FR4 with high Tg: This type of FR-4 has a high glass transition temperature (TG) at 180℃. FR4 with high CTI: The relative tracking index is above 600 volts. FR4 without copper laminate: Suitable for insulating boards and board supports. WebMay 9, 2024 · Standard FR4 material with glass transition temperature Tg, which is approximately 130°C. This is the cheapest and most widely used FR4 material. FR4 material with a glass transition temperature Tg around 170°C - 180°C. This FR4 material is compatible with lead-free reflow technology.
WebA Printed Circuit Board is defined as high-TG FR4 PCB if its glass transition temperature (TG) is higher than 170 degrees Celsius. High-TG FR4 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 FR4 is more and more ...
