Lightweight packaging

A packaging system for electronic apparatus, comprising in combination:

• a laminated enclosure member,
• said enclosure member having,
• an, internal to said enclosure, heat generating signal processing device supporting lamination of printed circuit board material,
• an, external to said enclosure, wear resistant lamination of formic aldehyde resin material,
• a layer, positioned between said internal and said external laminations,
• said layer being of nickel foam metal,
• at least one heat generating signal processing device mounted on said internal lamination,
• a plurality of positioned holes through said internal and external laminations for entrance, exit and directing types of openings, for passing a coolant from and to outside of said enclosure, and,
• means propelling a coolant fluid from outside said enclosure and through said type openings returning to outside of said enclosure.

The method of packaging electronic apparatus comprising in combination the step of:

• providing a laminated enclosure member at least partially surrounding said electronic apparatus,
• said enclosure member having an, internal to said enclosure, signal processing device supporting lamination,
• said enclosure member having an, external to said enclosure, wear resistant lamination,
• said enclosure member having a layer of material positioned between said internal and said external laminations,
• said material having the combined physical properties of selectably interrelated coolant permeability and density, non-corrosiveness and electrical conductivity,
• mounting at least one heat generating signal processing device on said internal lamination,
• positioning a plurality of coolant flow holes in said internal and said external laminations, including,
• a plurality of coolant entrance holes through said external lamination and at least one hole through said internal lamination adjacent at least one said heat generating signal processing device,
• a plurality of coolant exit holes through said external lamination and at least one exit hole through said internal lamination, and,
• propelling said coolant serially through said entrance holes into said enclosure and out of said enclosure through said exit holes.
