Hm, that reminds me! If you’re designing your own PCB, some manufacturers will make the PCB out of aluminum for you instead of FR4. This is commonly used for high-intensity LED lights to help keep them cool.

Here’s some random info about them so you can see what I mean:

An alternative would be copper-clad polyimide adhered to the body. That also has better thermal properties than FR4.
