In times of scarce availability of components and materials, reworking takes on a very high significance. This is also the case in LED manufacturing, where irregularities in processed LEDs are quite litterally a negative eye catcher. Reworking faulty or incorrectly placed as well as defective LED-dies is a true challenge. Thus these sensitive, fragile and very small components, which are usually processed in tight packing densities, can only be removed and reworked with a great deal of knowledge, experience and skill.
However, with the right technology, this is possible. LED dies can be easily and successfully removed with a die bonding automation system in the rework configuration without damaging adjacent LED dies and affecting the solder or its surroundings. The debonding process is performed using a scrubbing function. This has been modified accordingly and allows the adhesion between the LED die and the solder to be broken using the heating temperature. After the LED die has been separated from the solder, the tool carefully picks it up. Subsequently, a new die can be installed.
