Drilling backing material for 4MILL milling machines

P2J-DUM is a backing plate designed to meet the highest demands in PCB drilling. P2J-DUM is a fibreboard that goes through a high-pressure flat press and remains in a climate-controlled chamber for a period of time. After multiple sanding, the boards are laminated on both sides. P2J-DUM is recommended for drilling and milling of high-tech circuit boards, multilayer boards, etc. Compared to conventional MDF or phenolic boards, it provides a number of features and benefits.


Technical Advantages
- Specially designed for PCB drilling, made from de-resinated softwood fibers without any adhesives
- Excellent flatness and the tightest tolerances
- Flat, dense and very smooth surface coating reduces burrs and tool wear
- Homogeneous, high density core provides excellent chip removal and reduces drill bit breakage
- Suitable for all drill diameters
- For use with single/duplex, multilayer PCBs etc.
- No hole fouling caused by phenolic particles or resin coating
- Consistently high quality due to strict manufacturing tolerances well below DIN limits; manufacturing and quality control to DIN/ISO-9001
- White surface for visual inspection of drilling
