1. A method of creating a conductive-lubricant-coated PCB comprising:
providing a lamination stack, wherein the process to create the lamination stack comprises:
providing a core;
applying an adhesive layer to a top surface of the core;
attaching a conductive-lubricant-metal structure to the top surface of the core via the adhesive layer, wherein the conductive-lubricant-metal structure comprises a metal layer having at least one of a top surface of conductive-lubricant or a bottom surface of conductive-lubricant;
plasma doping a conductive-lubricant layer of the conductive-lubricant-metal structure by growing the conductive-lubricant layer on the metal layer of the conductive-lubricant-metal structure and immersing the conductive-lubricant-metal structure in ions from plasma, wherein the plasma comprises ammonia (NH3); and
applying a heat and a pressure to the lamination stack to form the conductive-lubricant-coated PCB.
