摘要： A method for riveting fins into a bottom plate of a heat dissipating device is disclosed. A punching device has a plurality of weights each of which is formed as a thin sheet. The punching device is installed to a fixture; a plurality of fins are spaced with a predetermined gap; and a bottom plate is formed with a plurality of trenches for receiving the fins. The method comprising the step of: positioning the bottom plate at the fixture; inserting the fins into the trenches of the bottom plate; inserting the weights of the punching device into the fins so that each space between two fins has a weight; and punching a backside of the bottom plate by a puncher so that as the bottom plate moves; the weights collide with and deform portions of the bottom plate between the fins to rivet the fins into the bottom plate, firmly securing the fins in the bottom plate.
