Black double sides printed circuit boards TG170

High Tg PCBs

For printed circuit boards exposed to high thermal loads, the necessary long-term operating temperature must be determined early on, in order to select an appropriate material. 

Tg Value

The glass transition temperature (Tg) is an important normative dimension for the base material that determines the temperature at which the resin matrix converts from a glassy, brittle condition into a soft, elastic one. 

The Tg value of the base material sets here an upper boundary, at which the resin matrix decomposes and a subsequentdelamination occurs. The Tg is thus not the value of the maximum operational temperature, but rather that which the material can endure for only a very short time.

A guideline for a continuous thermal load is an operating temperature approximately 25°C below the Tg.

When the glass transition temperature (Tg) is over 170°C, it is referred to as a high Tg material.

High Tg materials have the following properties:

·High glass flow temperature value (Tg)

·High temperature durability

·Long delamination durability

·Low Z axis expansion (CTE)
