With the continuous upgrading of electronic products, the previous ordinary PCB materials can no longer meet the needs of all products. High TG PCB boards are loved by the majority of projects. So what is a circuit board tg board? What are the advantages of using this board? Let me talk about it in detail.

TG PCB Circuit Board Introduction

TG is the temperature resistance value. The higher the TG point, the higher the temperature requirements of the board during pressing, and the pressed board will be harder and brittle, which will affect the quality of the mechanical drilling (if any) in the subsequent process and the electrical properties during use to a certain extent. characteristic.

The general TG sheet is above 130 degrees, the high Tg is generally greater than 170 degrees, and the medium TG is about greater than 150 degrees. Usually the PCB board with TG≥170℃ is called high TG PCB Board.

Advantages of High TG PCB Board

1. When the temperature of TG PCB Board increases to a certain area, the substrate will change from "glass state" to "rubber state". The temperature at this time is called the glass transition temperature (TG) of the board. In other words, TG is the highest temperature (℃) at which the substrate maintains rigidity.

2. That is to say, ordinary PCB substrate materials not only produce softening, deformation, melting and other phenomena at high temperatures, but also exhibit a sharp decline in mechanical and electrical properties.

3. The TG of the substrate is increased, and the heat resistance, moisture resistance, chemical resistance, stability and other characteristics of the printed board will be improved and improved. The higher the TG value, the better the temperature resistance of the board, especially in the lead-free process, high TG PCB Board applications are more.

The above is an introduction to the meaning of TG in the circuit board and the advantages of High TG PCB Board organized by FASTPCBA. I hope it will be helpful to everyone. If there is any unclear points, please contact us. We have professional PCB PCBA engineers for you. answer.
