Product Introduction
Folded fins are made from bending aluminum and copper sheets before bonding to a base. These fins can be much thinner than typical extruded or bonded fins, and provide higher densities and surface areas. The folded fins are then attached to the heatsink base by brazing, solder or epoxy resin. Folded fin heat sinks are available in either aluminium or copper.
Manufacturing Process
1. Folded fin
2. CNC machining aluminum plate
3. Braze folded fin and aluminum plate, this process is pretty complex, the fins are very thin and is not very easy to brazed well for each fin. Pioneer Thermal has made thousands of this folded fin heat sink, we have made many failure parts in the past, but with constantly improving, now we are very successful at making this folded fin heat sink. If you have any folded fin heat sink inquiry, Pioneer Thermal is definitely your choice.
4. Surface treatment
5. Inspect, pack and ship.
