Abstract
A protective device for subassemblies having a substrate and at least one component to be protected which is disposed on the substrate includes at least one covering element for covering a subassembly. An expanded filler material fills at least one given space between the substrate and the covering element and provides protection against mechanical compression. A method of producing a protective device is also provided. An expandable material is applied to the substrate and is expanded after the covering element has been mounted.
