Masking Techniques
For Area Definition & Part Protection

2. Why We Mask
To prevent plating from being applied where it is not wanted
To exactly define the area that is to be plated
To reduce waste of metal from the plating solution
To prevent chemical damage to adjacent areas of the part
To prevent contamination of the plating solution

3. Considerations Before Masking Consider
The area must be pre-cleaned to ensure that the masking materials will stick
Consider
How a solution will be applied
Anode to cathode movement
Configuration of the part
Duration of the plating operation
Temperature at the work area
