Abstract
An exemplary method for manufacturing a heat sink includes steps: providing a base with a plurality of spaced protrusions formed thereon; providing a plurality of fins and bending a distal end of each fin to form a connecting end; fitting each fin between two adjacent protrusions correspondingly and attaching the connecting end of each fin to the base; and deforming each protrusion to press the connecting ends of two adjacent fins.
