If you work with Printed Circuit Boards in your industry, you may or may not be familiar with the high-TG PCBs. Since the effective operation of your printed circuit boards is so important to your business, it may be in your best interest to understand a little bit more about high-TG printed circuit boards.

What Is High-TG?

Tg means Glass Transition Temperature. As flammability of Printed Circuit Board (PCB) is V-0 (UL 94-V0), so if the temperature exceeds designated Tg value, the board will changed from glassy state to rubbery state and then the function of PCB will be affected.

If working temperature of your product is higher than normal (130-140C), then have to use high Tg material which is > 170C. and popular PCB high value are 170C, 175C, and 180C. Normally the PCB Tg value should be at least 10-20C higher than working temperature of product. If you 130TG board, working temperature will be lower than 110C; if use 170 high TG board, then maximum working temperature should be lower than 150C.
