Bonded Fin

Bonded Fin Heatsinks

Cooling Source manufacture bonded fin heatsinks with aluminum or copper metal sheets. Not only ..but by using an extrusion process. Consequently, the fins go through epoxy or a solder braze process. that is to say, the fin is bonded to the base, hence the name bonded fin.

CSI’s designed bonded heatsinks to help meet your particular needs. Should you have any questions about using bonded fin heatsinks, our knowledgeable consultants can discuss your specific needs and answer any questions you may have. It is essential to choose the right product for cost, delivery time, and effectiveness. The choice you make can be crucial to your success.

Also, bonded fin heatsinks are suitable for high-power applications. In addition, they provide low thermal resistance. Furthermore,  forced air cooling should be considered. 

Benefits and characteristics:

  • Better aspect ratio than thin fin extrusions
  • Rohs compliant and high thermal conductivity epoxy, or soldered fins
  • Fins can be as thin as 0.008. “
  • Fins can be 2 inches or higher
  • The solid mechanical bond between the base and the fins
  • Excellent process for large heat sinks.
