Abstract:
1. An attachment system, comprising: a first substrate having a surface and a recess, the recess extending from an opening in the surface and terminating in a cavity located inside the first substrate, the opening comprising a first rectangular portion that is intersected by a second rectangular portion; a polymer structure with a first portion molded into the recess and the cavity of the first substrate, and a second portion extending above the surface of the first structure, wherein the first portion contained inside the recess and the cavity is operative to anchor the polymer structure to the first substrate, the polymer structure characterized by a glass transition temperature that defines a transition of the polymer from a deformable state to a rigid state during attachment of the polymer structure to the first substrate; and a second substrate and a second substrate having a surface and a recess, wherein a third portion of the polymer structure is molded into the recess of the second substrate, thereby anchoring the polymer structure to the second substrate.
