| 1. A printed circuit board device comprising:
a printed circuit board including a plurality of electrical components;
an edge connector mounted on a first edge of the printed circuit board, and electrically coupled to the plurality of electrical
components via trace leads;
a first slot extending from an edge of the printed circuit board on one side of the edge connector to a first end; and
a second slot extending from an edge of the printed circuit board on an opposite side of the edge connector to a second end;
wherein the first and second slots define an isolated area of the printed circuit board, which supports the edge connector;
wherein the isolated area is connected to a main section of the printed circuit board, which supports the plurality of electrical
components, via a neck, through which the trace leads extend; and
wherein ends of the first and second slots define an axis about which the isolated area is bendable relative to the main section
of the printed circuit board;
whereby any bending caused by the connection of the edge connector to a mating connector will be localized in the area between
the first and second ends, thereby isolating the electrical components from any stresses caused thereby.
