Assembly Precautions LUXEON XF-3535L emitter package contains a silicone overcoat to protect the LED chip and extract the maximum amount of light. As with most silicones used in LED optics, care must be taken to prevent any incompatible chemicals from directly or indirectly reacting with the silicone. The silicone overcoat used in the LUXEON emitter is gas permeable. Consequently, oxygen and volatile organic compound (VOC) gas molecules can diffuse into the silicone overcoat. VOCs may originate from adhesives, solder fluxes, conformal coating materials, potting materials and even some of the inks that are used to print the PCBs. Some VOCs and chemicals react with silicone and produce discoloration and surface damage. Other VOCs do not chemically react with the silicone material directly but diffuse into the silicone and oxidize during the presence of heat or light. Regardless of the physical mechanism, both cases may affect the total LED light output. Since silicone permeability increases with temperature, more VOCs may diffuse into and/or evaporate out from the silicone. Please refer to Application Brief AB203 for more details on VOCs and other incompatible chemicals. DS142 LUXEON XF-3535L Product Datasheet 20160402 ©2016 Lumileds Holding B.V.

The base dielectric is a 1-mil-thick polyimide layer with typical dielectric strength of 5.75 kVDC/mil. A highreflectivity high-reliability white coating with reflectivity of about 90% in the visible light wavelength range is applied over the flexible substrate. This coating has a typical dielectric strength of 2.85kVDC/mil. TIM/PSA Material LUXEON XF-3535L is included with a backside thermally conductive PSA (pressure sensitive adhesive). The backside PSA is designed to provide an improved thermal interface to the heat-sink. LUXEON XF-3535L adhesive has a typical 4kV dielectric strength (for this 0.1mm thick-layer). Recommended application process (Flex with backside PSA). See Application Brief for more details: 1. Use a new, lint-free swab and 50:50 mix of IPA and water to clean the mounting surface. 2. Remove the liner on the PSA. 3. Apply the tape to substrate with use of a squeegee, hand roller or finger pressure to help reduce the potential for air entrapment under the tape during its application. 4. The adhesion of the PSA to the mounting surface will reach 90% of its peak strength after 1 day. Heat and pressure can be used to accelerate the curing cycle. For example, good adhesion has been achieved by storing LUXEON XF-3535L for one hour at 80°C. Results may vary with different heat sink materials. Lumileds recommends that customers always perform their own testing. Connectors The LUXEON XF-3535L is available with optional electrical connectors. See Table 2 for standard options. There are two connectors positioned at the same end for the 10mm-wide Flex strips and two connectors at opposite ends for the 5.25-wide Flex strips. The AVX 9176-400 Series of connectors are Insulation-Displacement Connectors that allow direct wire to board electrical connection. The connectors allow the use of unstripped (insulated) wires, without soldering and can handle very high drive currents (up to 6000mA at Ta=105°C). Accepted Wire Gauge Size is: 24 Gauge Solid or Stranded. Optional white mating cap to cover the wire can be acquired from AVX (MPN: 609176001415100).
