1.5mm Phenolic reisn Drill Exit Board

  • Composition

    An important drilling consumable is the underlay or backing material.The purpose of the backing material is to prevent exit copper burrs onthe underside of the drilled boards and to provide adequate space fordrill stroke termination. An acceptable backup material does notcontaminate the hole and helps cool the drill bit, thereby improvinghole quality.

    We supply Phenolic sheet as a backing material as it is a hard, densematerial made by applying heat and pressure to layers of paperimpregnated with synthetic resin. When heat and pressure are applied tothe layers, a chemical reaction (polymerization) transforms the layersinto a high-pressure thermosetting industrial laminated plastic.Ideally suited for use as a drill backing material.

  • Description

    Phenolic Drill Exit Board material has tight thickness and flatness tolerances. Itcontain no abrasives that could increase drill wear or contaminatesthat could be evacuated through the drilled hole. The surface is smoothand hard to properly suppress exit burrs
