Why Not Just Shove a Heatsink on Top of it? Part 3: Pads, Vias and Undersinking
An appreciation of heat flow paths is a pre-requisite for good thermal design. If you attempt to augment heat flow where there is none then your expectations are as futile as your design skills. The real value of simulation for me is that it enables an insight into the behaviour of a proposed design (this is true for simulation of any design and any behaviour). Once you … [Read more...]
