Aluminum Extruded Heat Sinks

Hundreds of standard configurations including TIMs and mounting hardware available for common semiconductor devices.

Aluminum Extrusion Profiles

Available in raw bar, cut to length, or machined to specifications. Hundreds of optimized profiles.

Max Clip Heat Sinks

Save assembly time and costs while improving thermal performance with this system utilizing specialized clips and highly engineered aluminum extruded heat sinks.

Stamped Heat Sinks

Heat sinks designed for cooling semiconductor devices on printed circuit boards (PCBs). Includes a variety of geometries, mounting options, and attachment types.

Zipper Fin Heat Sink Assemblies

Zipper Fins allow for high fin aspect ratios and more design flexibility. Zipper fins are extremely cost efficient in larger volumes.

Skived Fin Heat Sinks

Higher fin densities and fin aspect ratios typical of heat sink assemblies without the bonding interface resistance between base and fins. Available in copper and aluminum.

Die Cast Heat Sinks

Casting allows for near net parts in complex geometries to reduce post-processing and interface resistance in assemblies.

Bonded & Brazed Fin Heat Sink Assemblies

Fins are epoxied, soldered, or brazed into an extruded or cast base in order to achieve a higher fin aspect ratio and fin density, vastly improving thermal performance.

Folded Fin Heat Sinks

Folded Fins enable higher fin densities and increased heat transfer from a single stamped sheet assembled on a base. Folded fin stock is also found in Extended Liquid Cold Plates, Heat Exchangers, or available separately.
