Nyob rau PCB, Nickel yog siv los ua cov txheej txheem txheej txheej rau cov khoom muaj nqis thiab cov hlau ua haujlwm. PCB cov kev ntxhov siab tsawg yog plated nrog hloov kho kab ke thiab qee cov sulefamate plating cov kev daws teeb meem uas txo kev ntxhov siab. Cia cov kws ua haujlwm tshaj lij tshuaj xyuas rau koj cov teeb meem twg PCB Nickel plating daws teeb meem feem ntau ntsib thaum siv nws?

1. Npib Txheej Txheem. Nrog kub, da dej kub siv kuj txawv. Nyob rau hauv lub npib tsib xee plating nrog kub siab dua, cov npib tsib xee plating txheej tau muaj qhov kev ntxhov siab tsawg thiab ua kom zoo. Cov kev khiav hauj lwm dav dav yog tswj hwm ntawm 55 ~ 60 degrees. Yog tias qhov ntsuas kub siab dhau lawm, npib tsib xee qab ntsev, ua rau cov pinholes hauv txheej thiab tib lub sijhawm txo cov Catarization Polarization.

2. PH tus nqi. Tus lej pH ntawm npib npib tsib xee-plated electrolyte muaj ib qho kev cuam tshuam zoo rau txheej txheej thiab kev ua tau zoo electrolyte. Feem ntau, tus nqi PHIC ntawm Nickel plating electrolyte ntawm pcb yog tswj hwm ntawm 3 thiab 4. Nickel plating tov nrog siab dua li kev xa khoom ntau dua thiab cathode kev ua tau zoo dua. Tab sis cov pH yog siab dhau, vim hais tias lub Cathode tsis txuas ntxiv ntawm cov txheej txheem hluav taws xob, thaum nws muaj ntau dua 6, nws yuav ua rau pinholes hauv txheej plating txheej. Nickel plating tov nrog qis dua p muaj qhov zoo tshaj plaws anode anode anode anode anode anode anode anode anode ode qhov kawg thiab tuaj yeem nce cov ntsiab lus ntawm cov ntsev hauv cov electrolyte. Txawm li cas los xij, yog tias qhov tsawg tsawg dhau, qhov ntsuas kub tau ntau rau tau txais txheej ci ci ntsa iab yuav nqaim. Ntxiv Nickel carbonate lossis yooj yim Nickel carbonate nce tus nqi PHC; Ntxiv cov sulfamic acid los yog cov sulfuric acid txo qis tus nqi PHQU, thiab cov tshev thiab kho tus lej pH txhua plaub teev thaum ua haujlwm.

3. Anode. Cov tshuaj tsib xhel ntawm cov lej uas tuaj yeem pom ntawm tam sim no txhua qhov siv soluble anodes, thiab nws yog ib qho uas siv titanium ua si li anodes rau sab hauv Nickel Angle. Cov pob tawb titanium yuav tsum muab tso rau hauv ib lub hnab anode ploding ntawm polypropylene khoom los ntawm kev poob rau hauv cov kev ua tiav plating, thiab kuaj seb lub Eyelet yog tus mob.

4. Kev ua kom huv. Thaum muaj cov organic paug nyob rau hauv cov kev daws teeb meem, nws yuav tsum tau kho nrog cov carbon ua haujlwm. Tab sis cov qauv no feem ntau yog tshem tawm ib feem ntawm kev ntxhov siab-relieving tus neeg sawv cev (addutive), uas yuav tsum tau muab tso ntxiv.

5. Kev Ntsuam Xyuas. Cov kev cog haum yuav tsum tau siv cov ntsiab lus tseem ceeb ntawm cov txheej txheem txheej txheem teev hauv cov txheej txheem tswj. Qee lub sijhawm txheeb xyuas cov ntawv sib xyaw thiab kev coj cov chaw ua haujlwm ntawm tes, thiab coj cov chaw tsim khoom ntawm cov tsis sib haum raws li cov khoom tsis muaj.

6. Stirring. Lub Nickel plating txheej txheem yog tib yam li lwm cov txheej txheem electroplating. Lub hom phiaj ntawm kev nplawm yog kom nrawm dua cov txheej txheem hloov pauv ntau ntxiv los txo cov kev hloov pauv ntau dua thiab nce cov nyiaj sab saud. Kuj tseem muaj qhov cuam tshuam tseem ceeb heev ntawm kev sib xyaw ua ke, uas yog kom txo lossis tiv thaiv pinholes hauv npib tsib xee plating txheej. Feem ntau siv cov huab cua compressed, cathode kev txav thiab yuam kev ncig (ua ke nrog carbon core thiab cov paj rwb tseem ceeb) nplawm.

7. Cathode tam sim no ceev. Cathode tam sim no ceev tau muaj txiaj ntsig ntawm Cathode tam sim no efficiency, tso nyiaj tus nqi thiab txheej zoo. Thaum siv cov electrolyte nrog rau Nickel plating, nyob rau hauv thaj chaw qis tam sim no, lub Cathode tam sim no nce nrog kev ua kom ceev tam sim no; Hauv qhov chaw siab tam sim no ceev, cov Cathode tam sim no yog ywj siab yog kev ywj pheej ntawm qhov ceev tam sim no; Thaum thaum siv cov kua hluav taws xob siab dua thaum cov khoom siv hluav taws xob uas muaj hluav taws xob uas muaj hnub nyoog uas muaj hluav taws xob, kev sib raug zoo ntawm cov kev ua tau zoo tam sim no thiab ceev tam sim no tsis tseem ceeb. Ib yam li nrog lwm hom kev plating, qhov ntau ntawm cov Cathode tam sim no xaiv rau Nickel plating yuav tsum tseem nyob ntawm cov kev sib xyaw, ntsuas kub thiab txhaws cov kev daws teeb meem.
