Abstract

A method of making a surface-mountable pixel engine package comprises providing an array of spaced-apart conductive pillars and an insulating mold compound laterally disposed between the conductive pillars on a substrate together defining a planarized surface. Pixel engines comprising connection posts are printed to the conductive pillars so that each of the connection posts is in electrical contact with one of the conductive pillars. The pixel engines are tested to determine known-good pixel engines. An optically clear mold compound is provided over the planarized surface and tested pixel engines. Optically clear mold compound is adhered to a tape and the substrate is removed. The optically clear mold compound, the insulating mold compound, the conductive pillars, the optically clear mold compound, and the tested pixel engines are singulated to provide pixel packages that comprise the pixel engines and the known-good pixel engines are transferred to a reel or tray.
