Bakelite/Phenolic board——PCB drilling accessories/FR4/FPC/entry material

1.Usage

         Phenolic resin and wood pulp paper are mixed with and laminated together with other raw fibers materials.

Suitable for fine multilayer PCB/ FPC use.

2.Introduction

       A. The material is uniform and free of impurities. The overall density and hardness are uniform.

B. The chip is uniform and fine, which helps to improve the quality of micro-hole drilling. Suitable for precision FPC, high-end micro-hole drilling.

C. The flatness is good, and the thickness tolerance in the board is relatively small.

        D. low cost with a widely use. 

         E. surface formation, avoid warpage due to climate change
