Muab piv nrog lub pob tooj liab,titanium anodemuaj incomparable zoo vim hais tias nws belongs rau tag nrho txawv anode hom. Raws li qhov tshwm sim, nws cov txiaj ntsig tau tshwm sim hauv cov ntsiab lus hauv qab no.
i. Stable electroplating uniformity
Qhov zoo ntawm electroplating uniformity ntawmtitanium anodehais txog tias kev siv cov insoluble anode tuaj yeem ua kom ruaj khov electroplating uniformity rau lub sijhawm ntev, uas yog txiav txim los ntawm cov yam ntxwv ntawm insoluble anode. Nyob rau hauv cov txheej txheem ntawm electroplating, thiaj li yuav ua kom lub stability ntawm electroplating uniformity, nws yog tsim nyog los xyuas kom meej tias cov electroplating tej yam kev mob yog tswj thiab ruaj khov. Lub ntsiab lus tseem ceeb heev yog kom tswj tau qhov sib xws ntawm kev tawm ntawm qhov zoo mus rau qhov tsis zoo. Kev ruaj ntseg ntawm kev tso tawm los ntawm qhov zoo mus rau qhov tsis zoo yog qhov loj heev txiav txim siab los ntawm qhov sib txheeb loj ntawm ob.
Nyob rau hauv cov txheej txheem PCB tooj liab plating, lub pob tooj liab soluble siv yuav yaj nrog kev nce qib ntawm electroplating, uas ua rau txo qis anode loj (feem ntau anode qhov siab) thiab qhov kev hloov ntawm thaj chaw txheeb ze. Lub uniformity ntawm tooj liab anode tsis tuaj yeem khaws cia rau lub sijhawm ntev. Lub insoluble anode kuj hu ua" qhov loj ruaj khov anode", uas txhais tau hais tias qhov loj anode ntawm insoluble anode tseem ruaj khov rau lub neej ntev.
Nyob rau lub sijhawm no, nws tsuas yog tsim nyog los xyuas kom meej tias cov txheej txheem ntawm qhov chawtitanium anodetsis poob thaum lub sij hawm kev pab cuam lub neej, thiab tseem muaj peev xwm ntawm paug thiab electrocatalysis, thiaj li ua kom cov paug stability ntawm anode mus cathode. Feem ntau, tom qab lub insoluble anode raug ntsia rau ntawm kab, nws tsuas yog yuav tsum tau kho cov electroplating uniformity thawj zaug (xws li kho qhov loj thiab txoj hauj lwm ntawm lub shielding phaj), thiab ib tug ruaj khov electroplating thickness faib tau rau ib tug. ntev, uas tuaj yeem ua tiav" ib zaug thiab rau tag nrho" nyob rau hauv tag nrho anode lub neej voj voog.
ii. Kev tsim khoom siab dua
Piv nrog rau lub pob tooj liab, kev txhim kho ntawm kev tsim khoom tau coj los ntawmtitanium anodeFeem ntau yog tshwm sim hauv ob yam hauv qab no:
Ntawm ib sab, titanium electrode tuaj yeem ua haujlwm ntawm qhov ceev dua tam sim no. Vim tias qhov kev ua haujlwm ntawm phosphate zaj duab xis nyob rau saum npoo ntawm lub pob tooj liab, qhov siab tshaj plaws ua haujlwm tam sim no yuav tsum tsis pub tshaj 2.5 ~ 3 ASD; Qhov siab tshaj plaws tam sim no uas titanium electrode tuaj yeem tiv taus yog kaum ob lub sij hawm siab dua li ntawm cov pob tooj liab (piv txwv li, hauv cov hlau electroplating, qhov ua haujlwm tam sim no ntawm titanium electrode tuaj yeem ncav cuag ntau dua 100 ASD). Yog li, los ntawm kev txhawb nqa ntawm cov cuab yeej siv thiab kev sib txuam ntawm cov khoom siv electroplating, cov anode muaj peev xwm ua tiav cov cuab yeej muaj peev xwm ntau dua thiab kev ua haujlwm ntau lawm.
Ntawm qhov tod tes, titanium anode zam kev cuam tshuam ntau lawm los ntawm kev sib ntxiv thiab kev saib xyuas ntawm cov txheej txheem pob tooj liab. Thaum siv nws, cov khoom siv tooj liab yuav tsum tau muab ntxiv rau lub sijhawm tsis tu ncua. Ua ntej ntxiv ib lub pob tooj liab tshiab, nws yuav tsum tau ntxuav. Nws tsis tuaj yeem tsim tam sim tom qab ntxiv. Nws xav tau qee lub sijhawm ntawm electrolytic rub lub tog raj kheej ua haujlwm los tsim cov phosphating zaj duab xis ntawm nws qhov chaw. Lub pob tooj liab siv tau ntev yog nyob ze rau lub xeev seem, yog li nws yuav tsum tau muab tshem tawm tag nrho ntawm lub pob tawb titanium kom tsis txhob muaj teeb meem ntawm electroplating zoo.
Cov kev ua haujlwm tsis tu ncua no ua rau cov khoom siv tooj liab plating siv cov pob tooj liab tsis tsuas yog tsis tuaj yeem ua haujlwm tsis tu ncua rau lub sijhawm ntev, tab sis kuj siv ntau lub zog. Cov tooj liab oxide hmoov ntxiv cov cuab yeej sivtitanium anodetxhawm rau ntxiv tooj liab ion yog ywj siab, tsis tas yuav kaw kom ntxiv tooj liab oxide hmoov. Nyob rau tib lub sijhawm, nws yog" kev tu tsis pub", uas yog, hauv paus ntsiab lus, tsis tas yuav tsum ntxuav thaum lub sijhawm nws lub neej. Yog li ntawd, kev siv tuaj yeem ua tiav qhov kev tsim khoom tsis muaj kev cuam tshuam, yog li txuag ntau lub sijhawm txij nkawm thiab peev nyiaj txiag.
