This application is a Section 371 of international Application No. PCT/EP2015/058441, filed Apr. 17, 2015, which was published in the German language on Feb. 4, 2016 under International Publication No. WO 2016/015580 A1 and the disclosure of Which is incorporated herein by reference.
The invention relates to a method for the production of a silver sintering agent having silver oxide surfaces, and the use thereof in methods for the connection of components by means of pressure sintering.
US 2010/0195292 A1 discloses electronic components having a silver electrode that is provided with an external silver oxide layer. The silver oxide layer can be used for direct connection by sintering of the electronic component to a surface to be connected to it, whereby the silver oxide is reduced to silver.
US 2008/160183 A1 discloses a sintered connection method, in which a composition that can be sintered into a conductive layer and comprises organically-coated silver particles and silver oxide particles is used to produce a snuffed connection between surfaces that are to be connected. The still sinterable composition can be present in the application form of an ink, a paste or a sintering preform in the form of a layer-shaped pellet.
EP 0 579 911 A2 discloses a method for producing slurry-cast isotropic composite materials based on copper. In this context, a mixed slurry is cast onto a suitable substrate, fired, sintered, and processed through cold-rolling and tempering steps into a massive band. The composite materials can be used for the manufacture of electronic components.
