Aluminum Zipper Fin and plate Soldering Heat Sink

  Soldering heat sink is manufactured by combining the fins and base together to the reflow oven to get a heat sink assembly, as the extrusion technology has the fin density and thickness limitation, the soldering heat sink assembly can solve this issue to improve the thermal performance. The fins can be aluminum zipper fins, folded fins and L-fins, the thickness of the fins can reach 0.2mm and has little fin density limit which means the heat sink has more surface area to dissipate the heat to the air.

  The Process of aluminum zipper fin base heat sink

Aluminum zipper fins: Stamping the aluminum plate through the tooling die by high stamping machine to get a zipper fin heat sink assembly as designed, then do the nickel plating

Aluminum base: Machining the shape and dimension by CNC machines.

Soldering process: Assemble the aluminum zipper fins with aluminum base to the fixture tooling and to the reflow oven.
