Abstract:
A method of forming an electronic module, said method comprising:(a) providing a substrate having at least one integrated circuit chip mounted thereon,(b) providing a lid structure adapted to be sealed to said substrate, said lid structure comprising a principal lid member,(c) providing a shim and a customizable understructure material, said customizable understructure material being positioned between said shim and said lid member and said shim being between said customizable understructure material and said chip,(d) moving said lid member toward said substrate, whereby said customizable understructure material is deformed,(e) allowing said deformed understructure material to become substantially rigid,(f) moving said lid member and deformed understructure away from said substrate,(g) removing said shim from said deformed understructure, said deformed understructure being attached to said lid member,(h) applying thermally conductive, compliant material to said chip, and(i) sealing said lid structure to said substrate whereby said deformed understructure contacts said compliant material to provide a primary heat dissipation path from said chip through said lid member.
