TP High Frequency PCB

Introduction

Wangling’sTP material is a unique high-frequency thermoplastic material in the industry. The dielectric layer of TP-type laminates consists of ceramics and polyphenylene Oxide resin (PPO), without fiberglass reinforcement. The dielectric constant can be precisely adjusted by adjusting the ratio between ceramics and PPO resin. The production process is special, and it has excellent dielectric performance and high reliability.

Features

The dielectric constant can be arbitrarily selected within the range of 3 to 25 according to circuit requirements, and it is stable. Common dielectric constants include 3.0, 4.4, 6.0, 6.15, 9.2, 9.6, 10.2, 11, 16, and 20. 

The material demonstrates low dielectric loss, with a slight increase at higher frequencies. However, this increase is not significant within the 10 GHz range.

For long-term operation, the material can withstand temperatures ranging from -100°C to +150°C, showcasing excellent low-temperature resistance. It's important to note that temperatures exceeding 180°C may result in deformation, copper foil peeling, and significant changes in electrical performance.

The material exhibits radiation resistance and displays low outgassing properties.

Furthermore, the adhesion between the copper foil and dielectric is more reliable compared to ceramic substrates with vacuum coating.
