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

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).
