What does the ‘TG’ symbol signify on the PCB specification sheet?

The glass transition temperature (Tg) is crucial for PCB substrates as it marks the shift from a solid to a rubbery state, impacting pressing conditions and resulting in varying board hardness. This transition influences mechanical drilling and electrical properties, with higher Tg enhancing thermal and chemical resilience.
