Selective PlatingSelective Plating

An established

technique which is

• Fast

• Reliable

• Portable

• Environmentally friendly

Technical OverviewTechnical Overview

•• Selective Plating is different than tank platingSelective Plating is different than tank plating

��Brushing action results in disturbance of solution Brushing action results in disturbance of solution
