TG PCB
What are High TG PCB?
The glass transition temperature of high TG PCB is more than 170C. If the working temperature exceeds the designated Tg value of the PCB, the board will be changed from glassy state to rubbery state, the function of PCB will be affected. So high TG PCBs have high temperature durability than conventional PCBs.
Applications
Industrial electronics, automobile electronics, high temperature electronics.
