LUXEON MultiColor
Module 2.5W
Assembly and Handling Information
Introduction
This application brief addresses the recommended assembly and handling
guidelines for LUXEON MultiColor Module 2.5W emitters. This compact 4-in-
1 package makes color tuning easier. Each channel is individually addressable,
enabling a large color gamut while simplifying the ability of getting just the right
color point. Proper assembly, handling, and thermal management, as outlined in this
application brief, ensures high optical output and reliability of these emitters.

  • Page 3: Component

    1.1 Description The LUXEON MultiColor Module 2.5W emitter (Figure 1) is a plastic molded lead-frame package with four anode pads, four cathode pads, and an electrically active thermal pad. The center thermal pad (pin 9) is electrically connected to the anode of Red LED (pin 3), as shown in Figure 1 below.

    Section 6. 1.5 Electrical Isolation The minimum creepage distance within the LUXEON MultiColor Module 2.5W is 0.5mm between pads of different electrical potential. It is important to keep sufficient distance between the LUXEON emitter package and any other objects or neighboring LUXEON emitters to prevent any accidental shorts.

Recommended PCB solder pad layout for LUXEON MultiColor Module 2.5W. 2.2 Solder Mask A stable white solder mask finish (typically a polymer compound with inert reflective filler) with high reflectivity in the visible spectrum will typically meet most application needs.

  • Page 6: Minimum Spacing

    Lumileds recommends lead-free solder for the LUXEON emitter. Good results have been obtained with lead-free solders such as SAC 305 solder paste from Alpha Metals (SAC305-CVP390-M20 type 3). However, since application environments vary widely, Lumileds recommends that customers perform their own solder paste evaluation in order to ensure it is suitable for the targeted application.

  • Page 7: Pick And Place

    Note that pick and place nozzles are customer specific and are typically machined to fit specific pick and place tools. Lumileds advises customer to take the following general pick and place guidelines into account: The nozzle tip should be clean and free of any particles since it may interact with the top surface of the silicone encapsulation of the LUXEON emitter package.
