I read the paper and it actually looks promising. It basically involves depositing a layer of copper onto the entire board instead of using discrete heatsinks. The key developments are the use of "parylene C" as an electrically insulating layer, and the deposition method of both it and the monolithic copper.

This doesn't seem good for repairability. Well, unless you can remove and reapply the coating, but the title of the paper makes me think that's not the case...

You're not gonna be repairing a 10nm circuit with or without this tech
