Cu plating txheej txheem

Cov txheej txheem Cu plating ntawm cov ntawv luam tawm Circuit Board yog ib qho ntawm cov txheej txheem tseem ceeb hauv kev tsim hluav taws xob boards. Cu plating txheej txheem ntawm Circuit Court boards feem ntau yog txheej txheej ntawm hlau zaj duab xis rau saum npoo ntawm lub rooj tsavxwm los tsim cov kev sib txuas hauv Circuit Court thiab teeb liab.

Raws li cov khoom tseem ceeb hauv kev lag luam hluav taws xob, kev ua haujlwm hluav taws xob thiab kev ntseeg siab ntawm cov ntawv luam tawm Circuit Board ncaj qha cuam tshuam rau kev ua tau zoo thiab ruaj khov ntawm tag nrho cov khoom siv hluav taws xob. Ntawm lawv, cov txheej txheem electroplating yog qhov tseem ceeb tshaj plaws ntawm cov txheej txheem tsim hluav taws xob hluav taws xob.

1. Kev kho mob ua ntej

Kev kho mob ua ntej electroplating ntawm cov ntawv luam tawm Circuit Board yog ib kauj ruam tseem ceeb heev, uas tuaj yeem tshem tawm cov impurities thiab cov pa phem tawm ntawm qhov chaw ntawm lub rooj tsavxwm luam tawm, kom ntseeg tau tias cov txheej txheem electroplating tau txais tom qab electroplating tuaj yeem ua raws li qhov chaw ntawm lub rooj tsavxwm thiab muaj txaus. adhesion. Electroplating ua ntej kev kho mob feem ntau suav nrog cov kauj ruam hauv qab no:

ib. Degreasing: Ntxuav saum npoo ntawm lub rooj tsav xwm luam tawm nrog cov tshuaj degreaser los yog cov dej txias kom tshem cov roj thiab cov av ntawm qhov chaw.

b. Decontamination: Soak thiab ntxuav qhov chaw ntawm lub rooj tsav xwm hauv Circuit Court nrog alkaline lossis acidic ntxuav cov neeg ua haujlwm kom tshem tawm cov oxide txheej thiab oxide txheej ntawm qhov chaw thiab tiv thaiv qhov tsis zoo thaum lub sij hawm electroplating.

c. Copper tshem tawm oxidation: Kho cov tooj liab nto nrog kev daws ntawm immersed tooj liab tshem tawm oxidant kom tshem tawm cov oxide txheej thiab cov pa phem.

2.Kev npaj cov tshuaj electroplating

Electroplating kua yog ib feem tseem ceeb ntawm cov txheej txheem electroplating, uas txiav txim siab lub thickness, adhesion, thiab corrosion kuj ntawm electroplating txheej. Cov qauv ntawm cov tshuaj electroplating sib txawv rau cov khoom sib txawv thiab kev tsim kho. Thaum lub sij hawm npaj cov txheej txheem ntawm cov tshuaj electroplating, cov ntsiab lus hauv qab no yuav tsum tau muab sau tseg:

ib. Xaiv cov khoom siv electroplating uas tsim nyog, xws li acid lossis alkali.

b. Txiav txim siab cov txheej txheem ntawm cov tshuaj electroplating, xws li voltage, tam sim no ceev, thiab lub sij hawm electroplating.

c. Xaiv qhov tsim nyog electroplating da dej thiab electrodes.

3.Cu plating ua haujlwm

Kev lag luam electroplating ntawm cov ntawv luam tawm Circuit Board yog qhov tseem ceeb tshaj plaws ntawm tag nrho cov txheej txheem electroplating, uas ncaj qha cuam tshuam rau qhov kawg plating txheej thickness, smoothness, thiab adhesion. Kev ua haujlwm electroplating suav nrog cov kauj ruam hauv qab no:

ib. Xyuas seb lub tank electroplating thiab electrodes puas huv thiab ua tau raws li cov txheej txheem yuav tsum tau ua.

b. Muab lub rooj tsav xwm luam tawm hauv lub da dej electroplating thiab txuas cov electrodes zoo thiab tsis zoo.

c. Tswj lub thickness thiab uniformity ntawm electroplating txheej los ntawm kev kho cov tsis xws li voltage, tam sim no ceev, thiab electroplating lub sij hawm nyob rau hauv cov tshuaj electroplating.

d. Thaum lub sij hawm electroplating txheej txheem, nws yog ib qhov tsim nyog los xyuas qhov kub thiab pH tus nqi ntawm cov tshuaj electroplating kom tsis txhob muaj kev hloov pauv hauv cov tshuaj plating.

e. Tom qab cov electroplating tiav lawm, tshem tawm cov ntawv luam tawm ntawm lub tank electroplating thiab ua cov kev kho mob tom ntej xws li ntxuav thiab ziab kom ntseeg tau tias cov txheej txheej electroplating tuaj yeem ua tau zoo rau saum npoo ntawm cov ntawv luam tawm Circuit Board.

Raws li cov txheej txheem tseem ceeb hauv cov txheej txheem tsim khoom ntawm cov laug cam, Sihui Fuji tau mob siab rau tag nrho nws cov kev siv zog los txhim kho qhov zoo ntawm Cu plating cov khoom thiab tshawb nrhiav ntau txoj hauv kev rau kev txo nqi. Peb siv zog los muab cov neeg siv khoom nrog cov khoom zoo thiab nqi-zoo luam ntawv Circuit Court boards.
