Techniques are described for reducing inductance in ball grid array (BGA)
packages for integrated circuits (ICs). The BGA package comprises a set
of contacts disposed near an outer edge of the BGA package that receives
signal lines and isolated power and ground lines. One area of excess
parasitic inductance within the BGA package is in the wire bonds that
couple the set of contacts to the IC. The techniques described herein
shorten the wire bonds in order to reduce the amount of parasitic
inductance. The techniques include extending traces from a subset of the
contacts inward into the BGA package toward the IC mounted. The wire
bonds then couple the traces to the IC, thereby electrically coupling the
subset of contacts to the IC. The presence of the traces substantially
reduces lengths of the wire bonds relative to wire bonds that directly
couple the set of contacts to the IC.
