Standardized photon building blocks are packaged in molded interconnect structures to form a variety of LED array products. No electrical conductors pass between the top and bottom surfaces of the substrate upon which LED dies are mounted. Microdots of highly reflective material are jetted onto the top surface. Landing pads on the top surface of the substrate are attached to contact pads disposed on the underside of a lip of the interconnect structure. In a solder reflow process, the photon building blocks self-align within the interconnect structure. Conductors in the interconnect structure are electrically coupled to the LED dies in the photon building blocks through the contact pads and landing pads. Compression molding is used to form lenses over the LED dies and leaves a flash layer of silicone covering the landing pads. The flash layer laterally above the landing pads is removed by blasting particles at the flash layer.

A layer of Highly Reflective (HR) material is deposited by jetting microdots of the HR material in liquid form onto a substrate and then allowing the HR material to harden. In one example, the HR layer is the HR layer of a white LED assembly. The HR layer is jetted onto the substrate around LED dice of the assembly after die attach and wire bonding have been completed. The HR material can be made to flow laterally so that areas of the substrate under wire bonds are coated with HR material, so that HR material contacts side edges of the LED dice, and so that HR material contacts the inside side edge of a retaining ring. By jetting the HR material in this way, the amount of substrate that is not covered with HR material is reduced, thereby improving the light efficiency of the resulting LED assembly.

The current invention promotes accountability in reading, in terms of spatial, causal, temporal, protagonist, and intentionality elements of a story. A book with interactive maps was developed to emphasize the spatial and other dimensions of stories and encourage more spatial mental models, and generally more accurate situation models of the story. The interactive maps were printed on microdot paper and interspersed throughout the book, sometimes with successful completion of the activities required to obtain the page number of the next section of the book, which had been reordered in a non-sequential manner. Wireless electronic pens with cameras track X-Y location information from the microdot paper. Auditory feedback may be provided through a secondary device, like a personal computer, or directly using the electronic pen. The interactive book was tested on a group of sixth-grade students and found to reinforce spatial accountability.
