Hi,
Nice looking boards! What are the dimensions of the PS board?

Thanks,
Danny

Hi Danny,

letsee... (tries to find a ruler with inches)... 5-15/16" x 3-9/16" with mounting centres of 3-1/4" on the short side and 5-5/8" on the long.

Cheers!

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.
