High-TG PCB

High-TG PCB

Compared to standard FR4 materials, high-TG materials have a higher temperature resilience. The TG value (“glass transition temperature”) describes the temperature parameter [in °C] above which the base material becomes mechanically unstable. These materials are used wherever the PCB is exposed to particular temperature or current loads and a higher continuous operating temperature is required for the reliability of the PCB. It should be noted here that the continuous operating temperature (MOT = “maximum operating temperature”) does not correspond to the TG, but is usually approx. 20°C below due to a safety factor. We are happy to advise you on the selection of suitable high-TG materials. Areas of application are, for example, high-temperature electronics, automotive and industrial electronics as well as complex multilayers.
