Description:
Tg is 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.
High TG materials have better mechanical strength, dimension
stability, adhesiveness, moisture absorption, thermal
decomposition,
and thermal expansion than normal TG pcbs.
High Tg material (TG170) is also popular in LED lighitng industry,
because heat dissipation of LED is higher than normal electronic
components, however same structure of FR4 board is much cheaper
than that of metral core pcbs, like aluminum board.
