An important drilling consumable

 


An important drilling consumable is the underlay or backing material. The purpose of the backing material is to prevent exit copper burrs on the underside of the drilled boards and to provide adequate space for drill stroke termination. An acceptable backup material does not contaminate the hole and helps cool the drill bit, thereby improving hole quality.

Typical materials include aluminum-clad wood core composites, melamine-clad wood core composites, solid phenolics, and paper-resin hard board.

Phenolic sheet is a hard, dense material made by applying heat and pressure to layers of paper impregnated with synthetic resin. When heat and pressure are applied to the layers, a chemical reaction (polymerization) transforms the layers into a high-pressure thermosetting industrial laminated plastic. Ideally suited for use as a drill backing material.

Phenolic sheet material has tight thickness and flatness tolerances. It contain no abrasives that could increase drill wear or contaminates that could be evacuated through the drilled hole. The surface is smooth and hard to properly suppress exit burrs.
