PCB Circuit Boards tau siv dav hauv Suav teb, thiab cov pa phem yuav raug tsim tawm thaum lub sijhawm tsim khoom ntawm cov ntawv luam tawm Circuit Board, suav nrog cov plua plav thiab cov khib nyiab hauv cov txheej txheem tsim khoom xws li cov khoom seem ntawm flux thiab cov nplaum.Yog tias lub rooj tsavxwm pcb tsis tuaj yeem lav qhov huv si, qhov kev tiv thaiv thiab cov dej xau yuav ua rau lub rooj tsavxwm pcb tsis ua haujlwm, yog li cuam tshuam rau lub neej kev pabcuam ntawm cov khoom.Yog li ntawd, ntxuav lub pcb Circuit Court board thaum lub sij hawm tsim khoom yog ib qho tseem ceeb kauj ruam.
Semi-aqueous tu feem ntau yog siv cov kuab tshuaj organic thiab dej deionized, ntxiv rau qee yam ntawm cov tshuaj nquag thiab cov khoom ntxiv.Qhov kev ntxuav no yog nruab nrab ntawm cov kuab tshuaj ntxuav thiab ntxuav dej.Cov tshuaj ntxuav tes no yog cov kuab tshuaj organic, cov kuab tshuaj tsw qab, lub teeb nyem siab, tsis muaj tshuaj lom, thiab siv tau zoo, tab sis yuav tsum tau muab yaug nrog dej thiab tom qab ntawd cua qhuav.

Kev siv thev naus laus zis dej huv yog txoj kev txhim kho ntawm kev siv tshuab huv yav tom ntej, thiab nws yog qhov tsim nyog los tsim kom muaj cov dej ntshiab huv thiab tshem tawm cov dej kho dej.Siv dej ua qhov nruab nrab ntxuav, ntxiv surfactants, additives, corrosion inhibitors thiab chelating agents rau dej los tsim ib tug series ntawm cov dej-raws li tshuaj ntxuav.Cov kuab tshuaj aqueous thiab cov khoom tsis huv tuaj yeem raug tshem tawm.

Nws yog siv nyob rau hauv cov txheej txheem soldering tsis tu flux los yog solder paste.Tom qab soldering, nws mus ncaj qha mus rau cov txheej txheem tom ntej rau kev tu, tsis pub dawb tu tshuab yog tam sim no feem ntau siv lwm txoj kev siv tshuab, tshwj xeeb tshaj yog cov khoom siv sib txuas lus hauv xov tooj yog ib qho kev siv ib zaug los hloov ODS.Cov kuab tshuaj ntxuav yog tsuas yog siv rau cov kuab tshuaj dissolution kom tshem tawm cov kab mob.Kev ntxuav cov kuab tshuaj yuav tsum tau siv cov cuab yeej yooj yim vim nws cov volatilization ceev thiab muaj zog solubility.
