A guide that facilitates the creation of two bone tunnels for use during a \u201cdouble bundle\u201d cruciate ligament repair. The chuck includes a generally cylindrical body member having a nose section and a tail section. At least one report may be generated for the multiple OSI indications, with each report including at least one OSI indication for at least one subzone. The three dimensional ability to expand in height, width, and depth would allow the various sized models to adjust to fit virtually any size electronic component, and would fold flat for ease of packaging and manufacture. In an aspect of the invention, electronic product packaging for demonstrative use in association with a product comprises demonstration means adapted to demonstrate visually or audibly the use or capabilities of the product under the control of integrated circuit means. The test structure may include a plurality of test pads designed to physically stress conductive lines to which they are attached during thermal cycling.
