I do wonder if micro cracks at the base of each fin slightly drop the thermal conductivity of the heat sink. Still, very cool zero waste approach.
that is also how they get the heat sinks to talk... "we have ways of making you talk," says the operator...
Wow, pretty cool, I was not familiar with his process. Thanks for sharing.
I met a supplier of heatsinks and they had skiving in their presentation. Now I know what it is! Thanks C77!
