Fastener detection for encased electrical assembly

A printed circuit board (PCB), comprising:

• a flat base including a plurality of securing apertures for securing the PCB to a housing;
• and
• a plurality of conductive traces formed on the flat base with two of the conductive traces having first ends electrically connected to a different one of two electrical contacts and second ends routed to different ones of the securing apertures, and wherein each of the remaining conductive traces are routed between a different pair of the securing apertures such that when each of the securing apertures receives a secured conductive fastener continuity is achieved between all of the conductive traces.

An assembly coupled to a mounting structure that has a plurality of receiving apertures, the assembly comprising:

• a printed circuit board (PCB) including a plurality of securing apertures for securing the PCB to the mounting structure, wherein the PCB includes a plurality of conductive traces with two of the conductive traces having first ends electrically connected to a different one of two electrical contacts that are electrically accessible from outside the mounting structure and second ends routed to different ones of the securing apertures, and wherein each of the remaining conductive traces are routed between a different pair of the securing apertures such that when each of the securing apertures receives a secured conductive fastener continuity is achieved between all of the conductive traces;
• and
• a cover for attaching to the mounting structure, wherein the cover obscures at least one of the conductive fasteners when attached to the mounting structure.
