Flex LED PCB Kit

Flexible LEDs provide better heat transfer and increased flexibility that reduces soldering as well as a palletized tab-routed array that allows customer to easily assemble multiple pieces simultaneously during mass assembly process.

  • Better Heat Transfer
  • Easy Assembly
  • Increased Flexibility
  • Less Soldering

Better Heat Transfer

Flex LED PCB KitSFS uses thinner materials resulting in an 1,800% reduction in distance from LED chip to Heat Sink. 

Easy Assembly
SFS’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 customers can assemble multiple pieces at a time. 

Because the PCBs are flexible, you can wrap them around your heat sinks. 

Less Soldering
The flex material takes the place of having to solder multiple rigid PCBs together by providing a connection that is 20 times stronger than a solder connection. Turn 5 Rigid PCBs into 1 flex PCB.

Better Heat Transfer from LED to Heat Sink

Significant heat backup


Current MCPCB LEDs

With current MCPCBs, the heat must travel through 58 mils of insulator FR4 material, 2 mils of adhesive and 10 mils of Aluminum before it finally reaches the heat sink, creating a slow migration of the heat from LED to heat sink resulting in heat backup and higher LED temps.

Alpha Heat Sink


Saturn Flex LED Kit

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 equalization- times.















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 temporary 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.
