A flexible multilayer construction (1000) for mounting a plurality of light emitting semiconductor devices (LESDs 100, 110, 120) includes a flexible dielectric substrate (200) comprising top (210) and bottom (220) major surfaces, and pluralities of corresponding electrically conductive top (300, 310, 320, 330) and bottom (500, 510, 520, 530) pads disposed on the top and bottom major surfaces, respectively. An electrically conductive via (400, 410, 420, 430) connects each pair of corresponding top and bottom pads, a side of each top pad partially overlapping a side of the corresponding bottom pad and a side of the substrate, such that in a plan view, each top pad fully overlaps the corresponding bottom pad.
