Abstract: A process for the production of electrical circuits which include resistors (1) contacted by noble metals and electrically connected by way of conductor tracks of copper, and possibly dielectrics, wherein at least the contacts (2) of the resistors of noble metal and the adjoining conductor tracks (4) of copper are produced by applying pastes and sintering thereof, and wherein the operation of sintering the conductor tracks of copper is effected at temperatures below 850° C. and below the temperature at which copper forms a eutectic with the noble metal, in a nitrogen atmosphere, and there is an electrically conductive separating layer (5) between noble metal contacts (2) and conductor track (4).

Abstract: A process for producing an electrical component having a plurality of soldered-on plug contacts projecting at a right angle, in particular a semiconductor element arranged on a ceramic board, wherein the plug contacts initially remain joined at one side by an edge strip of the sheet metal band from which they are produced, until the solder join to a substrate is made, whereupon the edge strip is removed, wherein the position of the plug contacts is established by bending the edge of the sheet metal.
