Frequently Asked Questions
What is a high Tg PCB?
A high Tg PCB refers to a printed circuit board that is made from materials having a glass transition temperature (Tg) superior to 170 ° C, hence, it is ideal for high heat applications.
What is the Glass Transition Temperature (Tg)?
The Glass Transition Temperature is the temperature at which the PCB substrate material changes from rigid to the softened state.
What are advantages of High Tg PCBs?
They are featured with better stability, mechanical strength, and reliability, suitable for high- power and high-speed applications.
Which materials are commonly used in High Tg PCB?
At MOKOPCB, we use high quality materials such as FR4-TG170, FR4-TG180, and Rogers to fabricate high Tg circuit boards.
Can High Tg PCBs be combined with other materials like FR4?
Yes, MOKOPCB’s high tg fr4 pcb manufacturing expertise includes hybrid PCB solutions that combine High Tg materials with standard FR4 in the same board.
Can MOKOPCB support multilayer High Tg circuit boards?
Yes, we can manufacture multilayer High Tg circuit boards, which fit your exact design and thermal performance requirements.
What is the typical production timeline for High Tg PCBs?
For prototypes, we have a standard 5-7 days lead time. While mass production usually takes 7-15 work days.
