ABSTRACT:
Package for an LSI chip having a plurality of contact pads comprising a carrier and a cover. The carrier is formed of a base of an insulating material and has a generally planar area for receiving the chip. A cooling stud is mounted on the base and can be provided with one or more removable cooling fins. The stud is mounted on the base opposite the area for receiving the chip. Spaced leads are carried by the base and have outer extremities which extend beyond the base in a direction away from the chip and are free of the carrier and have inner extremities which are in close proximity to the area for receiving the chip. A grounding bus is carried by the carrier to facilitate electrical checking of the package.
