Abstract

Shape-memory alloy connectors and methods are provided for enhancing conductivity of a plated through-hole of a circuit board. A shape-memory alloy connector, including a shape-memory alloy material in deformed shape, is inserted into the plated through-hole of the circuit board. The shape-memory alloy connector is expanded within the plated through-hole by heating the shape-memory alloy material to, at least in part, transition the shape-memory alloy material towards a pre-deformed shape of the material. The transitioning of the shape-memory alloy material towards the pre-deformed shape expands the shape-memory alloy connector outward, at least in part, against plating of the plated through-hole to enhance contact of the shape-memory alloy connector with the plating of the plated through-hole.
