Control static electricity
Electrical parts might be largely damaged by a static electricity generated by a current in a circuit. Recently, the electrical parts become smaller, and the small electrical parts easily get the influence of very small amount of current.
It is very important to prevent the static electricity generation and to remove the generated static electricity in manufacturing and transferring process. In that case, using anti-static materials has great advantage.
ANSI/ESD S541 classify materials surface resistance on the point of static electricity as follows,
Classification of resistance value for packaging materials by ANSI/ESD S541
|Resistance / Ω
This classification is specified for static electricity and different from standard classification of conductive and insulative materials.
The surface resistance of PBI Advanced Materials products is shown in the following table.
