  • Patent number: 8324719
    Abstract: Disclosed herein is an electronic package system utilizing a module having a liquid contact material to prevent mechanically and thermally induced strains in an electrical joint. The conductivity of the liquid contact material provides electrical communication between the required electronic components of the package system. The ability of the liquid contact material to flow prevents the creation of stresses and affords an electronic package design tolerant of small displacements or torsions. Thus, the liquid contact material enables a floating contact with high electrical reliability.
