    • 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.
    • 用于检查电路板在载体上,特别是壳体上的附接的装置在每个连接点上具有一对相互关联的导电接触表面和导电连接装置,其将电路板机械连接到载体上, 同时将相应对的导电接触表面彼此电连接。 一对的导电接触表面中的至少一个位于电路板上。 另一个接触表面同样可以位于电路板上,或者对于导电载体,甚至位于载体上。 各对导电接触表面和导电连接装置形成电路,其可以串联电路或并联电路连接。 评估电路检查这样形成的电路是否闭合。
