Abstract

An apparatus is described. The apparatus includes I/O structures having pads and solder balls to couple with a semiconductor chip, wherein, a first subset of pads and/or solder balls of the pads and solder balls that approach the semiconductor chip during coupling of the semiconductor chip to the I/O structures are thinner than a second subset of pads and/or solder balls of the pads and solder balls that move away from the semiconductor chip during the coupling of the semiconductor chip to the I/O structures.
