Abstract
An interposer member having strategically positioned apertures for electrically connecting an electronic device to a circuitized substrate. The member includes a homogeneous elastomer core having strategically positioned apertures. The apertures are positioned through the member approximately equidistant between adjacent plated through holes and/or conductive pads. Such positioning relieves stress from the plated through holes and/or conductive pads, and increases the contact compliancy of the member.
