  • Patent number: 10403804
    Abstract: LED chip packaging assembly that facilitates an integrated method for mounting LED chips as a group to be pre-wired to be electrically connected to each other through a pattern of extendable metal wiring lines is provided. LED chips which are electrically connected to each other through extendable metal wiring lines, replace pick and place mounting and the wire bonding processes of the LED chips, respectively. Wafer level MEMS technology is utilized to form parallel wiring lines suspended and connected to various contact pads. Bonding wires connecting the LED chips are made into horizontally arranged extendable metal wiring lines which can be in a spring shape, and allowing for expanding and contracting of the distance between the connected LED chips. A tape is further provided to be bonded to the LED chips, and extended in size to enlarge distance between the LED chips to exceed the one or more prearranged distances.
