Rau cov dej yaug ntawm cov ntawv luam tawm Circuit Board
Tso lus
Kev ywg dej ntawm cov ntawv luam tawm Circuit Board yog ib txoj hauv kev los ntxuav cov khoom siv hluav taws xob uas tsim tawm. Thaum lub sij hawm tsim cov txheej txheem, qee cov tshuaj thiab cov plua plav tseem nyob rau hauv lub substrate, uas yuav ua rau tsis ua hauj lwm ntawm Circuit Court lossis cuam tshuam rau kev ua haujlwm ntawm cov khoom siv hluav taws xob.
Yog li ntawd, cov dej yaug tuaj yeem tshem tawm cov khoom seem no los ntawm kev siv cov tshuaj ntxuav tshwj xeeb thiab cov dej ntws siab, kom ntseeg tau tias qhov chaw ntawm lub rooj tsav xwm luam tawm tau huv si, yog li txhim kho nws qhov zoo thiab kev ntseeg tau.
Printed circuit board yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob, uas yog lub luag haujlwm ntawm kev sib txuas ntawm Circuit Court thiab teeb liab. Txhawm rau kom ntseeg tau tias qhov zoo thiab kev ruaj ntseg ntev ntawm cov ntawv luam tawm Circuit Board, nws yog ib qho tsim nyog yuav tsum tau ntxuav cov ntawv luam tawm hauv cov txheej txheem ntau lawm.
Cov dej yaug yog xa cov ntawv luam tawm hauv Circuit Court uas tau luam tawm, kub-plated, los yog solder resistance rau hauv lub tshuab ntxhua khaub ncaws. Nws lub hom phiaj yog los ntxuav cov khoom siv tshuaj lom neeg thiab cov plua plav tawm ntawm qhov chaw, kom ntseeg tau tias lub rooj tsav xwm luam tawm tsis muaj roj av, tsis muaj qhov seem, qhuav thiab tsis muaj dej rau kev kho mob ntxiv.
Nyob rau hauv cov txheej txheem dej yaug, cov ntawv luam tawm ntawm lub rooj tsavxwm yuav tsum tau muab ntxuav ua ntej, uas yog, lub rooj tsavxwm yuav muab tso rau hauv lub tank ntxuav, thiab cov tooj liab slag, plua plav yuav raug ntxuav los ntawm kev quab yuam cua. Tom ntej no los tus tswv ntxuav. Cov kauj ruam no yog ua kom lub rooj tsavxwm hauv lub tank tu, los ntawm lub twj tso kua mis tshwj xeeb los cheb cov dej los ntxuav cov av hauv av, emulsion luam ntawv kua, cov kua nplaum seem, thiab lwm yam. ntxuav lub tank hauv qee lub sijhawm kom tshem tawm cov khoom seem ntawm cov dej ntxuav thiab txo qhov cuam tshuam ntawm impurities ntawm cov txheej txheem tom ntej.
Nws yog ib qho tsim nyog sau cia tias cov dej yaug yuav tsum tau siv cov dej zoo deionized, vim tias cov dej deionized tsis muaj ions, cov kab mob thiab cov impurities yog qhov tsim nyog rau kev tsim cov ntawv luam tawm hluav taws xob.
Daim duab: Cov kab ntau lawm ntawm cov dej yaug
Qhov cuam tshuam ntawm kev yaug dej rau qhov zoo muaj xws li cov hauv qab no:
1. Tshem tawm cov khoom seem: Cov txheej txheem pcb tsim yuav tsim ntau yam khoom seem, xws li vuam seem, roj, plua plav thiab lwm yam. Yog tias cov khoom seem no tsis raug ntxuav kom huv si, lawv tuaj yeem cuam tshuam tsis zoo rau kev ua haujlwm thiab kev ntseeg siab ntawm lub rooj tsavxwm. Kev ntxhua khaub ncaws tuaj yeem tshem tawm cov khoom seem, yog li ua kom lub rooj tsavxwm zoo.
2. Zam tsis txhob luv luv Circuit Court: muaj ntau cov ntsiab lus me me ntawm lub rooj tsav xwm luam tawm, thiab yog tias muaj cov pa phem ntawm cov ntsiab lus txuas no, nws yuav ua rau muaj teeb meem luv luv. Cov kab mob no tuaj yeem raug tshem tawm los ntawm kev ntxuav kom tsis txhob muaj qhov tshwm sim luv luv.
3.Ua kom lub ntsej muag tiav ntawm lub rooj tsav xwm luam tawm: Qhov kawg ntawm lub pcb muaj qhov cuam tshuam loj rau nws qhov kawg tshwm sim thiab kev ua tau zoo. Yog tias muaj cov stains thiab qhov tsis xws luag ntawm qhov chaw ntawm lub rooj tsav xwm luam tawm, nws yuav cuam tshuam rau nws cov khoom kawg thiab kev sib tw ua lag luam. Kev yaug dej tuaj yeem ua kom lub ntsej muag du ntawm lub rooj tsav xwm luam tawm.
4.Ua kom ntseeg tau tias cov hluav taws xob ua haujlwm ntawm pcb: Yog tias muaj cov pa phem thiab cov khoom seem ntawm lub rooj tsavxwm, nws yuav muaj kev cuam tshuam tsis zoo rau nws cov khoom siv hluav taws xob. Los ntawm kev yaug dej, cov pa phem thiab cov khoom seem tuaj yeem raug tshem tawm, ua kom cov hluav taws xob ua haujlwm ntawm pcb.
Kev ywg dej yog ib qho tseem ceeb hauv kev tsim cov ntawv luam tawm Circuit Board. Piv nrog rau lwm cov txheej txheem, cov txheej txheem dej yaug yog qhov yooj yim, tab sis cov txheej txheem muaj lub luag haujlwm tseem ceeb hauv qhov zoo ntawm pcb, thiab yog ib qho tseem ceeb lav ntawm qhov zoo ntawm cov ntawv luam tawm Circuit Board.
