Little knowledge - High Tg PCB
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.
Normally high Tg refers to high heat resistance in PCB raw material.
The standard Tg for copper clad laminate is between 130 – 140℃. High Tg is generally greater than 170℃, and middle Tg is generally greater than 150℃. Basically the printed circuit board with Tg≥170℃, we call high Tg PCB.
The higher of TG value, the better of pcb high temperature resistance.
