What is the material of CEM-1?
CEM-1 belongs to the epoxy glass cloth paper base sheet.
The CEM-1 sheet is formed by a glass fiber-based semi-solidified sheet cover and a wood pulp paper based semi-solid tablet laminated copper foil is formed. Its main material has brominated epoxy resin, solvent, cured accelerator, inorganic filler, glass fiber cloth, wood pulp paper, copper foil, and the like. Its manufacturing process includes wood pulp paper primary glue (water-soluble resin), wood pulp paper secondary upper glue (flame retardant epoxy), glass fiber cloth (flame retardant epoxy resin), two types The semi-curable sheet is matched with a laminated copper foil into the press to ultimately form a CEM-1 sheet.
