    Indium Corporation ® is set to showcase its advanced metal thermal interface materials (TIMs) for burn-in and test at TestConX 2024, March 3-6 in Mesa, Ariz., U.S.

    As a global leader in high-performance metal thermal interface materials (TIMs), Indium Corporation will showcase selections from its array of high-performance metal TIM solutions.

    Renowned for their superior thermal conductivity compared to non-metals, Indium Corporation’s indium-containing TIMs for burn-in and test stand out, with pure indium metal delivering 86W/mK. These TIMs are available in various forms, including pure indium, indium-silver alloys, and indium-tin. The pure indium TIM can be optionally clad with a thin aluminum layer on the side facing the device under test (DUT) to prevent indium from adhering to the surface. Indium Corporation’s suite of standard Heat-Spring ® solutions, which feature a compressible interface between a heat source and a heat-sink, include:

    Heat-Spring ® HSD

    • The original and best standard option for interfaces with flat, smooth and parallel surfaces.
    • Designed for interfaces with tight surface control >30psi

    Heat-Spring ® High Profile Preforms

    • Patterned to optimize contact with non-planar surfaces delivering 86W/mK
    • Ideal for assemblies with an extruded, unfished heatsink
    • Recommended for immersion cooling and Burn-In applications
    • Provides uniform contact between the burn-in head and the DUT
    • Provides more uniform thermal conductivity
    • Recyclable and reclaimable

    Heat-Spring ® HSK

    • Recommended specifically for burn-in applications where multiple insertions are required
    • Provides uniform contact with low resistance for high-density heat loads
    • Typically clad with a thin diffusion barrier, which serves as the contact surface for burn-in and test applications
    • No staining or cracking
