Bonded Fin

The fins are manufactured from aluminum or copper sheet metal or through extrusion and bonded to the extruded base, using epoxy or through a solder/ braze process.

• Designed for high power applications
• Low thermal resistance
• Forced air cooling required

Die Casting

A versatile process for producing custom designed aluminum heat sinks by forcing liquid metal under high pressure into reusable steel molds.

• Optimal for high volume production
• Can produce complex design
• Lower thermal conductivity

Extrusion

The aluminum block is pushed or drawn through a die to manufacture straight fins or cross cut heat sinks.

• Little or no secondary machining required
• Low tooling cost
• Low piece part cost
  

Folded Fin

The process is achieved by bending a strip of aluminum or copper sheets in an array of fins. The fins are then bonded to the heat sink metal base.

• Thin fin
• The base and the fin can be made of different material
• Light weight
• Low tooling cost

Precision Forging

The metal is pressed, pounded or squeezed under great pressure into high strength parts known as forging die. The process is normally (but not always) performed hot by preheating the metal to a desired temperature before it is worked.

• High aspect ratio
• Any fin type
• Aluminum or copper
  

Skived Fin

This machining process uses cutting tools and a controlled slicing technique to manufacture heat sinks from a solid block of aluminum or copper.

• High aspect ratio
• Thin fin
• Low tooling cost
• Unidirectional flow
  

Stamped Fin

This process manufactures fins by applying extreme pressure to a blank piece of aluminum or copper and forming into the desired height, thickness and shape. The fins are then bonded to the heat sink metal base.

• Low piece price
• Thin fin
• Limited thermal performance
• High tooling cost

Thermal Interface Material

Cooling Source works with a variety of specialty material manufacturers to meet your specific thermal requirements.

• Gap filler: Silicone gel filled with ceramic powder to increase thermal transfer
• Phase change: Solid pads at room temperature that melt at operating temperatures from intimate contact on the mating surfaces to produce low thermal resistance
• Pressure sensitive tapes: Thermal transfer with electrical isolation
• Grease Creates a thin bond line, low thermal resistance interface for great thermal transfer
