Ib txoj kev xaiv Electroless Thick Kub Plating

Hom phiaj

Txhawm rau tsim cov txheej txheem xaiv electroless tuab kub plating thiab ua ntau yam txheej txheem kho deg

 

Lub hom phiaj

Cov thickness xaiv kub yog siab tshaj {{0}}.3um, thiab cov tsis xaiv kub thickness yog siab tshaj 0.1um

 

Teeb meem

① Cov tshuaj kub tso tawm ntawm cov tshuaj tiv thaiv hloov chaw, nrog kub tuab ntawm 0.03-0.05 micron, tsuas yog tsim rau vuam nto.

②Thaum lub npoo ntawm npib tsib xee maj mam npog los ntawm txheej kub, qhov tso nyiaj qis qis, thiab cov tuab kub yog qhov nyuaj rau ntau dua 0.3 micron thiab ntom.

③Electroplating yuav tsum tau ua ntxiv, uas tsis yooj yim rau ntxiv thaum cov tes hauj lwm sib cuam tshuam

 

Txoj Cai

① Cov txheej npib tsib xee yog siv los txo cov catalytic. Lub hydrogen atom yog adsorbed kom tau txais electrons. Lub atomic hydrogen yog muab los ntawm tus reductant. Lub atomic hydrogen poob electrons thiab nkag mus rau hauv cov tshuaj los ua hydrogen ions.

②Cov thawj xaim ntawm lub rooj tsav xwm Circuit Court thiab cov hlau txheej ntawm tib lub hnab ntim khoom ua si lub luag haujlwm ntawm kev ua cov khoom siv hluav taws xob. Kub ions tau electrons tsis tu ncua ntawm qhov kub thiab tso nyiaj, uas yog sib npaug rau electrogilding

 

Txoj kev thiab kauj ruam

Kauj Ruam 1: Ua cov khoom siv tshuaj hloov pauv kub plating, daim duab yog 10000 zaug SEM duab ntawm kub nto, thiab kub thickness yog<0.02um

Lub hom phiaj: Tshaj tawm cov nickel txheej kom tau txais cov hluav taws xob txo qis

 

Kauj Ruam 2: Muab tshuaj txhuam los tiv thaiv zaj duab xis kom nthuav tawm cov ntaub ntawv sib txuas kom plated nrog kub kub

 

Kauj Ruam 3: Ua tiav thawj qhov txo qis electroless kub plating

Daim duab yog 10000 npaug kub SEM duab

 

 

Kauj ruam 4: Tshem tawm cov yeeb yaj kiab los tiv thaiv

 

Kauj Ruam 5: Tshem tawm electroless kub plating dua

Daim duab yog 10000 npaug kub SEM duab

 

 

 

Cov txiaj ntsig

 

Kub thickness ntsuas tau	Thawj hloov ntawm cov tshuaj nyias nyias	Thawj txo plating ntawm cov tshuaj tuab kub	Thib ob chemical txo plating ntawm tuab kub
Xaiv cov tshuaj tuab kub txoj hauj lwm	0.009-0.014μm	0.293-0.349μm	0.326-0.385μm
Lwm qhov chaw	0.009-0.014μm	Npog nrog anti txheej zaj duab xis	0.105-0.111μm

 

Xaus

Txoj kev xaiv electroless kub plating tuaj yeem ua tau raws li lub hom phiaj.
