<p>An electronic assembly has a substrate 1 with several conductive tracks 21 and with a switching matrix 30 within the thickness of the substrate. Several groups 5 to 12 of identical integrated circuits are mounted on the substrate, one circuit from each group being operatively connected into the assembly by the switching matrix. A processor 4 detects malfunction of a circuit and controls the switching matrix 30 to disconnect that circuit and operatively connect into the assembly an alternative circuit from the same group. <IMAGE></p> |
