Custom Bonded Fin Heat Sink for High Power

Bonded fin heat sink is made by aluminum/copper base with individual fins bonded into the grooves. Bonded fin technique is a conventional high power heat sink manufacturing technique. The aluminum/copper bases can be extruded, die cast, or machined. Fins are either punched from coil stock or cut from thin plate stock.
