Abstract:
A process for fabricating a heat sink with high-density parallel fins, the process comprising:providing a metal block comprising a first base and a second base, said first base being rectangular-solid shaped, said second base being rhombus-shaped and disposed over said first base, wherein said second base comprises a first edge surface and a second edge surface inclined at a specific angle; cutting said second base from a position on the top surface of said second base and parallel with said first edge surface until said first base is reached, thereby forming an inclined sheet; adjusting said inclined sheet to be normal to the top surface of said first base, thereby forming a fin; and repeating said cutting and said adjusting to produce said heat sink with high-density parallel fins.
