Abstract

Abstract: Thermal management in microelectronics components through micro pin-fins heat sinks is well understood. This work aims to propose an unexplored methodology for fabrication of such MPFs having cross-sections in shapes of droplet, aerofoil, piranha and diamond of dimensions as less as 200 µm and height up to 1200 µm. Density of these pin-fins has been achieved more than 4 pins/mm 2 on brass plates. The methodology is basically a retrieval of µEDM which has been combined with LASER micromachining to achieve the goal. Research directions for possible improvement in 'quality of the pin-fins' and 'material removal rate' have been proposed at the end.
