Increasing surface contact with ambient air for more heat transfer

Aavid, Thermal Division of Boyd Corporation’s represents the broadest Heat Sink offerings available today, from small stamped aluminum heat sinks for cooling discrete semiconductors at the board level to extremely large advanced fin types and unique geometries.

In addition to hundreds of standard part numbers with thousands of options, Aavid provides custom cut and machined extrusions, high heat transfer heat sink assemblies, and industry-specific heat sinks. Our advanced manufacturing methods enable us to fabricate optimized heat sinks to meet demanding application requirements.

With our expertise in wide variety of thermal management technologies, we're able to design and manufacture heat sinks with other air cooling, two phase heat transfer, or liquid solutions to produce custom, more complete thermal management solutions specifically for your system. Two phase vapor chambers and heat pipes are common technologies paired with heat sinks to augment air cooling thermal performance.
