TP600 2-Layer 19.6mil High-Frequency Thermoplastic PCB with ENEPIG Finish
1.Introduction
TP 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. TP refers to the smooth surface material without copper cladding, TP-1 refers to the material with copper cladding on one side, and TP-2 refers to the material with copper cladding on both sides.
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, 9.8, 10.2, 11, 16, and 20. The dielectric loss is low, and the loss increases as the frequency increases, but the change is not significant within 10 GHz. The corresponding part numbers are TP300, TP440, TP600, TP615, TP920, TP960, TP980 etc.
