Low Loss Printed Circuit Board (PCB) on TU-883 Substrate and TU-883P Prepreg Multi-layer TU-883 PCB
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
General Description
ThunderClad 2 ( TU-883 ) 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.
