Drill Entry Board features

As a typlic replacement of Phenolic Drill Entry Board material. constructed of layers of kraft papers impregnated with modified phenolic resin. It is the most economical entry board material.
FEATURES AND BENEFITS of Entry Board - Phenolic
Drill backing Board
Flat surface
Eliminates burr
Eliminates smearing
Resistance to surface marks
Good hole finish
Reduces drill temperature and extends drill life

Characteristics & Applications Fabricating Suitability Minimum Diameter for Drilling (mm)
For BGA drilling entry or back-up use,low percentage of warp and twist No smear or burr occurrence while drilling ≧0.15φ
For PCB drilling entry or back-up use, low percentage of warp and twist No smear or burr occurrence while drilling ≧0.2φ
For BGA drilling entry or back-up use, low percentage of warp and twist No smear or burr occurrence while drilling ≧0.10φ

Phenolic board VS white melamine back up board

PH-BOARD (paper-phenolic drilling boards / back-up boards), made of paper and phenolic resin.
MPH-BOARD (melamine paper-phenolic drilling boards), made from paper and phenolic resin. covered with melamine foil on both sides.
W-BACK UP (wooden back up board), made of compressed wood fibres with a smooth, glossy and hard surface.
MW-BACK UP (melamine wooden back-up board). made from compressed. wood fibres coated both sides with a special white composite foil. which provides material with a smooth, glossy and extra hard surface.
PH Board made up of paper and phenolic resin. The material  used as both as entry and a backing board during drilling process.
Composition MW Back up made of compressed wood fibres coated both sides. with a special white composite foil
In a word, compare to melamine board. Melamine baord is more cost efffective and Environmental protection. Thus, we suggest you buy white melamine entry baord and backup baord for PCB drilling in Yuehsan
