Back up board for PCB drilling process
White Melamine Wood Backup Board is boards of different types of plate. made of urea formaldehyde. or phenolic resin. or other resin and wood fiber board made by different producing process.
Medium and high density fibreboard materials. with or without more surface layers. suitable for use as a back-up material in PCB drilling and routing applications. in various thicknesses and thickness tolerance classes.
Medium Density Fiberboard(MDF) called density fibreboard. As a backup board for pcb drilling, so it also called wood backup board. It made of wood fibers or other plant fibers as raw materials. prepared by fibers, applied synthetic resins, and pressed under heating and pressure.
PCB drilling white melamine Entry and Backup Board is a board. made up of urea formaldehyde or other resin. and phenolic resin or wood fiber board made by different process of different types of plate.

white melamine PCB drilling Entry and Backup Board advantages
PCB drilling white melamine Entry and Backup Board is a kind of new type of drilling cushion for small hole. Then it turn to be compound board with solidity surface and stretchy midst core.
It can
-Reduced drill temperature and drill wear.
-Increased hit counts, reducing cost per hole drilled.
-Increased stack heights.
-Excellent drill cleaning and chip formation.
-Improved hole-wall quality.
-Reduced costs
Due to the clean, flat and hard surface PCB drilling entry boards. and back up board provide accurate drill entry. and even at the highest drill speeds, the drills and the smallest holes are not damaged.
drilled melamine board application
White Melamine wood Backup Board for PCB drilling is a kind of new type of drilling cushion for small hole. Then it turn to be compound board with solidity surface and stretchy midst core. It can used for the hole on precise multilayer circuit board. It’s designed to replace the phenolic backup board in particular. especially for the pinhole aperture, multilayer board. and flexible Board.
it is for:
PCB/ FPCB drilling and routing entry/ backup board.
Minimum diameter for drilling: 0.15(mm)
Minimum diameter for driiling is only for reference.
Different drilling parameters will cause various results.
White melamine laminated fiberboard storage
Temperature: Below 27 degrees Celsius
Humidity: Below 60%
Please place the entry board
Avoid rubbing the entry board against other objects
