High-TG PCB Advanced Circuits Specification

The glass transition temperature of a printed circuit board, referred to as "Tg", indicates the point at which the PCB material will begin to transform. If the operating temperature exceeds the designated Tg value, the board will begin to change from a solid to a liquid state, which is likely to have an adverse effect on its ability to function.

Standard PCBs are manufactured with materials offering a TG value of 140°C, which can withstand an operating temperate of 110°C. While this may not be suitable for extreme-temperature processes that are commonplace in applications such as automotive, industrial or high-temperature electronics. In these situations, a PCB made from FR-4 material can often provide the best solution.

What Is FR-4?

FR-4 is a grade designation for flame-retardant fiberglass reinforced epoxy material. Thus, FR-4 PCB offers a much greater level of resistance to heat than a standard PCB. FR-4 circuit boards are divided into four classifications that are determined by the number of copper trace layers found in the material:

• Single-sided PCB / Single-layer PCB

• Double-sided PCB / Double-layer PCB

• Four or more than 10 layers PCB / Multilayer PCB
