Abstract: In a method for connecting a housing cover to a cup-shaped housing structure for an electric machine, and a cup-shaped housing structure produced by means of the method, the cup-shaped housing structure has an opening and has an opening edge surrounding the opening. The housing cover is of cup-shaped form, wherein a collar of uninterrupted encircling form is integrally formed on a cup-shaped structure wall in the region of an opening edge, which collar points radially outward. In a first method step, the housing cover is at least partially inserted into the housing opening such that a channel is formed by mutually opposite regions of the housing cover wall and of the cup-shaped housing structure wall. In a further step, the channel is at least partially or completely filled with a sealing compound, which is in particular of elastic form, or an adhesive.

Abstract: An electronic subassembly encompassing at least one carrier substrate, an electronic circuit being embodied on at least one carrier substrate surface. The electronic subassembly encompasses at least one mechanical connecting boss that is connected, in a substrate connection region, to at least one of the carrier substrate surfaces. The connecting boss, conversely, has, on a side facing away from the substrate connection region, a terminating boundary layer which is made of a metal oxide and which is embodied to furnish an adhesive bonding surface for an adhesive layer in order to constitute an adhesively bonded composite assemblage with a join participant.
