PCBA Circuit Board welding disc dub teeb meem yog ib qho tshwm sim ntau dua Circuit Court board phem tshwm sim, ua rau PCBA vuam disc dub rau ntau yam, tab sis feem ntau tshwm sim los ntawm cov hauv qab no yog vim li cas:
1, ncoo oxidation: Yog tias PCBA ncoo raug cov av noo ntev ntev, nws yuav ua rau lub ncoo oxidize, tsim cov oxide zaj duab xis rau saum npoo ntawm lub ncoo, ua rau dub, yog li ntawd, thaum khaws cia PCBA, kev saib xyuas yuav tsum tau them nyiaj rau kev ua kom ib puag ncig qhuav, thiab tib lub sijhawm, PCBA yuav tsum tau nqus dej hauv lub sijhawm kom tsis txhob raug huab cua mus ntev!
2, vuam txheej txheem teeb meem: nyob rau hauv reflow vuam los yog yoj soldering, yog hais tias lub vuam kub yog siab dhau los yog lub vuam lub sij hawm ntev dhau lawm, nws kuj yuav ua rau oxidation ntawm vuam pad dub tshwm sim, qhov tshwm sim no feem ntau yog vim lub vuam. Qhov kub siab tshaj qhov ntsuas kub tau pom zoo ntawm cov solder, ua rau cov txheej txheem oxidation nrawm, yog li hauv cov txheej txheem vuam yuav tsum ua raws li kev ua haujlwm tshwj xeeb rau vuam!
3, solder teeb meem: solder feem ntau yog hais txog solder paste, tin, solder zoo los yog phem, yog hais tias siv cov tsis zoo solder, kuj yuav ua rau cov solder nyob rau hauv cov teeb meem tshuaj thiab impurities tso tawm, ua rau dub ncoo, yog li, nyob rau hauv kev xaiv ntawm solder, peb yuav tsum tsis txhob siv cov uas tsis zoo solder!
4, kev tu cov teeb meem: Feem ntau hais lus, nyob rau hauv cov ntaub ntawv ntawm kev siv cov flux yuav tsum tau ntxuav lub rooj tsavxwm, thiaj li yuav tshem tawm cov flux residue ntawm lub ncoo, thiab yog hais tias cov flux residue tsis tag nrho tshem tawm, ces cov residual flux yuav degrade. los yog carbonize ntawm qhov kub thiab txias, kom lub ncoo zoo nkaus li dub. Yog li ntawd, kev tu lub sijhawm tom qab vuam yog qhov tsim nyog heev!
5, cov teeb meem ntawm cov khoom siv hluav taws xob: yog tias qhov zoo ntawm cov khoom siv hluav taws xob tsis zoo, lossis cov khoom siv ntawm cov khoom siv hluav taws xob tsis raug, nws kuj tseem tuaj yeem ua rau muaj qhov tshwm sim ntawm cov vuam vuam dub, yog li, thaum xaiv cov khoom siv hluav taws xob, peb yuav tsum xaiv cov khoom zoo. cov khoom siv los xyuas kom meej tias qhov zoo ntawm cov txheej thiab cov khoom siv pin ntawm cov khoom tsim nyog.
Cov saum toj no yog qhov laj thawj tseem ceeb rau PCBA vuam tais dub, thiab raws li cov laj thawj sib txawv, peb tuaj yeem xaiv cov kev txhim kho zoo sib xws, txhawm rau txo qhov teeb meem ntawm PCBA vuam tais dub, txhim kho cov khoom zoo!
