PCB Ultrasonic Ntxuav Tshuab - Jiayuanda Technology
Mar 09, 2022
PCB pawg thawj coj saib xyuas, feem ntau yog siv lub tshuab ntxuav ultrasonic rau kev tu, tab sis muaj cov khoom siv ntawm lub rooj tsav xwm Circuit Court, xws li siv lead ua oscillator, hlau plhaub, tom qab ntxuav, nws yog ib qho nyuaj rau qhuav cov dej noo hauv cov khoom. Siv ultrasonic tu lub hauv paus ntsiab lus: flux residue tu, feem ntau los ntawm kev tawg ntawm qhov ua tiav. Txawm hais tias rosin los yog organic acids thiab lawv cov tin los yog lead ntsev yog soluble nyob rau hauv lub tshuab ntxhua khaub ncaws, tshem tawm cov residues yog ua tiav los ntawm kev xa cov Circuit Court board los ntawm lub tshuab ntxhua khaub ncaws mus rau lub tshuab ntxhua khaub ncaws.
Txoj kev nyab xeeb dua yog siv ultrasonic tu
Kev faib cov seem seem, cov seem ntawm cov ntawv luam tawm Circuit Court tom qab vuam tuaj yeem kwv yees faib ua peb pawg:
1, cov pa phem phem - plua plav, lint thiab pob solder. Solder pob yog qhov tsis xws luag. Yog tias qhov kev vibration ntawm cov cuab yeej ua rau ntau lub pob me me sib sau ua ke hauv ib feem, nws yuav ua rau hluav taws xob luv luv. Cov pob tuaj yeem raug tshem tawm los ntawm kev ntxuav.
2. Tsis yog-polar contaminants -- rosin resin, paraffin wax thiab anti- oxidant roj siv nyob rau hauv yoj soldering, nrog rau cov tshuaj pleev ib ce los yog tshuaj ntxuav tes tso tseg los ntawm cov neeg ua haujlwm.
3, polar av - halides, acids thiab ntsev. Circuit board contamination tej yam tshwm sim: cov pa paug paug -- hluav taws xob luv luv Circuit Court polarity contamination -- dielectric breakdown, to, component/circuit corrosion non-polar contamination cuam tshuam qhov tsos, hmoov dawb taw tes, adhesion plua plav, hluav taws xob tiv tauj tsis zoo PCB, Circuit Court board,
Txoj kev ntxuav ntawm lub rooj tsav xwm hauv Circuit Court yog raws li nram no: (1) Kev tu vaj tse feem ntau yog siv ib lub tank tu, thiab PCB yuav tsum tau ntxuav yog tsau rau hauv cov kua tshuaj ntxuav. Qhov kub ntawm tus neeg saib xyuas hauv lub tshuab ntxuav ultrasonic feem ntau yog teem rau 35 degree -85 degree, thiab lub sijhawm tu yog 3-5 feeb.
