PCB manufacturer China： What is High-TG PCB
As PCB manufacturer China know that，A high-Tg PCB is a board designed to operate in high temperatures. The Glass Transition Temperature (Tg) is an essential element of any epoxy. It is basically the temperature point where the polymer changes from a hard, glass substrate to a soft, rubbery substrate. The substrates for making High-Tg boards must be flame-resistant, meaning they soften instead of burning at the glass transition point (Tg).
The higher the Tg value, the higher the temperature requirement during lamination. The PCB becomes hard and crisp in such conditions, affecting the hole size and related electrical properties. Standard board materials soften, deform and melt at such conditions, and their mechanical and electrical properties deteriorate significantly.

The standard FR-4 Tg is between 130-1400C, medium Tg is between 150-1600C, while high-Tg is more than 1700C. The higher the Tg value, the excellent the board’s performance to heat, moisture, and chemical resistance.
