Flex LED PCB

Definition of Flexible LED Circuit Board
One of the fastest growing markets in the PCB industry is LED PCBs. Most commonly, these involve a single layer of circuitry bonded to a metal substrate (most typically aluminum or copper) by a thermally conductive heatsink. While this technology is great for planar applications, it does not bode well for 3 dimensional applications. One solution would be to eliminate the metal substrate and thermally conductive dielectric, and opt for a single or double layer flexible PCB. The thin flexible material will serve as a thermally conductive substrate since the common denominator between all of these substrates is that these are all simply polymers modified in one way or another.

Ideally, you could bond this flex circuit to a heatsink that is machined to your final shape, using a flexible Thermal Interface Material (TIM) in between. Remember, there is always a solution!
