1. A thermal management system for electronic components, comprising:
- a first plurality of spacers disposed between a first flexible substrate and a metal plating, each of the first plurality of spacers physically contacting both the first flexible substrate and the metal plating, the first plurality of spacers including at least one pair of adjacent first spacers comprising a first spacer and a second spacer, the first spacer and the second spacer forming a first continuous fluid housing between the first flexible substrate, the metal plating, the first spacer, and the second spacer, and wherein the first plurality of spacers forming a first plurality of capillary pumping regions proximate to the first plurality of spacers and the first flexible substrate;
a second plurality of spacers disposed between a second flexible substrate and the metal plating, the second plurality of spacers including at least one pair of adjacent second spacers comprising a third spacer and a fourth spacer, the third spacer and the fourth spacer forming a second fluid housing between the second flexible substrate, the metal plating, the third spacer, and the fourth spacer, and wherein the second plurality of spacers forming a second plurality of capillary pumping regions proximate to the second plurality of spacers and the second flexible substrate;
a two-phase fluid disposed within some of the first and second fluid housings;
an RF conductor coupled to the metal plating, wherein the metal plating serves as a ground plane for the RF conductor; and
a plurality of electronic components coupled to a mounting surface of the first flexible substrate, the plurality of electronic components including at least first and second electronic components positioned directly over respective spacers of the first and second spacers with a gap separating the first and second electronic components.
