Brown oxidation ntawm cov ntawv luam tawm Circuit Board
Tso lus
Feem ntau hais lus, luam ntawv Circuit Court board tsim muaj ntau yam txheej txheem, ntawm cov kev kho mob browning yog ib kauj ruam tseem ceeb heev. Browning kev kho mob tuaj yeem tshem tawm cov oxide txheej ntawm lub rooj tsavxwm, yog li txhim kho lub cev thiab hluav taws xob, thiab txhim kho kev ntseeg tau thiab ruaj khov ntawm kev sib txuas.
Muaj ntau txoj hauv kev rau luam tawm Circuit Board browning kev kho mob, nrog rau cov tshuaj browning thiab electrochemical browning. Tshuaj browning yog hais txog kev ntub cov ntawv luam tawm hauv cov tshuaj lom neeg tshwj xeeb, ua rau cov oxide txheej tshem tawm ntawm qhov chaw. Txoj kev no yooj yim thiab ua tau, tab sis cov nyhuv txawv. Electrochemical browning yog siv cov tshuaj electrochemical los tshem tawm cov oxide txheej. Txoj kev no yog qhov nyuaj, tab sis cov nyhuv zoo heev, nrog cov neeg siab thiab rov ua dua.
Ntxiv rau qhov sib txawv ntawm cov txheej txheem, kuj tseem muaj qee cov ntsiab lus uas yuav tsum tau them sai sai rau hauv kev coj ua rau xim av oxidation ntawm cov ntawv luam tawm hauv Circuit Court. Piv txwv li, xaiv qhov tsim nyog kub thiab lub sijhawm ua haujlwm los tiv thaiv kev ua haujlwm ntau dhau lossis tsis txaus, uas tuaj yeem cuam tshuam qhov zoo ntawm kev sib txuas. Thaum xaiv cov tshuaj daws teeb meem, yuav tsum tau them nyiaj rau lawv cov corrosiveness. Feem ntau hais lus, cov tshuaj alkaline xws li sodium hydroxide lossis potassium hydroxide tuaj yeem tsim cov txiaj ntsig zoo.
Cov ntsiab lus tswj rau xim av oxidation ntawm cov ntawv luam tawm hauv Circuit Court muaj xws li kev daws teeb meem, lub sijhawm browning, thiab kub. Ua ntej, qhov concentration ntawm cov tshuaj yuav tsum tau tswj nyob rau hauv ib qho chaw tsim nyog. Yog tias qhov concentration siab dhau lawm, nws yuav ua rau tev tawm ntawm qhov chaw ntawm lub rooj tsav xwm luam tawm; Yog tias qhov concentration tsawg dhau, nws yuav cuam tshuam rau cov nyhuv browning. Qhov thib ob, lub sijhawm browning kuj yog qhov tseem ceeb uas yuav tsum tau tswj hwm. Lub sij hawm browning yog luv luv, thiab cov nyhuv kho tsis zoo; Yog hais tias lub sij hawm browning ntev dhau lawm, qhov flatness ntawm cov ntawv luam tawm Circuit Board yuav raug cuam tshuam. Thaum kawg, qhov kub thiab txias kuj yog ib yam uas yuav tsum tau tswj. Kev kub siab dhau los yog qis dhau tuaj yeem cuam tshuam rau cov nyhuv browning, yog li nws yog qhov tsim nyog los tswj nws ntawm qhov kub thiab txias.
