Product Description
FR4 Epoxy Glass Cloth Laminated Sheet
Description
This laminated product is formed through heat pressing after electric industry alkali glass cloth dips into the epoxy phenolic resin. It has high mechanic and dielectric performance, and applicable as insulation structural components for electromechanical/electrical equipment, as well as used under damp environmental conditions and transformer oil .
Technical requirement for surface
The surface of laminated board should be flat and smooth, no bubble, no wrinkle, no delamination or crackle, and properly free from other defects such as scrape, impress,dirty spot and uneven color, but a little color patches is allowed.The surface of laminated board should be flat and smooth, no bubble, no wrinkle, no delamination or crackle, and properly free from other defects such as scrape, impress, dirty spot and uneven color, but a little color patches is allowed.
