ThunderClad 2C

Very Low Loss and High Thermal Reliability Material
Core: TU-883C; Prepreg: TU-883P C

ThunderClad 2C ( TU-883C ) is a very low loss category material based on a high performance resin. This material is reinforced with regular woven E-glass and designed with very low dielectric constant and dissipation factor resin system for high speed low loss, radio frequency and wireless applications. ThunderClad 2 material is suitable for environmental protection lead free process and also compatible with FR-4 processes. ThunderClad 2 laminates also exhibit excellent moisture resistance, improved CTE, superior chemical resistance, thermal stability and CAF resistance.
