Abstract
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.
