Abstract Connector structure for reducing the stresses created on a substrate (11) and on the bonding surface (22) at which a connector is attached. The connector has a tapered or beveled head (23) thereby tapering the stress away from the edges of the bonding surface and therefore away from the high stress areas of the substrate, preventing cracking and delamination problems that might otherwise result. The taperedhead geometry also allows greater flexibility in manufacturing the connectors particularly when fabricating pins using a coldheading process in that a greater shank diameter:pin head diameter ratio can be obtained.
