Almost all of my designs are power products, and I do it to maximise the heatsinking ability of the PCB.

Do you typically remove the soldermask as well (assuming there isn't a safety issue with the voltages present)?


That increases the chance of attracting dirt, grease, finger prints and all that. Can become ugly, to the point where a service guy doesn't want to touch it anymore. One guy told me that some patient interfaces can look like evidence pieces from a crime scene.
