Product Description

Re:Melamine Backup Board (White)

Composition:
Inside material: High-Density Fiber Wood Board
Surface material: The layer of melamine is water-based protection environmental materials. 

Special Features:
It's suitable for using in high-class and multi-layer PCB drilling. Use water-based environmental protection materials, no pollution. The surface is White matt.The unique production process makes the surface with flat and smooth, the plate shape is not easy to warp deformation. Unique additive material have the effect of lower drill temperature, reduce bit wear and increase drilling location accuracy. The board has with low water absorption, long warranty period, better stable quality.
