Abstract
A process for forming at least one local contact area of a substrate of an electrical component for contacting the contact area with a connector, in which the substrate, on the contact side, is provided with a sintered porous metal layer. To make available a mechanically durable, electrically faultless solderable contact area, it is proposed that the porous layer be compacted and/or removed in the contact area to be formed.
Claims15
A process for forming at least one local contact area of a substrate of an electrical component for contacting the contact area with a connector, wherein the substrate, on the contact side, is provided with a sintered porous layer consisting of aluminum or comprising aluminum, said process comprising one of the following steps (a)-(c):
- (a) partially removing and partially compacting the sintered porous layer by concentrated electromagnetic radiation in the contact area to be formed;
- or
- (b) compacting the sintered porous layer by concentrated electromagnetic radiation in at least one area of the contact area to be formed, resulting in areas with differing;
- or
- (c) first removing the sintered porous layer in the contact area to be formed on the outer side, and then compacting the remaining area, said removing and compacting being carried out by concentrated electromagnetic radiation.
