2.0,2.5MM Melamine coated wood PCB backup board advantage
as some sort of new kind of drilling cushion for small hole. it turn to become compound board with solidity surface area and stretchy midst primary. It can be utilized for the hole on exact multilayer circuit panel.
It's ideal to replace the phenolic backup plank in particular, specifically for the pinhole aperture, multilayer table and flexible Board.
same surface hardness as the phenolic backup board but stabilize dimension and not easy to distort.
it's more environmental friendly bcz it's easy been treated after usage
