How do I classify high-TG materials?
Materijal | TG | MOT |
FR4-standard-TG | 130°C | 110°C |
FR4-mittel-TG | 150°C | 130°C |
FR4-hoch-TG | 170°C | 150°C |
Polyimid-Super-hoch-TG-Material | 250°C | 230°C |
ome common high-frequency materials do not mention TGs in their datasheets. This is due to the original meaning of TG: "temperature of glass transition". Many ceramics- or PTFE-based materials do simply not contain any glass fibres and therefore have no technical TG. Generally, this fact also applies to Polyimides (PI). However, you can usually assume a TG of at least 200°C for Polyimide, ceramics or PTFE-materials. In this case the TG simply stands for temperature resistance.
You may apply the following values:
Material type | Typical „TG“ |
CEM1 | 110-130°C |
FR4 | 120-180°C |
PTFE | 200-260°C |
Ceramic | 200-300°C |
Polyimide | 200-350°C |
