PCB Materials and Specifications

Selecting the right base material is fundamental to ensuring the electrical, mechanical, and thermal performance of any printed circuit board. Each material comes with specific dielectric properties that influence signal speed, impedance stability, and overall reliability — especially in high-frequency and high-temperature applications.

At PCB Power, we offer a range of industry-recognized laminate and prepreg materials designed to meet diverse design and performance requirements. From standard FR-4 to high-Tg, low-loss, and high-speed materials, every option is tested and qualified to ensure consistent manufacturability and performance.

Below, you’ll find a detailed overview of the materials we provide — including their glass transition temperature (Tg), dielectric constant (Dk), dissipation factor (Df), and other key parameters. These values help engineers select the most suitable substrate for their application, balancing cost, signal integrity, and reliability across prototype and production builds.
