Flow of Process :
Soak Cleaner (ALKAN-83LG) --> W/R --> (cathodic)Electro cleaner (ED-63LG) --> W/R --> Acid Pickling --> W/R --> (anodic)Electro cleaner (ED-63LG) --> W/R --> electroplating --> W/R --> Passivation (TC-BL130) --> W/R --> Drying
Note for Electrocleaning step :
The last step of the cleaning cycle should be anodic cleaning and the time of anodic cleaning should be equal to or longer than the time of cathodic cleaning, if any.
