Abstract
A method and apparatus for interconnecting circuit board assemblies using memory metal wires mechanically inserted into through-plated holes. The invention has its application in the interconnection of stacked circuit board assemblies where kinked memory metal wires are stretched so the wires are substantially straight; inserted into axially aligned through-plated holes of circuit boards; and released so that the memory metal wires reform their original kinked shaped within the through-plated holes, forming an electrical connection between the circuit boards. Memory metal alloys are used in the construction of the kinked memory metal wires to take advantage of the pseudoelastic behavior of the alloys in the austenitic phase below the forming temperature range.
