Vim li cas PCB electroplating kub txheej tig dub?

1. Potion xwm txheej ntawm electroplated nickel tank

Tseem yuav tau tham txog lub nickel tank. Yog hais tias lub nickel tank potion tsis zoo khaws cia rau lub sijhawm ntev, thiab kev kho cov pa roj carbon monoxide tsis tau ua tiav raws sijhawm, cov txheej txheem nickel tom qab electroplating yuav yooj yim tsim cov muaju, cov tawv tawv ntawm cov txheej plating yuav nce, thiab brittleness ntawm cov khoom siv. txheej yuav nce. Hauv qhov xwm txheej hnyav, blackening ntawm txheej yuav tshwm sim. Qhov no yog vim muaj coob tus neeg nyiam saib dhau lub ntsiab lus tseem ceeb ntawm kev tswj hwm. Nws kuj yog ib qho tseem ceeb ua rau muaj teeb meem. Yog li ntawd, thov ua tib zoo xyuas cov txheej txheem potion ntawm koj lub Hoobkas cov kab ntau lawm, ua qhov kev soj ntsuam sib piv, thiab ua tib zoo saib xyuas cov pa roj carbon monoxide hauv lub sijhawm kom rov ua haujlwm potion thiab ntxuav cov tshuaj electroplating.

2. Thickness tswj ntawm electroplated npib tsib xee txheej

Txhua leej txhua tus yuav tsum tau tham txog blackening ntawm electroplated kub txheej, yuav ua li cas nws yuav ua tau lub thickness ntawm electroplated npib tsib xee txheej. Qhov tseeb, PCB plating kub txheej yog feem ntau nyias nyias, xav txog tias muaj ntau yam teeb meem ntawm lub plating kub yog tshwm sim los ntawm kev ua haujlwm tsis zoo ntawm electroplating npib tsib xee. Feem ntau, thinning ntawm electroplated npib tsib xee txheej yuav ua rau cov tsos ntawm cov khoom yuav dawb thiab dub. Yog li, qhov no yog thawj qhov kev xaiv rau lub Hoobkas engineers thiab cov kws tshaj lij los xyuas. Feem ntau, lub thickness ntawm cov nickel txheej yuav tsum tau electroplated txog li 5 um kom txaus.

3. Kub lub tog raj kheej tswj

Tam sim no nws los txog rau lub tog raj kheej kub tswj. Feem ntau, ntev li ntev tau koj tswj xyuas qhov zoo potion filtration thiab replenishment, cov pa phem thiab ruaj khov ntawm lub tog raj kheej kub yuav zoo dua li cov nickel cylinder. Tab sis koj yuav tsum tau ua tib zoo saib xyuas seb cov hauv qab no puas zoo:

(1) Puas yog cov tshuaj ntawm lub tog raj kheej golden txaus thiab ntau dhau?

(2) Tus nqi PH ntawm lub potion tswj tau li cas? (3) Yuav ua li cas yog lub conductive ntsev?

Yog tias tsis muaj teeb meem nrog qhov kev tshuaj ntsuam xyuas, siv lub tshuab AA los soj ntsuam cov ntsiab lus impurity hauv cov tshuaj. Guarantee lub potion xwm txheej ntawm lub tank kub. Thaum kawg, tsis txhob hnov ​​​​qab xyuas yog tias lub tog raj kheej golden lim tseem tsis tau hloov lub sijhawm ntev.
