A solder pad configuration for use in an IC package is described. Various
embodiments of the invention describe IC packages, lead-frames, or
substrate panels configured with generally noncircular solder pads at
their bottom surfaces. The noncircular shapes allow for greater surface
area than circular solder pads having diameters equal to a major
dimension of the noncircular shapes, while maintaining the same
metal-to-metal clearance between the pads and adjacent leads. This
increased surface area provides for stronger and more reliable solder
joints.
