Nyob rau hauv niaj hnub electronics manufacturing, cov txheej txheem ntau lawm ntawm PCB Circuit Boards txiav txim siab qhov ua tau zoo thiab kev ntseeg siab ntawm cov khoom. Ntawm lawv, cov txheej txheem kev txhim kho yog qhov txuas tseem ceeb hauv cov txheej txheem tsim khoom PCB, uas cuam tshuam ncaj qha rau qhov tseeb thiab qhov tseeb ntawm cov duab kos duab hauv Circuit Court. Yog li ntawd, kev nkag siab txog cov txheej txheem kev loj hlob kuj tseem yuav pab tau txhua tus neeg kom nkag siab zoo txog lub zog tag nrho ntawm PCB Circuit Board board manufacturers.

IB 、 Kev tsim kho txheej txheem txheej txheem
Cov txheej txheem kev loj hlob yog hais txog cov txheej txheem uas cov khoom siv photosensitive (feem ntau yog cov yeeb yaj kiab qhuav photoresist lossis cov yeeb yaj kiab ntub dej photoresist) coated ntawm cov substrate raug nthuav tawm thiab tom qab ntawd cov khoom tsis raug tshem tawm los ntawm cov neeg tsim tshuaj lom neeg thaum lub sij hawm tsim khoom PCB. Lub hom phiaj ntawm cov txheej txheem no yog khaws cia cov chaw tshwj xeeb ntawm cov khoom siv photosensitive, yog li tsim cov qauv hauv Circuit Court hauv kev npaj rau cov txheej txheem etching tom ntej.

ﺌ 、 Cov kauj ruam hauv txoj kev txhim kho
Hauv PCB circuit board manufacturers, txoj kev txhim kho feem ntau suav nrog cov kauj ruam hauv qab no:
Txheej txheej photoresist: Siv ib txheej ntawm cov khoom siv photosensitive sib npaug ntawm qhov chaw ntawm lub substrate kom ntseeg tau tias cov txheej txheej tuab tuab rau qhov tshwm sim tom ntej.
Raug: Cov qauv tsim hluav taws xob tau npaj rau hauv lub substrate coated nrog cov khoom siv photosensitive los ntawm high-precision raug cov cuab yeej, ua rau muaj tshuaj lom neeg tshwm sim nyob rau hauv tej qhov chaw ntawm cov khoom photosensitive.
Kev loj hlob: Lub substrate raug immersed los yog sprayed nyob rau hauv ib tug tsim tawm kom tshem tawm cov unexposed photosensitive cov ntaub ntawv thiab nthuav tawm cov nto ntawm lub substrate los tsim ib tug Circuit Court qauv.
Ntxuav thiab ziab: Tom qab kev txhim kho tiav, ntxuav kom tshem tawm cov khoom seem, thiab tom qab ntawd qhuav los npaj rau cov txheej txheem etching tom ntej.

︉ 、 Qhov tseem ceeb ntawm txoj kev txhim kho
Qhov tseem ceeb ntawm txoj kev txhim kho hauv PCB Circuit Board ntau lawm yog qhov tseem ceeb hauv cov hauv qab no:
Qauv raug: Cov txheej txheem kev txhim kho ncaj qha cuam tshuam cov ntsiab lus thiab qhov tseeb ntawm cov qauv hauv Circuit Court. Cov txheej txheem kev loj hlob zoo tuaj yeem ua kom qhov tseeb ntawm cov kab zoo thiab qhov sib txawv, yog li txhim kho tag nrho cov kev ua tau zoo ntawm lub rooj tsav xwm Circuit Court.
Kev txhim kho cov txiaj ntsig: Los ntawm kev tswj hwm lub sijhawm txhim kho thiab kev tsim kho kom zoo, tus nqi tsis zoo tuaj yeem txo qis thiab cov txiaj ntsig tau nce ntxiv, uas yog qhov tseem ceeb rau PCB Circuit Board board manufacturers.
Txhim kho kev ntseeg tau zoo: Kev txhim kho raug tsis yog tsuas yog txiav txim siab ua haujlwm ntawm lub rooj tsav xwm hauv Circuit Court, tab sis kuj tseem pab txhim kho kev ntseeg tau ntawm tag nrho cov khoom, tshwj xeeb tshaj yog cov khoom siv hluav taws xob uas ua haujlwm nyob rau hauv high-frequency thiab high-temperature ib puag ncig.

四 、 Yam cuam tshuam rau qhov zoo ntawm txoj kev txhim kho
Hauv kev xyaum, ntau yam cuam tshuam rau qhov zoo ntawm txoj kev txhim kho, suav nrog:
Kev xaiv cov ntaub ntawv photosensitive: ntau hom ntawm cov ntaub ntawv photosensitive muaj cov yam ntxwv ntawm kev txhim kho, PCB Circuit Board tuam ntxhab yuav tsum xaiv cov khoom tsim nyog raws li cov khoom xav tau.
Qhov tseeb ntawm cov khoom raug: high-precision raug cov cuab yeej yog ib qho tseem ceeb ua ntej kom ntseeg tau tias kev txhim kho cov txiaj ntsig, thiab kev laus lossis kev ntsuas tsis raug ntawm cov cuab yeej yuav cuam tshuam ncaj qha rau kev loj hlob zoo.
Kev loj hlob tej yam kev mob: lub concentration, kub thiab kev loj hlob lub sij hawm ntawm tus tsim tawm yuav cuam tshuam rau txoj kev loj hlob nyhuv, thiab cov chaw tsim tshuaj paus yuav tsum tau kho raws li qhov tseeb.

Cov txheej txheem kev loj hlob yog ib qho ntawm cov txheej txheem tseem ceeb ntawm PCB Circuit Board board manufacturers, thiab nws qhov zoo yog ncaj qha ntsig txog kev ua tau zoo ntawm cov khoom thiab kev ua lag luam kev sib tw. Los ntawm kev nruam kev thev naus laus zis thiab kev txhim kho cov txheej txheem, PCB cov tuam txhab yuav txuas ntxiv tsim cov txiaj ntsig zoo hauv kev tsim khoom siv hluav taws xob kom tau raws li cov kev xav tau ntawm kev lag luam.
