Taw qhia rau 5- theem deg txoj kev soldering nrog solding hlau
Kauj ruam 1: Npaj vuam cov ntaub ntawv
Ua ntej tshaj plaws, peb yuav tsum npaj cov ntaub ntawv vuam, xws li soldering hlau, camer cov hlau, cov hlau, thiab flux. Ntxiv nrog rau thawj txheej txheem, peb kuj yuav tsum tau siv cov hlau cam thiab cov hlau hlau. Feem ntau, peb siv peb sab tes sab xis los tuav cov hlau solding thiab sab tes laug tuav cov hlau solder. Peb mam li nruab cov cheebtsam rau hauv PCB thiab muab lawv tso rau saum rooj rau soldering. Them sai sai rau qhov kub ntawm cov cam tov tom qab cua sov rau ib lub sijhawm. Tsis txhob kov nws nrog koj txhais tes, txwv tsis pub nws yuav ua rau kub hnyiab.
Kauj ruam 2: Thaum tshav kub lub vuam
Tom qab cua sov cov soldering hlau, nws yog qhov zoo tshaj plaws kom tso nws hauv flux rau ib pliag. Nws yuav zoo dua yog tias qee qhov flux tuaj yeem raug ntxiv rau thaj chaw soldering, uas ua rau nws harder. Thaum soldering sib txuas rau thaj ua rau thaj, peb muaj kev nkag siab zoo dua ntawm qhov tsim nyog ntawm kev ntxiv flux. Cov hlau cam tsis tas yuav muab tso rau hauv flux ntev ntev, li ntawm ob lub vib nas this.
Kauj ruam 3: Ntxiv Cov Ntaus Hlau
Tom qab solding hlau ncav cuag ib qho kub thiab txias, peb pib siv lub zog. Ua ntej, tso cov hlau cam ntawm cov pins ntawm cov hlau sib xyaw, tom qab ntawd tuav cov hlau solding, thiab tom qab solder cov tshuaj muaj peev xwm nyob ib puag ncig ntawm cov pins ntawm cov khoom siv. Thaum soldering Congterated Chips, ceevfaj tsis txhob ntxiv ntau dhau molding.
Kauj ruam 4: Tshem tawm cov hlau cam
Tom qab cov ham tau melts thiab drips mus rau hauv cov cheebtsam yuav tsum soldered, peb tau ua tiav ib nrab ntawm peb txoj haujlwm. Cov kauj ruam tom ntej yog tos rau cov hlua hlau kom muaj txiaj ntsig, yog li tsis tas yuav tso cov hlau khi rau ntawm cov tshuab soldering ntxiv lawm. Peb yuav tsum txav kom sai li sai tau tawm ntawm rab riam yog li ntawd cov hlua khau tuaj yeem ua kom khov kho.
KAUJ RUAM 5: Tshem tawm cov tub rog sib dhos
Tom qab tshem tawm cov hlau cam, txhawm rau ua kom zoo nkauj dua ntawm thawj qhov xwm txheej ntawm cov ntawv sib dhos, kom zam dhau qhov tshwm sim ntawm cov ntawv sib dhos los ntawm cov hlau tsis txaus. Thaum nqa tawm cov haujlwm tiag tiag, tsis txhob tso cov cam hlau cam ntawm thaj chaw yuav tsum tau soldered rau lub sijhawm ntev. Yog tias cov hlua hlau khi ntau dhau lawm siab dhau, nws yuav ua rau cov hlua khi kom poob, uas yuav ua rau tus kab mob PCB tau raug nyem.
