High Tg material PCB 6 Layer High Tg Board| YMS PCB
High-TG PCB Advanced Circuits Specification
The glass transition temperature of PCB, 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 High TG material can often provide the best solution.

What is high Tg PCB material?
High Tg PCBs: Greater than 170°C with a typical range of 180°C to 225°C.
What is Tg and TD in PCB?
Tg is expressed in units of degrees Celsius (ºC). Decomposition temperature, or Td, is the temperature at which a PCB material chemically decomposes
What is standard Tg?
standard Tg:TG130-TG135°C
