High Tg PCB General Info

Tg means Glass Transition Temperature. As flammability of board 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 board 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. Here are some popular High Tg board raw materials in market:

S1170 & S1000-2: SYL (Shengyi Technology);

Also there're a lot of different hi-tg material not listed here, different country, different company prefer using different material. Please view datasheet for each of them to choose most suitable material for you. If without special notice, normally we will use S1170 from SYL.

170Tg is also popular in LED industry, because heat dissipation of LED is higher than normal electronic components, and same structure of FR4 board is much cheaper than that of MCPCB. If working temperature is higher than 170/180C, such as 200C, 280C, or even higher, then you'd better use Ceramic board which can go through -55~880C.
