      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.

      Aluminium underlay material is a thin sheet of aluminum. 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, and bird nesting.

      Benefits of Aluminium sheet is that it is:


      • Non Abrasive
      • Cools the Drill Bit
      • Reduces Contamination
      • High Dielectric Strength
      • High Mechanical Strength
      • Dimensional Stability
      • Light Weight
      • Water Resistant
      • Heat Resistant
      • Corrosion Resistant
      • Chemical Resistant
