Claim 16:
17. A method for removing a metal layer from a lamination stack comprising:
generating a lamination stack by:
providing a core;
applying an adhesive layer to a top surface of the core;
attaching a first conductive-lubricant-metal structure to the top surface of the core via the adhesive layer, wherein the first conductive-lubricant-metal structure comprises a first metal layer having at least a top surface of conductive-lubricant or a bottom surface of conductive-lubricant, wherein a first conductive-lubricant layer of the first conductive-lubricant-metal structure is doped via adsorption of small molecules by growing the first conductive-lubricant layer on the first metal layer of the first conductive-lubricant-metal structure and causing a small molecule dopant to be adsorbed onto the first conductive-lubricant layer of the first conductive-lubricant-metal structure;
attaching a second conductive-lubricant-metal structure to a top surface of the first conductive-lubricant-metal structure, wherein the second conductive-lubricant-metal structure comprises a second metal layer having at least a top surface of conductive-lubricant or a bottom surface of conductive-lubricant, wherein a second conductive-lubricant layer of the second conductive-lubricant-metal structure is doped via adsorption of small molecules by growing the second conductive-lubricant layer on the second metal layer of the second conductive-lubricant-metal structure and causing a small molecule dopant to be adsorbed onto the second conductive-lubricant layer of the second conductive-lubricant-metal structure;

applying compression and heat to the lamination stack to form a Printed Circuit Board (PCB); and
removing at least a portion of the second conductive-lubricant-metal structure from the PCB.
