  • Patent number: 7102225
    Abstract: An electrically and thermally enhanced die-up tape substrate ball grid array (BGA) package and die-up plastic substrate BGA package are described. A substrate that has a first surface and a second surface is provided. The stiffener has a first surface and a second surface. The second stiffener surface is attached to the first substrate surface. An IC die has a first surface and a second surface. The first IC die surface is mounted to the first stiffener surface. A plurality of solder balls is attached to the second substrate surface. In one aspect, a heat spreader is mounted to the second IC die surface. In another aspect, the stiffener is coupled to ground to act as a ground plane. In another aspect, the substrate has a window opening that exposes a portion of the second stiffener surface. The exposed portion of the second stiffener surface is configured to be coupled to a printed circuit board (PCB). In another aspect, a metal ring is attached to the first stiffener surface.

  • Patent number: 5972738
    Abstract: A PBGA package includes PBGA member, a stiffener ring, and a stiffener fixture which includes a retaining recess having a floor for receiving the stiffener ring and includes a ledge positioned above the recess floor for receiving the PBGA member. An adhesive layer is applied to the stiffener ring, which is adhered to the PBGA member. The stiffener ring and PBGA member are essentially coplanar to less than 8 mils. A top plate is placed on top of the PBGA member and the ring and member are secured together tightly.
