Summary: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 ).
