Abstract
The device according to the invention is intended for controlling the electrical continuity of the equipotential branchings of multi-layer printed circuits. It comprises selectors of a model of printed circuit to be controlled in order to effect, by superposition with the latter, the selection from the assembly E of the conductor elements accessible on at least one of the outer faces of the circuit, of two distinct sub-assemblies Ei and Ec, such that E=Ei+Ec; means for scanning said selectors in order to effect, by displacements in contact with the latter, detection of the defects in continuity; and indicators for translating the state of the electrical continuity in the branchings.
