Q:What is the working temperature of the carbon fiber material in the mechanical structure?

Synthetic stone (carbon fiber board) is a kind of composite material made of glass fiber and antistatic high mechanical strength resin. A ring that gradually rises in temperatureThe ability to continue to maintain its physical properties in the environment so that it can achieve high standard results during peak soldering without distortion. High temperature nanocomposite materials (synthetic stones) are not separated from the substrate in a harsh environment for a short period of time at 350 DEG C and operating temperatures at temperatures of 260 DEG C. Synthetic stone can improve the quality of PCBA in wave soldering process, avoiding the pollution of gold finger or contact hole because of human touch.
