The silver sintering agent in the shape of a layer-shaped silver sintering body having silver oxide surfaces (for short also referred to as “silver Sintering agent” or “l(fā)ayer-shaped silver sintering agent” hereinafter) can be produced according to the inventive method by (1) application, for example, by screen printing, stencil printing or spray application, from a silver sintering preparation onto a support substrate having a surface that is incapable of forming a sintered connection, (2) subsequent sintering of the silver sintering preparation thus applied while applying, or preferably not applying, mechanical pressure, followed by (3) detaching the layer-shaped silver sintering body thus formed from the surface of the support substrate. If no or only an insufficient silver oxide layer is generated on the surface of the layer-shaped silver sintering body after this sequence of production steps, for example by atmospheric oxidation, (4) a downstream oxidation step can be added for the purpose of producing or reinforcing a silver oxide layer on the entire external surface or on parts of the external surface of the layer-shaped silver sintering body. Oxidation processes as illustrated below can be used in this context.

Accordingly, the method according to the invention for the production of a silver sintering agent in the form of a layer-shaped silver sintering body having silver oxide surfaces comprises the steps of:

• • (1) applying a silver sintering preparation onto a support substrate having a surface that is incapable of forming a sintered connection;
  • (2) sintering the applied silver sintering preparation;
