HUIHE CIRCUITS High TG PCB has passed ISO9001 / ISO13485 /IATF16949 / UL/RoHS /REACH certification.   What Is A High TG PCB? Usually PCB circuit boards with Tg ≥ 170°C are called high Tg circuit boards. Generally, the PCB TG of the plate is above 130 degrees, the PCB high TG  is generally greater than 170 degrees, and the medium Tg is about greater than 150 degrees. The Tg of the substrate is increased, and the characteristics of the heat resistance, moisture resistance, chemical resistance, and stability of the circuit board will be improved and improved. TG [TG: The highest temperature at which the base material maintains rigidity (℃)],The higher the value, the better the temperature resistance of the board.   Advantages Of Usin...
