Abstract
A stress-free method and apparatus are provided for forming assemblies having thin substrates whereby a permanent non-interference fit low stress stud is positioned and secured evenly into a shallow hole of a thin substrate or host material without introducing uneven stress forces to maintain a flat surface on both sides of the thin substrate. The forces of inserting the stud are applied inward, towards a head portion of the tapered stud by a crimping tool adapted to move the substrate material inward and form a flange over the angled edges of the tapered head portion of the stud to secure the stud to the thin substrate. In doing so, the forces are absorbed by the strong tapered head portion of the stud which is able to withstand the crimping forces and will not be distorted by the inward crimping forces, thus maintaining flat surfaces of the substrate.
