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.

Better Heat Transfer Easy Assembly

Increased Flexibility Less Soldering

With Saturn’s Flex LED kit,

the heat only has to travel

through 2 mils of polyimide

material and 1.4 mils of Cu

before reaching the heat

sink resulting in cooler LED

temps and quicker equaliza-

tion times.

Better Heat Transfer from LED to Heat Sink

With current MCPCBs, the

heat must travel through 58

mils of insulator FR4 mate-

rial, 2 mils of adhesive and

10 mils of Aluminum before

it finally reaches the heat

sink, creating a slow migra-

tion of the heat from LED to

heat sink resulting in heat

backup and higher LED

temps.

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.
