1. What is Tg? Tg, or glass transition temperature, refers to the critical temperature at which PCB materials transition from a hard, brittle “glass state” to a soft, plastic “rubbery state” under heat. It can be simply understood as the melting point where the substrate begins to soften and lose rigidity. It is important to … Read more

Understanding the Tg Value of PCB Materials

When we submit PCB production data for prototyping, there is an option regarding the Tg value of the material on the online prototyping pricing page of the board factory. Different Tg values will affect the final prototyping costs, which means you have to pay for the Tg value of the material. So, what is this … Read more
