Transfer apparatus and transfer method for transferring light emitting diode chip
Abstract:
A transfer apparatus for transferring a plurality of light emitting diode chips, comprising a stage on which a first substrate having the plurality of light emitting diode chips mounted on one surface is placed, a work table on which a second substrate to which the plurality of light emitting diode chips are to be transferred is placed, and a push pin module for transferring the plurality of light emitting diode chips to the second substrate by pushing the other surface of the first substrate in a state that one surface of the first substrate and the second substrate are disposed to face each other, wherein the push pin module includes a plurality of push pin units each including a push pin for pushing the other surface of the first substrate, and the push pin module transfers the plurality of light emitting diode chips corresponding to each push pin of the plurality of push pin units to the second substrate at a time.
