Abstract: A coreless pin-grid array (PGA) substrate includes PGA pins that are integral to the PGA substrate without the use of solder.

Abstract: Embodiments that allow both high density and low density interconnection between microelectronic die and motherboard via Direct Chip Attach (DCA) are described. In some embodiments, microelectronic die have a high density interconnect with a small bump pitch located along one edge and a lower density connection region with a larger bump pitch located in other regions of the die. The high density interconnect regions between die are interconnected using an interconnecting bridge made out of a material that can support high density interconnect manufactured into it, such as silicon. The lower density connection regions are used to attach interconnected die directly to a board using DCA. The high density interconnect can utilize current Controlled Collapsed Chip Connection (C4) spacing when interconnecting die with an interconnecting bridge, while allowing much larger spacing on circuit boards.
