High-Speed Low Loss Material

Risho’s high-speed low loss materials are made of PPE resin system with low profile copper which can achieve lower DK and Df for telecom and antenna application. PPE resin system has an advantage of stable Dk/Df, superior tolerance of thickness, high Tg, low water absorption and excellent process capability.
