1. Saturn Flex System’s Flex LED PCB Kit
Better Heat Transfer Easy Assembly
Increased Flexibility Less Soldering
Better Heat Transfer—
Saturn uses thinner materials re-
sulting in an 1,800% reduction in
distance from LED chip to Heat
Sink.
Easy Assembly — Saturn’s
Flex LED PCB Kit includes a
pre-assembled rigid fixture
which provides solid backing during
stenciling and reflow. The parts also
come palletized in arrays so custom-
ers can assemble multiple pieces at a
time.
Flexibility — Because the PCBs are
flexible, you can wrap them around
your heat sinks.
Less Soldering — The flex mate-
rial takes the place of having to solder
multiple rigid PCBs together by pro-
viding a connection that is 20 times
stronger than a solder connection.
Turn 5 Rigid PCBs into 1 flex PCB.

3. Simple Assembly and Mounting
Assemble LEDs
Saturn’s flexible LED PCBs show up in a palletized tab-
routed array for mass assembly and mounted to a tempo-
rary fixture plate to provide solid backing for stenciling
and reflow.
Mount Panel
Once chips are soldered to Flex PCB, use a stainless-steel cover
-plate to mount the Flex PCB to your heat sink. The plate will
go over the top of the Flex PCB—not between the PCB and
Heat Sink. The rigidity of the cover plate will ensure consistent
contact between the heat sink and PCB.
