Flex LED PCB Kit / Printed Circuit Board Assembly PCBA for Light Emitting Diode Applications

Saturn Flex System’s Flex LED PCB Kit Better Heat Transfer Easy Assembly Increased Flexibility Less SolderingBetter Heat Transfer—Saturn uses thinner materials re-sulting in an 1,800% reduction indistance from LED chip to HeatSink.Easy Assembly — Saturn’sFlex LED PCB Kit includes apre-assembled rigid fixturewhich provides solid backing duringstenciling and reflow. The parts alsocome palletized in arrays so custom-ers can assemble multiple pieces at atime.Flexibility — Because the PCBs areflexible, you can wrap them aroundyour heat sinks.Less Soldering — The flex mate-rial takes the place of having to soldermultiple rigid PCBs together by pro-viding a connection that is 20 timesstronger than a solder connection.Turn 5 Rigid PCBs into 1 flex PCB.

Better Heat Transfer from LED to Heat Sink Current MCPCB LEDsWith current MCPCBs, the Significant heat backupheat must travel through 58mils of insulator FR4 mate-rial, 2 mils of adhesive and HEAT10 mils of Aluminum before SINKit finally reaches the heatsink, creating a slow migra-tion of the heat from LED to Cu.

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 PanelOnce chips are soldered to Flex PCB, use a stainless-steel cover-plate to mount the Flex PCB to your heat sink. The plate willgo over the top of the Flex PCB—not between the PCB andHeat Sink. The rigidity of the cover plate will ensure consistentcontact between the heat sink and PCB. HEAT SINK
