Having issues with 3-4-1. Slow Down The Feeding Speed For Avoiding Led Tilting Within The Cavity by Nichia? Read our step-by-step SMT maintenance solution below. If you require replacement feeders, nozzles, or sensors, contact SMTBOX for OEM-compatible parts.
3-4. Problem 4: LED tilting within the cavity due to vibration of the emboss carrier tape
When an excessive vibration is applied to the emboss carrier tape, LEDs may tilt within the cavities.
LEDs with a lens are susceptible to vibration, resulting in tilting, since its center of gravity is located higher.
3-4-1. Slow down the feeding speed.
The higher the feeding speed is, the more the vibration affects the LEDs within the cavities. When LEDs tilt within the cavities, please lower the feeding speed to decrease the vibration.
(For ref. Nichia recommends that the feeding speed should be a little slower than high speed.)
The carrier tape may be vibrated by an air feeder much more than an electric feeder.
Please select the feeder depending on the LEDs to ensure that they are properly mounted.
