TG 170 , FR4 Electronic Gold Plate High TG PCB Boards with Immersion Gold
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 material 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 boardwhich can go through -55~880C.

Heavy Copper PCB General Info
Heavy Copper Board does not have a set of definition per IPC. According to PCB industry, however, peopel generally use this name to identify a printed circuit board with copper conductors 3 oz/ft2 - 10 oz/ft2 in inner and/or outer layers. And Extreme heavy copper PCB refers to 20 oz/ft2 to 200 oz/ft2 printed circuit board
Heavy copper normally used for a various products but not limited to: high power distribution, heat dissipation, planar transformers, power convertors, and so on
Design Guide for Heavy Copper PCB
Typical conductor width/spacing/thickness tolerance is +/-20%, although tighter tolerance is achievable.
The minimum width and thickness of a heavy copper PCB conductor is determined primarily on the basis of the current carrying capacity required and the maximum permissible conductor temperature rise.
A circuit board trace, depending on its size and manufacturing process, may not be rectangular in shape. Heavy copper conductors can significantly add to the overall board thickness.
Additive (plating) processed are preferred to subtractive (etching) processes but are more expensive).
