Stamped fin heat sinks are manufactured by the application of extreme pressure to a piece of aluminum or copper to produce fins of the desired height, thickness and shape, which are then bonded to the heat sink metal base.
Stamped fin heat sinks are often recommended when you require a thin fin with limited thermal performance. They are characterized by a high tooling cost and low cost per piece.
Our bonded fin heat sinks are manufactured from either aluminum or copper metal sheets, or by using an extrusion process. Using either epoxy or a solder/braze process, they are then bonded to the base. Each process is designed to meet specific needs and our knowledgeable consulting is always available to answer any manufacturing questions you may have.
Bonded fin heat sinks are generally designed for high power application with low thermal resistance. Forced air cooling is required for these products.
