LUXEON HR30
Assembly and Handling Information
Introduction
This application brief addresses the recommended assembly and handling
guidelines for LUXEON HR30 emitter. This emitter is specifically designed and tested
for use in the most demanding environments and conditions. This emitter delivers
high efficacy and quality of light for distributed light source applications in a compact
3.0mm x 3.0mm package. Proper assembly, handling, and thermal management, as
outlined in this application brief, ensure high optical output and reliability of these
emitters.
Scope
The assembly and handling guidelines in this application brief apply to LUXEON 3030
HR30 with the following part number designation:
Where:
AA –
designates nominal ANSI CCT (27=2700K, 30=3000K, etc.)
BB –
designates minimum CRI (70=70CRI, 80=80CRI, etc.)
CC –
designated ESD protection level per JEDEC JS-001-2012 (00=2kV and 0T=8kV)
In the remainder of this document the term LUXEON emitter refers to any product in
the LUXEON product series listed above. Any handling requirements that are specific
to a subset of LUXEON emitters will be clearly marked.

IEC60950, clause 2.10.4). 1.6 Mechanical Files Mechanical files for the LUXEON emitter are available on the Lumileds website at www.lumileds.com. 2. PCB Design Guidelines for the LUXEON Emitter The LUXEON emitter is designed to be soldered onto a Printed Circuit Board (PCB). To ensure optimal operation, the PCB should be designed to minimize the overall thermal resistance between the LED package and the heatsink. -

2.3 Minimum Spacing Lumileds recommends a minimum edge to edge spacing between LUXEON emitters of 0.5 mm. Placing multiple LUXEON emitters too close to each other may adversely impact the ability of the PCB to dissipate the heat from the emitters. - Page 6 LED pads is then soldered on top of the flush area where the filled and capped vias are underneath it to create direct thermal path connection between LED and bottom of PCB.

5.2 Solder Paste Lumileds recommends lead-free solder for the LUXEON emitter 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. -

(tarnish) and leads to drop in light output and potentially weaken the wire bond adhesion strength over time. To test the robustness of LUXEON HR30 emitter susceptibility to corrosive environment, two test setups were evaluated: S exposure test per IEC 60068-2-43. Environmental condition: 40°C, H S 15ppm, 80% RH (relative humidity) up to 21 days. -

200ppb, all at 25°C 75% RH up to 21 days. LUXEON HR30 performs exceptionally well with average light output change of less than 10% and color shift of less than 0.006 points in delta u’v’ after 21 days in both test conditions.
