Heatsink Thermal Design; key considerations for Electronics Cooling

Heatsinks are often perceived to be the magic answer to all electronics cooling challenges. A heatsink makes heat spread out, so that it passes to the air over a much larger surface area than it would otherwise. Air then carries the heat away, cooling the electronics that generated it. So, why not place a heatsink on top of any thermally critical component? Simulation can illustrate the answer. With a 3D thermal simulation and analysis tool, product designers can model a product, or part of a product, and then observe a wealth of information about the air and heat flow within and around it. Simulation aids informed decisions about how to use heatsinks and where to put them. Read White Paper here.
