Cree recommends the following at all times when handling XLamp 4550 & XR family LEDs or assemblies containing these

LEDs:
• Avoid putting mechanical stress on the LED lens.
• Never touch the optical surface with fingers or sharp objects. The LED lens surface could be soiled or damaged,
which would affect the optical performance of the LED.
Whenever possible, Cree recommends the use of a pick & place tool to remove XLamp 4550 & XR family LEDs from the
factory tape & reel packaging.
Pick & Place Nozzle
For pick and place nozzles coming into contact with silicone-covered LED components, Cree recommends nozzles be
constructed of non-metallic materials. Cree and several of Cree’s customers have had good success using nozzles
fabricated from Teflon or from 90d urethane.
Cree recommends the pickup tool shown below for XLamp XR family LEDs.
