Abstract (en)

[origin: JP2020026794A] To improve the resistance of adhesive connections in a vacuum pump.SOLUTION: The present invention relates to a method of producing a vacuum pump (111), in particular a turbo molecular pump. With the method, first elements (163, 165) are connected to a second element (161) by an adhesive. In this case, the first and second elements (163, 165, 161) each have first or second adhesive regions (231, 232, 233, 234) provided for an adhesive, and then at least one of the adhesive regions (231, 232, 233, 234) is at least partially treated with plasma before connection.SELECTED DRAWING: Figure 1
