Abstract
A heat spreader for printed wiring boards and a method of manufacture are disclosed. The heat spreader is made from a plurality of graphene sheets that are thermo-mechanically bonded using an alloy bonding process that forms a metal alloy layer using a low temperature and pressure that does not damage the graphene sheets. The resulting heat spreader has a higher thermal conductivity than graphene sheets alone.
