Factors which help control the cu plating thickness would include:
1. A balanced outerlayer image. Add thieving if neecessary, avoid isolated
features which can over-plate.
2. Proper racking of the panels when plating. Make sure that each individual
panel is clamped to the plating racks with good metal to metal contacts.
3. Be consistent when locating the panels in your plating tanks. Meaning the
location of cu anodes in respect to the actual panels should be
equa-distant.
4. good solutuion movement in the cu plating tanks.
These factors along with your typical process controls should help you.
thanks,
