Re: Inadequate spacing

If you have trace spacing you wish were larger for high voltage/field areas, coat the offending electrodes with some dielectric material and it'll improve the breakdown rating there.

Falls under the category of creepage & clearance; UL for example has different spacing expectations for different voltages depending whether there is coating or not.
