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
