5.4 Pick and Place Machine Optimization
Table 2 below summarizes key pick and place parameters for the dedicated LUXEON LED nozzles based on Philips Lumileds internal test results.
Since pick and place settings vary between pick and place tools and vendors, Philips Lumileds recommends that these parameters are used as a
reference only.
Table 2.

Unlike other SMD electronic components, which generally have cubic shapes, a LUXEON LED has a silicone lens protrusion to enhance light
extraction. When the cover tape of the reel is removed, there is a possibility for the silicone lens to touch a part of the sliding/guiding metal plate or
the shutter of the feeder during indexing. This can lead to scratched or damaged lenses, see Figure 37.
Top of the reel
Figure 36. With the top of the reel being 0mm, the nozzle will over travel into the reel
by 0.2mm and 1.6mm, respectively, for configuration A and B of the LUXEON LED.
