Thaum lub sij hawm soldering txheej txheem ntawm Cirtral Board, yuav tsum tau ua kev ceev faj, txwv tsis pub nws yooj yim los ua kev puas tsuaj rau PCB board lossis Cheebtsam. Yog li dab tsi yog cov txheej txheem vuam rau luam tawm cov boardcuit Coffs? Vuam txheej txheem thiab kev ceev faj rau luam tawm cov laug cam cov laug cam (PCBs):
1. VUAM Cov Ntaub Ntawv
(1) Solder: Feem ntau, Sn63 solder uas ua tau raws li tus qauv Asmeskas
(2) flux: feem ntau rosin flux lossis dej-soluble flux tuaj yeem siv, tom kawg yog feem ntau tsuas yog siv rau yoj soldering.
(3) Tus neeg saib xyuas tu: nws yuav tsum ua kom paub tseeb tias tsis muaj xeb lossis muaj kuab paug rau cov ntawv luam tawm Circuit Court. Feem ntau, ntxuav cov neeg sawv cev xws li ethanol (kev siv dej cawv), yog ooprotrifluoroethane, iSopropanol (iS Aviation Ntxuav roj av, thiab dej deionized siv rau kev ntxuav. Tus neeg saib xyuas tu kom tau siv rau kev ntxuav tu yuav tsum tau raug xaiv raws li cov txheej txheem tseev kom muaj.
2. VUAM cov cuab yeej thiab khoom siv
(1) Kev xaiv tsim nyog ntawm lub zog thiab hom hluav taws xob tshuab hluav taws xob yog ncaj qha rau kev txhim kho vuam zoo thiab ua haujlwm tau zoo. Nws raug nquahu kom siv qhov tsawg-voltage kub tswj cov hlau soldering hlau. Lub taub hau hlau sib dhos tuaj yeem ua los ntawm Nickel Plated, Plated cov ntaub ntawv, thiab cov duab yuav tsum raug txiav txim siab raws li kev xav tau kev xav tau raws li kev xav tau vuam xav tau.
(2) yoj soldering tshuab thiab ua kom sflash soldering tshuab yog ib qho ntawm cov cuab yeej vuam haum rau kev tsim khoom loj.
3. Npaj ua ntej vuam
(1) Kuaj xyuas yog tias tus qauv, cov lus qhia tshwj xeeb, thiab ntau ntawm cov cheebtsam ua raws li cov npe sib koom ua ke.
(2) Vuam cov neeg ua haujlwm yuav tsum hnav cov dab teg tawm tsam thiab paub meej tias cov kub tsis tu ncua solding hlau yog qhov av.
4. VUAM QIB
Qhov kev sib tw vuam ntawm cov Cheebtsam yog lub peev xwm, catchitor, tryode, sib xyaw ua ke, thiab lwm yam yog thawj me me thiab tom qab ntawd loj.
5. VUAM Txheej Txheem Flow
Cov txheej txheem vuam ntawm cov ntawv luam tawm hluav taws xob feem ntau yuav tsum muaj phau ntawv ntxig, kev tuav ntaub ntawv, thiab tshuaj ntsuam. Cov kauj ruam dav dav yog raws li hauv qab no:
(1) Xaiv tus qauv sib raug ua raws li cov haujlwm tsim khoom, thiab tshawb xyuas seb tus qauv ntawm cov chaw xa khoom tuaj yeem raug puas tsuaj raws li BOM.
(2) Kuaj xyuas yog tias cov npoo ntawm cov ntawv luam tawm Circuit Court yog huv, cov roj stains, pub dawb yog tias nws tsis huv, siv dej cawv los ntxuav nws kom zoo. Tom qab tu, tos kom muaj cawv kom yaj ua ntej vuam.
(3) Xaiv cov khoom sib raug raws li cov foob pob, thiab ua tib zoo xyuas cov qauv thiab kom muaj nuj nqis ntawm cov khoom siv. Nyob rau tib lub sijhawm, xyuas seb puas muaj kev puas tsuaj lossis xeb cim rau saum npoo thiab pins ntawm cov khoom uas cuam tshuam lawv qhov kev ua tau zoo.
(4) Tom qab paub tseeb tus qauv thiab kom muaj nuj nqis ntawm cov khoom siv thiab cov khoom siv hluav taws xob, ntxig cov khoom siv rau hauv cov ntawv sib dhos raws li BOM thiab txoj haujlwm ntawm Circuit Courruit Board.
(5) WELD TXHUA TXHUA TXHUA YAM RAWS LI TXOJ CAI YUAV TSUM TAU TXAIS KEV YUAV TSUM TAU TXAIS LOSSIS TSIS TXAUS SIAB RAU LUB CAIJ
(6) txiav tawm ntau dua pins tom qab vuam.
(7) Kuaj cov ntsiab lus vuam rau txhua qhov tsis yog, thiab yog tias muaj, kho lawv.
(8) Tom qab vuam, cov ntawv luam tawm cov board yuav tsum tau huv kom huv si kom tshem tawm cov khoom seem flux, cov roj av thiab lwm cov kuab paug. Cov txheej txheem kev ntxuav huv tshwj xeeb yog nqa tawm raws li cov txheej txheem tseev kom muaj.
