoom siv pins lossis Circuit Court boards yuav tsum tau kho ua ntej vuam.
1. Tshem tawm cov oxide txheej ntawm qhov chaw vuam
Ib rab riam me me tuaj yeem ua los ntawm cov hniav tawg. Tshem tawm cov oxide txheej ntawm cov hlau lead kom nthuav tawm cov xim hlau ntawm tus pin.
Cov ntawv luam tawm hauv Circuit Court tuaj yeem polished nrog cov ntaub nplaum zoo thiab coated nrog ib txheej ntawm rosin cawv tov.
2. Tin plating ntawm cov khoom
Tin lub scraped leads. Tom qab dipping cov hlau lead hauv rosin cawv tov, nias lub kub soldering hlau taub hau nrog tin mus rau cov hlau lead thiab tig nws. Qhov no tuaj yeem sib npaug ntawm cov txhuas nrog ib txheej nyias ntawm tin. Ua ntej vuam cov hlau, cov tawv nqaij rwb thaiv tsev yuav tsum tau tev tawm thiab tom qab ntawd raug rau ob qho kev kho saum toj no ua ntej nws tuaj yeem raug welded. Yog hais tias cov hlau yog ua los ntawm ntau cov hlua hlau hlau, nws yuav tsum tau sib tw ua ntej tin plating tom qab polishing.
