Heat Transfer in LED Assembly

Various types of thermal management products are available for dissipating heat in LED-based module designs.

The choice of one over the other depends on the amount of heat to be transferred and the configuration of the assembly.

In most instances, a thermally-conductive/ electrically-insulating pad will be the choice in transferring heat to either a heat spreader or a heat sink.

Fabrico has access to various families of materials developed for thermal management in electronic and optoelectronic assemblies. Options include both off-the-shelf or custom formulations in specified thicknesses and configurations, as well as a variety of materials:

  • conductive adhesives and greases
  • tapes
  • ceramic and metal-filled elastomers (also called “gap fillers”)
  • coated fabrics
  • phase-change materials
