non-pedestal and pedestal design
Note for Figure 2a:
1. Unless otherwise noted, the tolerance = ± 0.20 mm.
2. Pedestal MCPCB allows the emitter thermal slug to be soldered directly to the metal core of the MCPCB. Such MCPCB eliminate t he high thermal resistance
dielectric layer that standard MCPCB technologies use in between the emitter thermal slug and the metal core of the MCPCB, thus lowering the overall system
thermal resistance.
3. LED Engin recommends x-ray sample monitoring for solder voids underneath the emitter thermal slug. The total area covered by solder voids should be less
than 20% of the total emitter thermal slug area. Excessive solder voids will increase the emitter to MCPCB thermal resistance and may lead to higher failure
rates due to thermal over stress.

Mechanical Mounting of MCPCB
MCPCB bending should be avoided as it will cause mechanical stress on the emitter, which could lead to
substrate cracking and subsequently LED dies cracking.
To avoid MCPCB bending:
o Special attention needs to be paid to the flatness of the heat sink surface and the torque on the screws.
o Care must be taken when securing the board to the heat sink. This can be done by tightening three M3
screws (or #4-40) in steps and not all the way through at once. Using fewer than three screws will
increase the likelihood of board bending.
o It is recommended to always use plastics washers in combinations with the three screws.
o If non-taped holes are used with self-tapping screws, it is advised to back out the screws slightly after
tightening (with controlled torque) and then re-tighten the screws again.
Thermal interface material
To properly transfer heat from LED emitter to heat sink, a thermally conductive material is required when
mounting the MCPCB on to the heat sink.
There are several varieties of such material: thermal paste, thermal pads, phase change materials and thermal
epoxies. An example of such material is Electrolube EHTC.
It is critical to verify the material’s thermal resistance to be sufficient for the selected emitter and its operating
conditions.
Wire soldering
To ease soldering wire to MCPCB process, it is advised to preheat the MCPCB on a hot plate of 125-150oC.
Subsequently, apply the solder and additional heat from the solder iron will initiate a good solder reflow. It is
recommended to use a solder iron of more than 60W.
It is advised to use lead-free, no-clean solder. For example: SN-96.5 AG-3.0 CU 0.5 #58/275 from Kester (pn:
24-7068-7601)

About LED Engin
LED Engin, an OSRAM business based in California’s Silicon Valley, develops, manufactures, and sells advanced LED
emitters, optics and light engines to create uncompromised lighting experiences for a wide range of
TM
entertainment, architectural, general lighting and specialty applications. LuxiGen multi-die emitter and
secondary lens combinations reliably deliver industry-leading flux density, upwards of 5000 quality lumens to a
target, in a wide spectrum of colors including whites, tunable whites, multi-color and UV LEDs in a unique patented
TM
compact ceramic package. Our LuxiTune series of tunable white lighting modules leverage our LuxiGen emitters
and lenses to deliver quality, control, freedom and high density tunable white light solutions for a broad range of
new recessed and downlighting applications. The small size, yet remarkably powerful beam output and superior insource color mixing, allows for a previously unobtainable freedom of design wherever high-flux density, directional
light is required. LED Engin is committed to providing products that conserve natural resources and reduce
greenhouse emissions; and reserves the right to make changes to improve performance without notice.
