Manual Handling

Use tweezers to grasp XLamp ML family LeDs at the base. Do not touch the top surface of the LeD with tweezers.

Cree recommends the following at all times when handling XLamp ML Family LeDs or assemblies containing these LeDs:

• 

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.

• 

Cree recommends always handling ML family LeDs with appropriate eSD grounding.

• 

Cree recommends handling ML family LeDs wearing clean, lint-free gloves.

In luminaire design Cree recommends the same principle. Cover exposed LeDs to protect them during luminaire instalation and routine 
maintenance. A transparent cover over the optical cavity of a luminaire is an example of this kind of protection.

In production environments, whenever possible, Cree recommends the use of a pick & place tool to remove the XLamp ML 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 90d urethane.

Cree recommends the pick & place tool shown below for XLamp ML Family LeDs.
