Abstract: The present invention relates to a method of connecting two components by ultrasonic welding for producing a power semiconductor module, said method comprising the steps of: a) Aligning the components to be welded to form a welding interface (16); b) Aligning a welding tool (18) to the aligned components; c) Removably arranging a trapping material (20) at least partly encompassing the welding interface (16), whereby the trapping material (20) is a foam; and d) Connecting the components by activating the welding tool (18). The method like described above provides an easy and cost- saving measure in order to prevent particle contamination when performing a welding process such as particularly an ultrasonic welding process sue to scattered particles (20).
