Zusammenfassung:A manufacturing method of an LED comprises attaching an LED epitaxial wafer (LED wafer) to an expanding tape, dicing the LED wafer on the expanding tape longitudinally and laterally to a certain element size to divide into a plurality of LED elements, expanding the expanding tape to a certain size to form an enlarged expanding tape, placing respective pairs of element electrodes of the plurality of LED elements that are attached to the enlarged expanding tape on respective pairs of electrodes on a printed-circuit board assembly collectively to perform a bonding, and removing the enlarged expanding tape from the plurality of the LED elements.
