  • Patent number: 11543104
    Abstract: Disclosed are RCLED lamp bead packaging process and RCLED lamp bead, which comprises steps of: dispensing a die-bonding glue, mounting a chip, baking, welding a bonding wire, dispensing a first layer of anti-reflection adhesive, baking, dispensing a second layer of anti-reflection adhesive, baking, and testing. Anti-reflection adhesive is dispensed in corresponding area to cover part capable of reflecting light in RCLED lamp bead and eliminate reflection effect effectively. The first layer of anti-reflection adhesive fills in specified area rapidly to achieve high production efficiency. The second layer of anti-reflection adhesive flows slowly after glue dispensing, so that the glue dispensing precision is improved and the light-emitting hole is prevent from being covered. When bonding wire is welded, a bracket is the first welding spot and a PAD of the chip is the second welding spot to achieve a lower radian of the bonding wire.
