I bolted mine down to my copper heat sink, no solder and it works fantastic. Going strong over 5 years.

Great video Jim!

Thanks, Jim! Will be doing this in a few days! 73!

Thanks for sharing this info! Appreciated! Where did u get the heat sink and copper spreader from?

[@chandlerdarius6380]

instablaster.

I've never seen this before. Is this better than using heat sink compound?

[@caaarloteamswift]

Much better. Just think of 400W of heat being dissipated through such a small footprint. Besides the thermal aspect, it provides much lower electrical impedance from source to ground.

This would be great to use with Smd mosfets and thin copper plate.
