PCB pawg thawj coj saib electroplating yog kom tau txais kub los ntawm electrolysis, thiab tshuaj txo cov tshuaj yog kom tau kub los ntawm tshuaj txo cov tshuaj tiv thaiv. Cias muab, PCB electroplating kub, zoo li lwm yam PCB electroplating, xav tau lub hwj chim thiab lub rectifier. Muaj ntau ntau yam txheej txheem, suav nrog cyanide-muaj, tsis-cyanide systems, thiab tsis-cyanide systems, xws li citric acid hom thiab sulfite hom. Tag nrho cov tshuab tsis-cyanide yog siv hauv kev lag luam PCB.

Tshuaj kub (electroless kub plating) tsis tas yuav energized, nws deposits kub ntawm lub rooj tsavxwm los ntawm ib tug tshuaj tiv thaiv nyob rau hauv cov tshuaj.

Lawv muaj lawv tus kheej qhov zoo thiab qhov tsis zoo. Ntxiv nrog rau kev siv hluav taws xob tab sis tsis siv hluav taws xob, PCB pawg thawj coj tuaj yeem ua kom tuab heev, ntev npaum li lub sijhawm txuas ntxiv, nws tsim nyog rau kev sib koom ua ke. Lub caij nyoog ntawm PCB tsim electro-kub potion raug muab pov tseg yog me dua li cov tshuaj kub. Txawm li cas los xij, PCB hluav taws xob kub yuav tsum tau txuas nrog tag nrho lub rooj tsavxwm, thiab nws tsis haum rau cov kab nyias nyias.

Cov tshuaj kub yog feem ntau nyias nyias (tsawg dua 0.2 microns), thiab cov purity ntawm kub yog tsawg. Cov kua dej ua haujlwm tsuas yog muab pov tseg thaum siv rau qee yam.

Ib qho yog PCB electroplating los ua npib tsib xee kub

Ib qho yog kev siv sodium hypophosphite tus kheej oxidation-txo cov tshuaj tiv thaiv los tsim ib txheej npib tsib xee, thiab hloov cov tshuaj tiv thaiv los ua cov txheej kub (Uemura’s (TSB71 yog nrog tus kheej txo kub)), uas yog ib txoj kev tshuaj.

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

PCB electroplating kub txheej yog tuab thiab nyuaj, yog li nws feem ntau yog siv rau nquag ntsaws thiab ntxig zawv zawg qhov chaw, xws li cov ntiv tes kub ntawm cov ntawv hloov pauv;

Immersion kub yog zoo rau mounting vim lub tiaj tiaj ntawm lub ncoo thiab kuj yog siv rau cov hlau lead-free soldering.
