What is the Glass Transition Temperature of a PCB?
Editorial Team - PCB Directory
Jul 13, 2019
Tg or the glass transition temperature is the temperature at which the base material of a PCB starts to transform from a brittle/rigid form factor to a soft, elastic one. The Tg value of a printed circuit board usually depends on the substrate used. This is one of the factors that you must consider when selecting the substrate materials for your PCB. You should make sure that the temperature where your board will be used is about 20 degrees less than the Tg value of the selected substrate.
