Advantage:
· Lightest weight of all heat sink manufacturing methods
· Allows the thinnest fins (down to 0.1 mm thick)
· Allows more fins per inch of width
· Minimized mounting base thickness
· Maximum surface area per cubic volume for heat dissipation
· Very high aspect ratios
· Fins and base can be made out of different metals (copper base, aluminum fins)
Disadvantage:
· Requires joints which reduce thermal conductivity (diffusion bonded folded fin heatsinks offer much improved conductivity)
· More costly than skived fins or extrusion
· Some materials (aluminum) require nickel plating to allow soldering
