Importance of TG value

TG value, namely glass transition temperature, is a key indicator for evaluating the performance of circuit board materials. It not only affects the performance of the circuit board in a high temperature environment, but is also directly related to the durability and reliability of the circuit board.

Choose the right TG value

In the design of multi-layer circuit boards, the selection of TG value is particularly important. High TG value is suitable for high temperature applications, while low TG value may be more suitable for general environments. Here are some selection guidelines:

• For high frequency applications, it is recommended to select materials with a TG value above 170°C.
• In high temperature environments, ensuring that the TG value adapts to the heat load is the basis for building a reliable circuit board.

Relationship between TG value and performance

The appropriate TG value not only improves the heat resistance of the circuit board, but also reduces the thermal expansion deviation of the material, thereby ensuring the long-term stable performance of the circuit board. Knowing this can help engineers gain an advantage in product design.
