1.Introduction of TP series

TP material is a high-frequency laminate known for its unique ceramic and Polyphenylene Oxide (PPO) resin dielectric layer, which omits traditional fiberglass reinforcement. This composition allows for precise control over the dielectric constant (Dk), which can be tailored from 3.0 to 25.0 to meet specific circuit design needs. The material offers excellent dielectric stability, low loss, and high reliability.

 

The product naming convention indicates the copper cladding: bare substrate (TP), single-sided cladding (TP-1), and double-sided cladding (TP-2). Standard Dk values, such as 3.0, 6.15, and 10.2, correspond to part numbers like TP300, TP615, and TP1020, respectively.
