ABSTRACT:
There is provided a component for use in electronic packaging. The component is a composite having a graphite matrix which is infiltrated with a metal or a metal alloy and the external surfaces of the composite then coated with a metallic layer to provide environmental and mechanical protection. The packaging components are lightweight, have a coefficient of thermal expansion close to that of a silicon based integrated circuit device and further, have a high coefficient of thermal conductivity.
