Disclosed embodiments include folded, top-to-bottom interconnects that couple a die side of an integrated-circuit package substrate, to a board as a complement to a ball-grid array for a flip-chip-mounted integrated-circuit die on the die side. The folded, top-to-bottom interconnect is in a molded frame that forms a perimeter around an infield to receive at least one flip-chip IC die. Power, ground and I/O interconnections shunt around the package substrate, and such shunting includes voltage regulation that need not be routed through the package substrate.
