High quality bonded fin heat sink
1.Product Introduction
Bonded fin heat sinks are an assembly of a grooved base with individual fins bonded into the grooves. This type of heat sink fabrication allows for higher fin densities and fin aspect ratios than what is manufacturable with extrusion methodologies, greatly improving thermal performance as compared to extruded heat sinks due to increased surface area. Bonded fin types can be constructed in a few ways. Grooved bases can be extruded, die cast, or machined. Machining can allow for additional features like embedded heat pipes, vapor chambers, or encapsulated graphite heat spreaders. Fins are either punched from coil stock or cut from thin plate stock. The fins are inserted into the base grooves and are joined by epoxy, brazing, or soldering.

2.Product Details
In very demanding power applications where significant heat is generated in a small volume, Methode's bonded-fin designs can meet your packaging needs by increasing the heat sink surface area without increasing volume, reducing thermal resistance by fifty to sixty-six percent. Bonding fins to a heat sink removes the design-limiting fin extrusion ratio found in extruded heat sinks.
