| description | A method for making a firmly-bonded connection involves a) providing an electronic component and a substrate having surfaces to be connected; b) applying a copper paste onto at least one of the surfaces and drying the layer of copper paste; c1) applying a solder agent onto the copper paste and arranging the component and the substrate in contact via the combination of copper paste and solder agent; or c2) arranging the component and the substrate in contact via the dried copper paste, and applying a solder agent next to the layer of dried copper paste; and d) soldering the arrangement. The copper paste contains (i) particles of copper, copper-rich copper/zinc alloy, and/or copper-rich copper/tin alloy containing a phosphorus fraction of 0 to ≤500 wt-ppm, (ii) solder particles which are tin, tin-rich tin/copper alloy, tin-rich tin/silver alloy, and/or tin-rich tin/copper/silver alloy, and (iii) vehicle. |
