ThunderClad 1

Hi-Tg Halogen free Low Loss laminate and prepreg
Core: TU-863; Prepreg: TU-863P

ThunderClad 1 High Tg halogen free low loss material is made of high performance epoxy resin and regular woven E-glass fabric, designed with low dielectric constant and low dissipation factor for high speed low loss and high frequency multilayer circuit board application. Unlike conventional low loss material using brominated resin as flame retardant. ThunderClad 1 achieves flammability class of UL94V-0 by incorporating nitrogen compounds in the materials. ThunderClad 1 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, low signal attenuation and eliminate the use of potential hazardous halogenated resins.
