Indium Corporation boasts an extensive portfolio of innovative, high-performance metal thermal interface materials (TIM), some of which will be featured at the impending TestConX conference in Arizona, USA.
The company’s indium-containing TIMs for burn-in and test offer superior thermal conductivity over non-metals, with pure indium metal delivering 86 W/m•K. Its TIMs are available as pure indium, indium-silver alloys and indium-tin, among others. The pure indium TIM can be clad with a thin aluminium layer on the side facing the device under test (DUT) to prevent the indium from adhering to the surface.
Indium’s suite of Heat-Spring solutions, featuring a compressible interface between a heat source and a heatsink, include:
Heat-Spring preforms
• Patterned to optimise contact with non-planar surfaces, delivering 86 W/mK thermal conductivity.
• Provides uniform contact between the burn-in head and the DUT.
• Provides more uniform thermal conductivity.
• Cleans with no residue.
• 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.
Heat-Spring HSD
• Designed for interfaces with tight surface control above 30 psi.
• Recommended for small, well-designed interfaces with flat, smooth, parallel surfaces.

Editor's Choice Manufacturing / Production Technology, Hardware & Services
Dross formation is an inevitable consequence of wave soldering. It occurs when molten solder comes into contact with oxygen, forming metal oxides that float on the surface of the solder bath. Over time, this oxidation byproduct accumulates and must be removed to maintain solder quality and process consistency.
