Analysis of unqualified nickel plating layer available plating method?
发布时间：2016/7/11 16:45:48 | 信息来源：Huizhou jia will electroplating technology co., LTDAs said in the vacuum plating or traditional hardware electroplating waste water processing in nickel plating production process. When the nickel layer thickness is not enough, or have no local plating nickel defects when, usable fill plating method.
The workpiece is processed in the following solution:
Added dosage of sulfuric acid
750g/L
Dosage of glycerol
60g/L
The dosage of chromic anhydride
50g/L
Added dosage of oxalic acid
L0g/L
Control range of temperature in electroplating process
L5 ~ 25
DA specific parameters
0.8 ~ 1.2A/dm2
Grasp the time in electroplating process
4 ~ 7S
Via the solution processed parts immediately in 1:3 hydrochloric acid leaching L ~ 3S. This is mainly to wash away the attached on the workpiece of chromic acid, water washing, quickly placed in cyanide copper plating bath copper.
DK specific parameters
0.1 ~ O.2A/dm2
Time accuracy
5 ~ lOmin
Vacuum plating copper after the workpiece and then washed, and dipped 30-50g/L dilute sulfuric acid, washed immediately after the nickel plating bath, according to the original process conditions of nickel plating. The plating time can be determined according to the required thickness.
