PCB pawg thawj coj saib hluav taws xob pinch kub thiab npib tsib xee dab dej kub sib txawv?

PCB pawg thawj coj kub tau txais los ntawm electrolysis, thiab kub tau txais los ntawm kev txo cov tshuaj tiv thaiv!

Dab tsi yog qhov sib txawv ntawm PCB hluav taws xob kub thiab sunk npib tsib xee kub.

Txhawm rau muab nws yooj yim, PCB electroplating kub, zoo li lwm yam PCB electroplating, xav tau hluav taws xob thiab kho hluav taws xob. Muaj ntau yam ntawm nws cov txheej txheem, suav nrog cyanide, tsis-cyanide system, tsis-cyanide system thiab citric acid, sulfite thiab lwm yam. Siv hauv kev lag luam PCB tsis yog cov tshuab cyanide.

Kub-plating (tshuaj kub-plating) tsis xav tau hluav taws xob, tab sis tso nyiaj kub rau saum npoo los ntawm kev tshuaj lom tshuaj hauv kev daws teeb meem.

Lawv muaj lawv tus kheej qhov zoo thiab qhov tsis zoo. Ntxiv rau seb nws puas tau siv lossis tsis ua, PCB pawg thawj coj saib kub tuaj yeem ua tuab heev. Ntev npaum li lub sijhawm txuas ntxiv, nws tsim nyog rau kev ua cov laug cam. Txoj hauv kev pov tseg ntawm PCB cov kua electrogold me dua li cov kub. Txawm li cas los xij, PCB cov txheej txheem xav tau kev tswj hwm tag nrho pawg thawj coj, thiab tsis tsim nyog los ua cov kab tshwj xeeb.

Cov ntxhia kub yog feem ntau nyias heev (tsawg dua 0.2 micron) thiab qhov huv ntawm kub yog qhov qis. Cov kua dej ua haujlwm tsuas tuaj yeem muab pov tseg rau qee yam.

Ib qho yog PCB plating los ua npib tsib xee kub

Ib qho yog siv sodium hypophosphite tus kheej REDOX cov tshuaj tiv thaiv los ua txheej txheej npib tsib xee, kev siv cov tshuaj tiv thaiv hloov pauv los ua txheej txheej kub (kamura (TSB71 yog nrog nws tus kheej txo kub), yog tshuaj lom neeg.

Ivy: Ntxiv rau qhov sib txawv hauv txheej txheem ntawm PCB electroplating thiab plating, muaj qhov sib txawv hauv qab no:

PCB electroplated kub txheej yog tuab, siab tawv, yog li nws feem ntau yog siv rau nquag ntsaws ntu ntu, xws li hloov daim npav kub ntiv tes, thiab lwm yam.

Nws kuj tseem siv rau cov hlau tsis muaj vuam vim yog qhov du ntawm lub ncoo.
