PCBA board ntxuav txheej txheem
Raws li qhov sib txawv ntawm cov fluxes siv hauv cov khoom siv hluav taws xob luam tawm, cov txheej txheem ntxuav dej tuaj yeem muab faib ua saponified dej tu thiab ntxuav dej huv.
(1) Saponified dej tu txheej txheem. Rau cov khoom siv hluav taws xob luam tawm nrog cov rosin flux, yuav tsum siv cov txheej txheem ntxuav saponification. Qhov no yog vim lub ntsiab ntawm rosin, rosin acid, yog insoluble nyob rau hauv dej, thiab dej yuav tsum tau siv raws li ib tug hnyav. , tuaj yeem tshem tawm cov rosin fatty acid, thiab thaum kawg ntxuav nrog dej huv kom ua tiav lub hom phiaj ntawm kev ntxuav.
(2) Cov txheej txheem ntxuav dej huv. Kev ntxuav cov dej huv yog siv cov dej huv los yog dej ntshiab rau kev ntxuav thiab yaug. Piv nrog rau cov txheej txheem ntxuav dej saponified, cov dej huv huv yog tsim rau cov khoom siv hluav taws xob uas muaj cov dej-soluble flux.
Baiqiancheng tau nyob hauv PCBA kev lag luam rau ntau tshaj 18 xyoo, thiab tau tsom mus rau kev tswj cov txheej txheem tsim khoom, nruj me ntsis tswj txhua qhov txuas ntawm kev tsim khoom, thiab xyuas kom meej tias qhov kev ntsuam xyuas muaj tseeb ua ntej xa mus rau cov neeg siv khoom. Baiqiancheng them nyiaj zoo rau qhov zoo ntawm PCBA ntau lawm. nruj me ntsis tswj cov txheej txheem ntxuav PCBA
