Titanium anode ntxaij rau PCB kab rov tav tooj liab plating
1.Coating type: Titanium-based iridium-tantalum
2.Superiority sib piv nrog cov pa hluav taws xob anodes rau electroplating
1) Lub xovtooj hluav taws xob tsawg thiab lub zog siv tsawg
2) Tsawg hluav taws xob tsis txaus hluav taws xob thiab ruaj khov me me
3) zoo corrosion tsis kam thiab insolubility ntawm lub electrode nws tsis ua paug ntawm cov kua dej da dej thiab ua rau cov kev ua tau zoo ntawm cov xim muaj kev ntseeg zoo dua.
4) Titanium anode txais yuav cov ntaub ntawv tshiab thiab kev teeb tsa, uas txo nws txoj kev hnyav thiab nws yooj yim rau kev ua haujlwm txhua hnub.
5) Kev pab lub neej ntev, thiab lub matrix tuaj yeem rov siv dua, txuag nqi.
6) Oxygen evolution overpotential yog li 0.5V qis dua li ntawm cov txhuas lead insoluble anode.Rau lub xov tooj ntawm tes hluav taws xob thiab txo kev siv zog.
3.Txhua kev ua haujlwm zoo thiab kuaj lub neej
| Npe | Ntxiv dag zog rau kev hnyav hnyav tsis txaus mg | Polarizability mv | Oxygen evolution / chlorine muaj peev xwm v | Kuaj Rau Cov Neeg Mob |
| Titanium-based iridium tantalum | ≤10 | & lt; 40 | & lt; 1.45 | 1mol / L H2SO4 |
4.Cov khoom lag luam rau PCB Copper Plating
Acidc elecrolytic tooj liab plating yog qhov txuas tseem ceeb hauv cov txheej txheem metallization ntawm cov ntawv luam tawm Circuit Court qhov. luam tawm Circuit board kev lag luam tsim kho sai sai ntawm kev coj ntawm multilayer, txheej txheej, kev ua haujlwm thiab kev sib koom ua ke Cov ntawv luam tawm Circuit Court tsim kom muaj ntau qhov ntawm cov qhov me me, nqaim, thiab nyias cov xov hlau rau lub tswv yim thiab tsim ntawm Circuit Court pattems, uas ua rau kev tsim kho tshuab thev naus laus zis ntawm cov ntawv luam tawm Circuit Court nyuaj ntau dua, tshwj xeeb tshaj yog cov nam piv ntawm ntau txheej txheej los ntawm qhov ntau tshaj 5: 1 thiab cov khoom siv Lub qhov loj loj ntawm qhov sib sib zog nqus dig muag qhov siv nyob rau hauv lub laminate ua rau cov pa hluav taws xob ua tiav cov txheej txheem tsis tuaj yeem ua kom tau raws li cov kev cai rau siab -Qhov zoo thiab muaj kev ntseeg siab ntawm qhov sib txig sib dhos, yog li lub tshuab hluav taws xob kab rov tav yog tsim.
1.PCB kab rov tav rov qab pulse tooj liab plating.
Vim tias cov qauv tsim ntawm Circuit Board feem ntau yuav tsum yog nyias lub xov kab, muaj kev kub ceev, zoo aperture (siab pom qhov sib piv, txawm tias micro-ntawm, thiab sau cov qhov muag tsis pom kev, cov tsoos DC elcroplating ua ntau dua thiab tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, tshwj xeeb plating txheej hauv nruab nrab ntawm qhov aperture ntawm lub qhov-los ntawm plating, feem ntau yog koom tes txheej ntawm ob qho kawg ntawm aperture yog xav dhau lawm tab sis qhov nruab nrab tooj liab txheej tsis zoo.Qhov tsis ncaj ntawm txheej yuav cuam tshuam rau qhov cuam tshuam ntawm kev sib kis tam sim no thiab ncaj qha ua rau cov khoom lag luam tsis zoo. Txhawm rau ntsuas qhov tuab ntawm tooj liab nyob rau saum npoo, tshwj xeeb tshaj yog nyob rau hauv lub qhov thiab micro-hols, nws raug yuam kom txo qhov ntom ntom tam sim no, tab sis qhov no yuav txuas lub platng lub sijhawm mus rau theem tsis tsim nyog. kev txhim kho ntawm thim rov qab mem tes electroplating txheej txheem thiab tshuaj ntxiv rau qhov tsim nyog rau cov txheej txheem elecroplatig, shrortening lub sijhawm platng tau dhau los ua qhov tseeb, thiab cov teeb meem no tuaj yeem kov yeej los ntawm rev erse mem tes electroplating txheej txheem.
Cov txheej txheem raug electrolysis:
Electrolyte: CuSO4 / 5H2O: 100-300g / L, H2SO4: 50-150g / L

2.PCB ntsug nruam DC tooj liab plating
Nyob rau hauv PCB vetical txuas ntxiv DC tooj liab plating txheej txheem, tshwj xeeb cov organic ntxiv rau ntxiv los txhawb cov nplua-xim hlau tso txheej txheej thiab qhov teeb meem sib cais ntawm pawg thawj coj saib. Cov additives no yuav tsum tau tswj hwm ntawm qhov kev pom zoo hauv lub siab thiaj li ua tiav lawv txoj haujlwm zoo thiab tau txais cov khoom lag luam zoo tshaj plaws.
Qhov no yuav tsum tau siv lub anode tsis tsuas yog ua tiav lub neej muaj sia, tab sis kuj noj me me li cov organic ntxiv tau kom txo tau tus nqi ntawm kev noj tshuaj txawm hais tias qhov ua kom tsis haum iridium-based titanium anode tuaj yeem ncav cuag qhov yuav tsum tau sevice lub neej, nws noj ib lub ot ntawm brightener. peb tau txhim kho cov txheej txheem thiab cov qauv ntawm tsoos iridium-puag titanium anodes. Qib PCB theem tooj liab-plated titanum anodes uas txo kev noj haus ntawm cov organic ntxiv tuaj yeem ua tiav lub neej kev pabcuam.
Cov txheej txheem raug electrolysis:
Electrolyte: Cu: 60-120g / L, H2SO4: 50-100g / L, Cl-: 40-55ppm
