LUXEON LED Assembly and Handling Application Brief AB32 20121217 30
In some pick and place machines a simple modification can be made to the pick and place feeder to achieve optimum yield. One recommendation
to reduce damage to the silicone lens is to remove the shutter completely and shift the cover tape removal close to the pick-up nozzle. Figure 38
illustrates this recommendation.
In addition to making the above change, Philips Lumileds recommends an electrical (motorized) feeder rather than a mechanical/pneumatic feeder
because units can fall out of the tape pocket or become misaligned due to abrupt movements of the tape.
