Abstract
Abstract An electrically conductive strap is connected to an electrically conductive first connector at one end and connected to an electrically conductive second connector at the other end. Both connectors are mounted on the substrate so that the connected strap extends over a portion of the mechanical component, or otherwise cooperates with the mechanical component, to secure the mechanical component in the desired position. Also, the connection between the strap and the first connector electrically couples the strap to the first connector while the connection between the strap and the second connector electrically couples the strap to the second connector. At least one of the connectors, the first connector for example, is also electrically coupled to a first reference voltage preferably available on the substrate. The electrical condition of the second connector may then be used to indicate whether the strap and therefore the mechanical component is in place on the substrate.
