Dab tsi yog kev npaj rau kev siv cov hlau soldering?
1. Ua ntej yuav siv ib tug tshiab soldering hlau, polish lub taub hau nrog zoo sandpaper, ua kom sov nws nrog hluav taws xob, dipped nyob rau hauv rosin thiab kov cov hniav ntawm lub ntsis mus rau lub soldering hlau kom sib npaug ntawm lub taub hau nrog ib txheej ntawm tin. Ua li no tuaj yeem pab txhawb kev sib koom tes thiab tiv thaiv qhov chaw ntawm cov hlau taub hau los ntawm oxidizing. Yog hais tias lub qub qub hlau taub hau yog oxidized heev thiab tig dub, koj tuaj yeem siv cov ntawv hlau los tshem tawm cov oxide saum npoo kom nthuav tawm cov xim hlau, thiab tom qab ntawd rov tin plating nws ua ntej siv.
Cov hlau nplaum yuav tsum muaj 220V AC fais fab mov, yog li ua tib zoo saib xyuas kev nyab xeeb thaum siv nws. Cov ntsiab lus hauv qab no yuav tsum ua tib zoo ua:
Nws yog qhov zoo tshaj plaws los siv peb-ncej ntsaws rau lub vuam hlau ntsaws. Xyuas kom lub enclosure yog grounded zoo.
Ua ntej siv, ua tib zoo xyuas seb lub hwj chim ntsaws thiab lub hwj chim qaum puas puas lawm. Thiab xyuas seb lub taub hau hlau puas yog xoob.
Thaum siv cov hlau soldering, tsis txhob ntaus nws nyuaj. Ceev faj tsis txhob poob. Yog hais tias muaj ntau dhau ntawm lub taub ntawm cov hlau soldering, so nws nrog ib daim ntaub. Tsis txhob muab pov tseg kom tsis txhob hlawv lwm tus.
Thaum lub sij hawm vuam txheej txheem, cov hlau soldering tsis tuaj yeem sab laug nyob ib puag ncig. 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 tsis tuaj yeem muab tso rau ntawm lub taub hau ntawm lub taub hau kom tiv thaiv cov txheej txheem rwb thaiv tsev los ntawm kev kub hnyiab thiab ua rau muaj kev sib tsoo.
Tom qab siv, lub hwj huam mov yuav tsum tau txiav tam sim ntawd thiab lub hwj chim plug yuav tsum tau unplugged. Tom qab txias, muab cov hlau nplaum rov qab rau hauv lub thawv cuab yeej.
2. Solder thiab flux
Thaum vuam, solder thiab flux kuj tseem xav tau.
(1) Solder: Rau vuam cov khoom siv hluav taws xob, feem ntau siv cov hlau nplaum nrog cov rosin core. Qhov no hom ntawm solder hlau muaj ib tug qis melting point thiab muaj rosin flux, ua rau nws yooj yim heev rau siv.
(2) Flux: Feem ntau siv flux yog rosin lossis rosin dej (solve rosin hauv cawv). Kev siv cov flux tuaj yeem pab tshem tawm cov oxides ntawm cov hlau saum npoo, ua kom yooj yim soldering, thiab tiv thaiv cov hlau taub hau. Solder paste kuj tseem siv tau thaum soldering cov khoom loj lossis cov xov hlau. Txawm li cas los xij, nws yog corrosive rau ib qho twg, thiab cov seem yuav tsum tau muab tshem tawm tam sim tom qab vuam.
3. Cov cuab yeej pabcuam
Txhawm rau kom yooj yim rau kev ua haujlwm vuam, rab koob-qhov ntswg pliers, offset pliers, tweezers, thiab riam feem ntau yog siv los ua cov cuab yeej pabcuam. Koj yuav tsum kawm siv cov cuab yeej no kom raug.
