HEATSINK AND ASSOCIATED METHOD OF MAKING THE SAME

Abstract: a method of making a heatsink includes positioning a cathode, which includes a build plate and a metallic foil supported on the build plate, into an electrolyte solution. the method also includes positioning a deposition anode array into the electrolyte solution, connecting the metallic foil to a power source, and connecting one or more deposition anodes of the deposition anode array to the power source. the method further includes transmitting electrical energy from the power source through the one or more deposition anodes, through the electrolyte solution, and to the metallic foil, such that material is deposited onto the metallic foil and forms at least a portion of a heat exchange feature of a heatsink. the heatsink includes the metallic foil and the material deposited onto the metallic foil.
