Device for checking the attachment of a circuit board on a carrier

Abstract

A device for checking the attachment of a circuit board on a carrier, in particular a housing, has on each attachment point a pair of mutually associated electrically conductive contact surfaces and an electrically conductive connecting arrangement, which connects the circuit board mechanically to the carrier and at the same time connects the electrically conductive contact surfaces of the respective pair electrically to each other. At least one of the electrically conductive contact surfaces of a pair is situated on the circuit board. The other contact surface may likewise be situated on the circuit board or, for an electrically conductive carrier, even on the carrier. The respective pairs of conductive contact surfaces and the electrically conductive connecting arrangement form an electric circuit, which may be connected in a series circuit or a parallel circuit. An evaluation circuit checks whether the electric circuit thus formed is closed.
