Abstract
A PGA integrated circuit package includes a package substrate (12), a unidirectional electrically conductive elastomeric layer (14), a plastic tape layer (16) having a centrally disposed chip (18), an insulator layer (20), and a cover member (22). A plurality of metal terminal pins (24) extend from a bottom surface of the substrate (12) and protrude slightly above a top surface thereof to form terminal pin ends (30). The elastomeric layer (14) is deposited over the substrate (12) for engagement with the terminal pin ends (30). The tape layer (16) and the chip (18) are deposited over the elastomeric layer (14). The tape layer (16) has a metalized trace pattern deposited on its bottom surface. The metalized trace pattern terminates at its outer ends with spaced apart metal terminal pads (32) which are in substantially vertical alignment with the respective terminal pin ends (30). The insulator layer (20) and the cover member (22) are compressed to establish electrical interconnection between the terminal pads and the respective terminal pin ends through the elastomeric layer (14).
