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.

Established in 1999, we own 3 modern factories in China.

Guangdong province - Shenzhen PCB Factory and Dongguan PCB Factory.

The total production capacity is 290,000 sqm/month.

Our main product is high precision multilayer circuit board. 

Also we are experienced in PCBA.

Advanced equipment and professional technical support provide quality product.

Certifications obtained include :

We sincerely pursue win-win business with customer all the time!
