Abstract
Abstract An arrangement for electrically decoupling IC-circuits by means of decoupling capacitors. A particularly simple and effective electical decoupling of such circuits is achieved by mounting, e.g. gluing, a metal foil (2) on the circuit. The earth connection (3) of the circuit is connected to the edge of the foil through a short conductor and each of the signal output (4) and supply conductor (5) is connected directly to the foil edge through a respective soldered chip capacitor (7, 8).

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
113 words
An arrangement for electrically decoupling integrated circuits (1) by means of decoupling capacitors located between an earth connection (3) and at least one of a signal output (4) and a supply conductor (5), characterized in that at least the major part of an upper surface or a bottom surface of such an integrated circuit (1) is covered with a metal foil (2) which is connected at an edge to the earth connection (3) of the circuit by means of a short conductor (6), and to at least one of said circuit signal output (4) and said supply conductor (5) via the decoupling capacitors (7, 8) which are also connected to the foil edges.
Claim 2
Dependent Claim
113 words
An arrangement for electrically decoupling integrated circuits (1) by means of decoupling capacitors located between an earth connection (3) and at least one of a signal output (4) and a supply conductor (5), characterized in that at least the major part of an upper surface or a bottom surface of such an integrated circuit (1) is covered with a metal foil (2) which is connected at an edge to the earth connection (3) of the circuit by means of a short conductor (6), and to at least one of said circuit signal output (4) and said supply conductor (5) via the decoupling capacitors (7, 8) which are also connected to the foil edges.
Claim 3
Dependent Claim
46 words
An arrangement according to claim 1, characterized in that one or more of the decoupling capacitors is/are chip capacitors (7, 8) soldered between, on the one hand, respective signal outputs (4) or supply conductor (5) and, on the other hand, adjacent points on the foil edge.
Claim 4
Dependent Claim
33 words
An arrangement according to claim 1 or 2, characterized in that the metal foil (2) is glued to one side of the integrated circuit (1) flush with the edges of said one side.
