TU-862S

Hi-Tg Halogen Free Mid-Loss Material
Core: TU-862S; Prepreg: TU-862P S

TU-862S High Tg halogen free Mid-loss material is made of high performance epoxy resin and regular woven E-glass fabric, designed with lower dielectric constant and dissipation factor for high speed mid-loss multilayer circuit server board applications. Unlike conventional FR-4.0 material using brominated resin as flame retardant. TU-862S achieves flammability class of UL94V-0 by incorporating phosphorus and nitrogen compounds in the materials. TU-862S material is suitable for environmental protection lead free process and also compatible with FR-4 processes. This green material is designed to achieve thermal robust, mid-loss signal attenuation and eliminate the use of potential hazardous halogenated resins.
