The material of a printed circuit board has a significant impact on the properties of the final product. FR4 is commonly regarded as the standard for printed circuit boards, but factors such as thickness and Tg value influence the reliability of the product in which the printed circuit board is used. Additionally, while aluminum-based printed circuit boards are more efficient in heat dissipation, Rogers material is more suitable for high-frequency applications. It’s important to select the correct material.
FR4 is a base material made from epoxy and fiberglass. It typically has a UL94-V0 flammability rating and minimal moisture absorption, making it suitable for nearly all standard applications. FR4 is commonly used as the base material for single-sided, double-sided and multilayer printed circuit boards.
Aluminum, as a base material, has higher thermal conductivity than most other materials. It’s commonly used in LED lighting or other applications where heat dissipation is crucial. A thin dielectric layer is applied to the aluminum, onto which copper adheres.
Rogers material is primarily used for high-frequency applications such as antennas, radar systems, and wireless communication equipment.
In addition to FR4, aluminum, and Rogers, we also manufacture printed circuit boards on CEM1 or CEM3, Flex, and Rigid-Flex materials. Other materials are available upon request.
