Assembly Precautions for the Nichia 193F Series LEDs
1. For the tape-and-reel feeder, the tape width is set to
24mm and the feeder pitch is set to 12mm.
2. Use a tape-and-reel feeder that ensures it does not
create excessive vibrations causing assembly issues.
Example: Electric (motorized) feeder
3. It is recommended to remove the top cover tape at
the recommended position shown in Figure 5 (i.e.
immediately before LED pick-up).
4. When handling the reel of the LEDs, ensure that
excessive force is not applied to the bonding ribbons
of the LEDs. Otherwise, this may cause the ribbons to
deform causing the LED to be damaged or not to
illuminate.

Figure 6. Recommended Nozzle Height for Pick-up Operations
1. Ensure that the nozzle goes down onto the LED in the tape pocket until the tip
touches the package (i.e. the black part).
Pick-up depth: 1.05mm
Note: If the reference level for the nozzle setting is at the edge of the tape pocket.
2. The recommended nozzle height for pick-up operations has been determined by
Nichia under specific verification conditions (see Table 9) and may not function as
expected with some other pick-and-place machines. If the pick-up operations are
unstable even with using the recommended nozzle height, adjust the nozzle height
appropriately for the pick-and-place machine being used.
If the pick point of the nozzle is too high,
- it may cause insufficient suction power leading to picking errors (e.g. the
nozzle’s failure to pick/lift the LED into the air, incorrect picking causing the
LED to tilt when in the air).
If the pick point of the nozzle is too low,
- it may cause issues (e.g. causing the embossed carrier tape to shake, causing
the tape pocket to deform) leading to picking failure.
