Insoluble anode txhais
Anodes uas tsis yaj lawv tus kheej thiab tsuas yog raug oxidation cov tshuaj tiv thaiv thaum tam sim no dhau los ntawm cov txheej txheem electroplating yog sib sau ua ke hu ua insoluble anodes.Insoluble anode cov ntaub ntawv hauv electroplating muaj xws li txhuas, carbon, platinum, graphite, nickel, stainless hlau, titanium plated nrog platinum, iridium. -plated tantalum, ruthenium-plated iridium, rhodium, thiab lwm yam.
Cov xwm txheej uas insoluble anodes siv nyob rau hauv Circuit Court board kev lag luam feem ntau muaj xws li electroplating tooj liab, electroplating kub, electroplating nyiaj, thiab ib puag ncig tus phooj ywg kev kho mob ntawm ammonia nitrogen thiab COD, thiab lwm yam.Qhov feem ntau lug siv HDI board tooj liab-plated insoluble iridium thiab tantalum anode rau Circuit Court boards muaj cov kev xav tau siab ntawm kev noj cov khoom siv lub teeb.Qhov kev ruaj ntseg ntawm electroplating lub teeb tus neeg saib xyuas thaum lub sij hawm electroplating txheej txheem muaj ib qho tseem ceeb heev cuam tshuam rau qhov zoo ntawm electroplating.
Cov anode insoluble plays anode conductive luag hauj lwm thaum lub sij hawm tag nrho cov txheej txheem electroplating thiab precipitates oxygen los yog oxidized hlau ions.
Muaj ob yam tseem ceeb ntawm kev siv cov anodes insoluble rau Circuit Court boards ntawm cov kua da dej:
●Oxygen evolution nyob rau saum npoo ntawm thawj anode kuj yuav ua rau poob ntxiv ntawm electroplating brightener.Dab tsi tshwm sim nyob rau saum npoo ntawm anode catalytic txheej yog ib tug ncaj oxidation cov tshuaj tiv thaiv.Lub ntsiab cov tshuaj tiv thaiv yog cov hydroxide nyob rau hauv da dej yog catalyzed los ntawm noble. hlau catalytic txheej thiab poob ib qho hluav taws xob ntawm qhov qis dua los ua oxygen. Nyob rau tib lub sijhawm, cov organic teeb meem hauv chav da dej kuj muaj lub sijhawm los oxidized los ntawm kev tso tawm ntawm lub anode.Qhov tseem ceeb ntawm cov txheej txheem tsim anode yog tswj cov pa oxygen evolution peev xwm, thiab tsis txhob cia cov organic teeb meem nyob rau hauv cov txheej txheem. da dej ua kua kom muaj lub cib fim tso ncaj qha rau ntawm lub anode.Lub sab sauv tawm yog oxidized.
● Qhov thib ob cuam tshuam rau cov ntsiab lus oxygen yaj ntawm cov kua da dej. Cov pa oxygen tsim tawm ntawm qhov chaw anode yuav tsum tau khiav tawm ntawm lub anode thiab khiav tawm ntawm lub da dej kom sai li sai tau kom txo tau nws lub sijhawm nyob hauv da dej.(Cov tshuaj tiv thaiv mechanism ntawm mem tes hlau-muaj ions txawv thiab cov pa oxygen tsawg heev).
Insoluble anodes muaj qhov zoo hauv qab no tshaj li cov khoom siv tooj liab
Lub anode tam sim no tsis yog txwv thiab tuaj yeem tsoo lub taub hau ceev tam sim no yog yooj yim rau lub zog tooj liab tau yooj yim dua), nce ntau lawm ntau lawm , tshwj xeeb tshaj yog rau FPC cov kab ntau lawm, kev ua haujlwm tas li ntawm RTR tau ua tiav Lub Hoobkas siv cov anodes insoluble.
Thaum lub sij hawm electroplating txheej txheem, lub anode raug oxidation cov tshuaj tiv thaiv kom tau electrons los ntawm hydroxyl radicals los tsim oxygen. Tsis muaj cov av nkos anode, tsuas yog tso pa tawm kom tswj tau cov hlau ion concentration faib hauv cov tshuaj electroplating ntawm qhov chaw ruaj khov.(Tom qab kev daws qhov cuam tshuam ntawm pulse ntawm lub neej anode, nws yuav muaj txiaj ntsig zoo rau cov kab ntau lawm, uas tuaj yeem ua tau zoo heev. txhim kho cov khoom zoo, txo cov nqi tu, thiab nce cov khoom siv tus nqi).
Qhov loj ntawm lub anode yog ruaj khov, thiab thaj chaw anode tsis hloov thaum lub sij hawm electroplating txheej txheem.Qhov kev faib tawm tam sim no tseem tuaj yeem suav tias yog lub xeev tas li, uas yog qhov muaj txiaj ntsig zoo rau kev txhim kho qhov ntom ntom tam sim no, tshwj xeeb tshaj yog rau HDI cov kab zoo. , qhov filling, thiab pulses.
Insoluble anode txheej txheem yuav tsum
Qhov sib txawv ntawm cov anodes insoluble peb feem ntau siv nyob rau hauv Circuit Court board electroplating thiab zoo tib yam insoluble anodes lies nyob rau hauv lub poob ntawm organic teeb meem.Qhov no txawv nyob ntawm seb muaj pes tsawg leeg thiab cov qauv ntawm cov precious hlau txheej, uas yog, txheej catalytic.
Muaj ob yam uas yuav tsum tau ua kom ntseeg tau thaum lub sijhawm tsim khoom.
◆ Ua ntej, xyuas kom muaj kev sib raug zoo heev, uas yog hais txog lub zog sib txuas ntawm cov txheej thiab titanium substrate.
◆ Thib ob, xyuas kom meej qhov hloov pauv ntawm cov hlau muaj txiaj ntsig hauv txheej txheej rau hauv cov khoom siv hluav taws xob zoo.
| Xyuas kom lub zog sib txuas yuav tsum tau |
| 1. Huv qhov chaw |
| 2.Suitable nto roughness |
| 3.Cov qauv siv lead ua ntawm cov txheej txheem catalytic zoo ib yam li cov qauv siv lead ua ntawm cov txheej txheem hauv qab (rutile qauv).Raws li lub hauv paus ntsiab lus ntawm cov miscibility zoo sib xws, tsim cov qauv riveted tuaj yeem txhim kho lub zog sib txuas. |
| Kev hloov pauv tus nqi ntawm txheej txheej precious hlau yuav tsum tau |
| Ua ib qho loj ntawm cov ntaub ntawv ntsuas qhov tseeb ntawm cov qauv thiab cov txheej txheem tsim khoom kom pom cov qauv zoo tshaj plaws thiab cov txheej txheem ntau lawm. |

Titanium anode tsim qauv
Titanium anode yuav tsum tau siv:
Pib los ntawm cov kev xav tau tiag tiag ntawm cov neeg siv, thaum cov txheej txheem tooj liab plating yog hloov los ntawm phosphor tooj liab pob rau titanium anodes, thawj qhov yuav tsum tau ua yog kom ua tau zoo thiab ruaj khov txhim kho qhov sib xws ntawm electroplating, uas yuav ua rau kev txhim kho zoo; Qhov thib ob, qhov zoo. ntawm titanium anode yuav tsum tau ua kom ruaj khov, ua kom tau raws li qhov xav tau kev pab cuam lub neej, thiab ua kom muaj kev ruaj ntseg ntxiv ntawm cov khoom siv nyob rau lub sijhawm no los xyuas kom meej tias cov nqi khiav lag luam tuaj yeem tswj tau. Yog li ntawd, cov ntsiab lus tseem ceeb yog cov hauv qab no:zoo heev plating uniformity,ruaj khov kev pab cuam lub neej, thiab controllable additive noj qib.
Titanium anode paug uniformity tsim:
| Tau ntsib nrog qhov teeb meem tsim ntawm yuav ua li cas txhawm rau txhim kho qhov sib txawv ntawm titanium anodes, peb tuaj yeem xav txog cov hauv qab no. |
| Teeb meem tiv thaiv |
| Lub hom phiaj optimization ntawm anode substrate hom |
| Kev cuam tshuam ntawm npuas ntawm conductive uniformity |
Catalytic Coating Design:
Anode txheej tsim feem ntau yog txiav txim siab los ntawm ob yam: cov ntsiab lus hlau muaj txiaj ntsig thiab txheej txheej tsim qauv.
Rau anodes haum rau PCB cov txheej txheem tooj liab plating, cov ntsiab lus hlau muaj nuj nqis feem ntau yog hais txog cov ntsiab lus ntawm iridium hlau; thaum lub txheej txheej txheej suav nrog kev xaiv cov khoom siv tshwj xeeb rau txheej txheej, kev hloov pauv ntawm txheej txheej, thiab kev hloov pauv hauv kev txiav txim. ntawm txheej daim ntawv thov.Design ntawm ntau yam kev ua thiab raug txuas.
Cov ntsiab lus
Raws li PCB cov khoom yuav tsum tau nce thiab PCB Hoobkas automation txhim kho, titanium anodes yuav maj mam hloov phosphor tooj liab npas nyob rau hauv lub PCB tooj liab plating txheej txheem nrog lawv zoo heev kev kawm. Hloov cov pob tooj liab yog qhov pom tseeb.Tam sim no, qhov tshwm sim ntawm qee cov ntawv thov tshiab kuj tau muab cov kev xav tau tshiab rau kev tsim khoom ntawm titanium anodes.Qhov no yog ob qho tib si lub sijhawm thiab kev sib tw rau kev tsim thiab kev loj hlob ntawm titanium anodes.
Rau cov tuam txhab anode, lawv yuav tsum ua ntej, teb sai sai rau cov kev xav tau ntawm kev lag luam, thiab tso cov khoom zoo meej rau hauv kev ua lag luam. Iridium Technology teb rau cov kev xav tau ntawm cov neeg siv khoom kawg, cov cuab yeej tsim khoom, thiab cov tuam txhab tshuaj, thiab pab txhawb nqa kev pab cuam rau PCB. kev lag luam.
