WebNeedless to say, a normal PCB FR4-Tg is 130-140 degrees, the medium Tg is greater than 150-160 degrees, and high Tg is greater than 170 degrees. High FR4-Tg will have better mechanical and chemical resistance to heat and moisture than standard FR4. The higher the Tg value, the better the temperature resistance of the material, so high Tg is ... WebDec 1, 2024 · A typical operational goal is to keep the conductor temperature rise in your board within 10-20 °C. The goal in a high current design is then to size the trace width and copper weight so that temperature rise is kept within some limit for the required operating current. IPC has developed standards relating the appropriate methodologies to test ... WebMost often printed circuit boards are made of standard glass-epoxy laminate namely FR4 type, with an operating temperature from -50 to + 110°C, glass transition temperature T g of 135°C.
