  • Patent number: 11189601
    Abstract: A mounting substrate has a patterned metal layer defining a plurality of top metal bond pads for bonding to bottom metal bond pads of LED dies. A solder mask layer is formed over the mounting substrate, where the mask has openings that expose the top metal bond pads and protects metal traces on the substrate. The mask layer is a highly reflective white paint. The exposed top metal bond pads are then wetted with solder. The LED dies' bottom metal bond pads are then soldered to the exposed top metal bond pads, such that the mask layer surrounds each LED die to reflect light. A reflective ring is affixed to the substrate to surround the LED dies. A viscous phosphor material then partially fills the ring and is cured. All downward light by the LED dies and phosphor is reflected upward by the ring and solder mask layer.

  • Patent number: 11164765
    Abstract: Die handling systems and methods of use for preparing or processing dies from multiple types of pre-expanded wafer materials. The die handling systems are configured in a modular fashion, allowing for concurrent processes to expand the wafers, process the wafers, extract the dies, and inspect the extracted dies without forcing one of the processes of the system to remain idle. Embodiments of the wafer handler module include a mechanism, such as an expander capable of stretching or expanding wafers having one or more different sizes to a pre-expanded state without interrupting the die handler. The pre-expanded wafers are stored as a proprietary cartridge and delivered to the die handler, where a pick head of the die handler removes each die of the pre-expanded wafer and delivers the extracted dies to subsequent machinery, such as a pick and place machine, for further processing.
