Joseph LavoieMy diodes arrived. Using a piece of recycled epoxy board I installed 40 1000 volt diodes in 4 series elements creating this Bridge Diode Assembly.

The epoxy board came from a hv supply on an old big screen tv set. I also gave your concern thought. I will also use a conformal coating to insulate the unit. Thanks for your input. Joseph.
Are you sure? yes | no
The leads of 2 diodes side by side as (they are in series) can have 2000V difference. The spacing you have on the PCB is significantly less than the industrial accepted "creepage" standards. You want to make sure that your PCB is very cleaned as surface contaminants could further degrade the insulation between the 2 leads. You can probably get away with that if your board is used in a dry environment.
