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.
