High temperature fr4
WebJan 19, 2024 · During the production process of FR4 PCB, the FR4 boards are laminated with copper layers at a specific temperature. It is ideal for insulation as well as for board supports with no laminated copper, and it has a higher TG of around 180°c. Question Why do people think FR4 material is the best material? WebFor example, FR4 has a high dielectric constant, but this depends on its thickness and resin content. The dielectric constant of FR4 is a vital determinant of mechanical and thermal reliability. As a result, FR4 dielectric constants are a critical component of circuit boards used in high-temperature environments, such as engine compartments.
