As electronics designers and manufacturers continue to move toward smaller, faster and higher performing devices, the challenge of thermal management is steadily mounting. Less board space and increased operating frequencies are raising temperatures, and risking reduced device performance and reliability over time. To help electronics designers and manufacturers address these thermal challenges, Dow Corning is introducing two advanced new products to its proven line of (TIMs): Dow Corning® TC-5622 and TC-5351 Thermally Conductive Compounds.
Dow Corning TC-5622 Thermally Conductive Compound offers good thermal performance and improved stability against hardening or dry-out in end-use applications. Its optimized rheology eliminates the need for common solvent diluents in the formulation, which can evaporate over time. That translates into lower environmental impact in the manufacturing area, and more consistent product performance during processing and over the lifetime of the device. The proprietary filler in Dow Corning TC-5622 Thermally Conductive Compound results in a material with high bulk thermal conductivity, and the ability to achieve thin bond line thicknesses (BLTs). This ensures low thermal resistance in both thin and thicker BLT applications that demand high heat dissipation. Dow Corning TC-5622 Thermally Conductive Compound also has a relatively low specific gravity that results in a cost savings compared to many TIMs. The material offers a unique combination of high performance, stability, ease of use and low cost.
The company formulated its Dow Corning TC-5351 Thermally Conductive Compound to deliver consistently high performance in important electronics end-markets, such as automotive, power electronics, and high-brightness LED lighting applications. Its high viscosity formulation and optimized filler technology make it well suited for applications demanding resistance to high temperatures and large gap thicknesses. It is ideal for vertical applications requiring a thermal material able to remove heat without flowing out of the gap or changing viscosity as temperatures rise.
