ADVANCED THERMAL SOLUTIONS Zipper fin heat sinks protect thousands of components from the dangers of excess heat. Products are machined from thin sheet metal, typically aluminum or copper and are formed into custom shapes. The sheets are designed to interlock with a very narrow space between their layers. The fin assembly is wave soldered to a metal base forming a very rigid, lightweight heat sink. Zipper fin production process yields a lower cost heat sink than bonded fin designs, as bonded heat sinks require more expensive tooling to manufacture. Zipper fin heat sinks can also be made in high aspect ratio fin profiles, enabling taller, thinner and more tightly packed fins for higher cooling performance.
