Abstract
Abstract A substrate for integrated circuits which can be used for mounting different types of circuits indiscriminately by providing three kinds of conductive tracks, one for connection to one type of circuit, a second to another type of circuit and a third to either or both of such circuits. Each kind of conductive track is provided with a distinctive marking which indicates whether it can be connected to only one or the other of the circuits, or whether it can be connected to either one.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
155 words
A substrate for integrated circuits having first conductive tracks for connection to the terminals of an integrated circuit; second conductive tracks for connection to the terminals of another integrated circuit, the leads of said other circuit being different from said first-named circuit; third conductive tracks for connection to either of said circuits; such that said substrate can be used for either of said circuits; said first conductive tracks being provided with a distinctive sign indicating that they can be connected only to one of said circuits; said second conductive tracks being provided with a distinctive sign indicating that they can be connected only to the other of said circuits; and said third conductive tracks being provided with a distinctive sign indicating that they can be connected to either of said circuits; thereby facilitating the mounting of any of said circuits on said substrate and the checking operation once said circuit is assembled on said substrate.
Claim 2
Dependent Claim
155 words
A substrate for integrated circuits having first conductive tracks for connection to the terminals of an integrated circuit; second conductive tracks for connection to the terminals of another integrated circuit, the leads of said other circuit being different from said first-named circuit; third conductive tracks for connection to either of said circuits; such that said substrate can be used for either of said circuits; said first conductive tracks being provided with a distinctive sign indicating that they can be connected only to one of said circuits; said second conductive tracks being provided with a distinctive sign indicating that they can be connected only to the other of said circuits; and said third conductive tracks being provided with a distinctive sign indicating that they can be connected to either of said circuits; thereby facilitating the mounting of any of said circuits on said substrate and the checking operation once said circuit is assembled on said substrate.
Claim 3
Dependent Claim
26 words
A substrate as defined in claim 1, wherein said distinctive signs for said conductive tracks comprise different configurations at the end of each type of track.
