ABSTRACT:
A substrate has a plurality of circuit traces having ends which terminate in raised contacts and an integrated circuit (IC) chip has a plurality of circuit traces terminating in contact ends which engage the raised contacts when the IC chip is positioned onto the substrate. The substrate also has a plurality of raised features thereon which are higher than and spaced from the raised contacts. The raised features have tapered side surfaces for engaging vertically extending surfaces on the IC chip to guide the IC chip into place of the substrate and so that its contact ends are aligned with and engage the raised contacts.
