Abstract
A flexible chip carrier with contact pads on its upper surface matching those of the chip with said pads conductively connected to land grid array (LGA) pads on its lower surface matching the those of a card or PCB. The chip carrier is provided with a stiffening layer at the LGA interface. The stiffening layer is mechanically attached to the lower surface of the chip carrier. Holes are formed in the stiffening layer to expose the LGA pads. The holes are then filled with a conductive adhesive material. Compliant LGA bumps are applied to the uncured conductive adhesive material which material is then cured.
