Liquid-Cooled Test Socket Assemblies for Semiconductor ICs

The test socket assembly is divided into distinct functional zones: electrically insulating regions (frame body, cartridge body) and thermally conductive regions (metallic inserts at contact points). This segmentation allows each zone to perform its specialized function without compromising the other, resolving the contradiction between electrical insulation and heat dissipation.

The patent applies different material properties to different locations within the assembly. Thermally conductive metallic inserts are strategically placed only at contact points where heat generation occurs, while the bulk of the assembly maintains electrically insulating properties. This local differentiation resolves the contradiction by providing heat dissipation exactly where needed without sacrificing overall electrical insulation.

The patent preemptively addresses thermal degradation by incorporating thermally conductive metallic inserts into the contact points before testing begins. These inserts act as heat sinks that prevent excessive temperature buildup during repeated testing cycles, cushioning the assembly against thermal degradation and deformation that would otherwise limit productivity.

The patent converts the harmful effect of heat generation during testing into a beneficial outcome. By providing efficient thermal conduction paths through metallic inserts, the heat that would cause degradation is instead channeled away from sensitive components, allowing repeated testing cycles to proceed without compromising reliability. The heat, rather than being a limiting factor, becomes manageable and even useful for maintaining contact integrity.

The contact point region is segmented into a thermally conductive metallic insert embedded within an electrically insulating matrix or housing. This segmentation allows the metallic portion to conduct heat away from the IC chip contact area while the surrounding insulating material maintains electrical isolation, resolving the contradiction between thermal conduction and electrical insulation at the same location.

The patent employs composite construction at contact points, combining thermally conductive metallic materials with electrically insulating materials in a unified structure. This composite approach allows both thermal and electrical requirements to be satisfied simultaneously within the same component, eliminating the need to choose between contradictory material properties.
