Dab tsi yog cov yam ntxwv thiab qhov zoo ntawm lub tshuab nqus tsev electroplating hluav taws xob cua sov raj dip tin plating
Nws yog rau raus lub workpiece nyob rau hauv ib tug tov uas muaj cov hlau ntsev yuav tsum tau plated, thiab tso ib tug hlau txheej rau saum npoo ntawm lub workpiece raws li lub hauv paus ntsiab lus ntawm kev hloov tshuaj. Qhov no yog qhov txawv ntawm txoj cai dav dav electroless plating, vim tias tus neeg sawv cev txo qis tsis muaj nyob rau hauv cov tshuaj plating. Nws kuj txawv ntawm kev sib cuag plating. Thaum lub workpiece yog immersed nyob rau hauv cov hlau ntsev tov yuav tsum tau plated, nws yuav tsum tau sib txuas nrog ib tug active hlau. Cov hlau nquag nkag mus rau hauv cov tshuaj rau lub anode tso tawm electrons, thiab cov hlau ions uas muaj peev xwm ntau dua hauv cov tshuaj tau txais electrons. tso rau ntawm lub workpiece nto. Immersion tinning tsuas yog ua rau hlau, tooj liab, txhuas thiab lawv cov alloys.
Lub tshuab nqus tsev electroplating hluav taws xob cua sov raj yuav tsum siv palladium ua ib qho catalyst
(Feem ntau, tus qauv tooj liab yog electroless npib tsib xee plating nrog hypophosphite raws li tus neeg sawv cev txo qis, thiab cov tshuaj tiv thaiv oxidation ntawm tooj liab thiab hypophosphite tsis muaj catalytic activation tus cwj pwm, uas yuav tsum tau palladium ua catalyst. palladium tov, thaum tus qauv tooj liab impregnated nrog catalyst palladium, cov txheej txheem ntawm electroless npib tsib xee plating yuav siv tau.
Txawm li cas los xij, seb txoj kev txheej txheem no puas siv tau rau lub substrate nrog ultra-high density thaiv nyob ntawm qhov kev xaiv ntawm palladium catalyst, vim hais tias thaum lub substrate yog immersed nyob rau hauv cov tshuaj catalytic, cov resin ntawm tus neeg xyuas pib qauv yuav adsorbed tib lub sij hawm. . Nyob rau sab saum toj ntawm cov resin deposited ntawm cov qauv, qhov no tsim teeb meem zoo.
Acid Bright Tin Plating Technology ntawm Nqus Electroplating Hluav Taws Kub Kub Tube Methane Sulfonic Acid System
(1) Muaj tshuaj lom neeg ruaj khov, oxidation tsis kam hauv huab cua, thiab tsis yooj yim rau hloov xim.
(2) Raws li ib txwm muaj, txheej txheej tin-plated yog txheej txheej cathodic rau cov hlau, yog li cov hlau substrate tuaj yeem tiv thaiv tau zoo thaum txheej txheej tsis muaj qhov khoob; tab sis nyob rau hauv ib qho organic acid nruab nrab (xws li hauv ib lub kaus poom) nyob rau hauv airtight tej yam kev mob, tin Nws yog ib tug anodic txheej, uas tseem muaj electrochemical tiv thaiv txawm tias muaj pores, thiab cov yaj tin tsis muaj teeb meem rau tib neeg lub cev, yog li nws yog feem ntau. siv los ua ib txheej tiv thaiv rau cov ntim khoom noj.
(3) Tin muaj qhov zoo conductivity thiab yooj yim rau solder, yog li nws feem ntau siv rau electroplating ntawm cov khoom siv hluav taws xob, cov ntawv luam tawm thiab cov khoom siv hluav taws xob tsawg.
