In low-pressure plasma treatment the adherents are placed in a process chamber that is then evacuated. After introducing a process gas, the plasma is ignited by means of a high-frequency voltage or microwave excitation. The color, lightness and distribution of the plasma arc depend on the pressure in the chamber and the type of process gas used.

The plasma modifies the surface of the adherents, considerably improving the adhesion properties. Low-pressure plasma pretreatment is environmentally safe and allows components with a complex shape to be prepared for bonding.
