ABSTRACT:
A method for making a heat sink device comprises the steps of 1) forming a base from punching an array of mounting holes in at substrates; 2) forming a plurality of cooling fin strips from a material sheet; 3) aligning and assembling each of the cooling fins to the corresponding mounting holes of the substrate; 4) punching deformation holes in the first substrate to fixedly secure the cooling fin assembled to the mounting holes; and 5) cutting a redundant material portion from the cooling fin strips.
