Small Hole Deburring in Paper Phenolic Charge Electrodes

This is a technique for removing burrs in phenolic charge electrodes without changing the original size or shape of the hole.

After the holes have been drilled, the phenolic board is coated with electroless copper or nickel, approximately 1 micron in thickness. This accentuates the burrs and makes them brittle. The shank portion of an undersize drill is then fed through each hole, snapping off the burrs and leaving the holes symmetrical in size and shape.
