voltage traces and the transformer.
on the transformer’s secondary should be widely
separated. The high-voltage traces should also be
separated from adjacent ground planes to prevent
lossy capacitive coupling.

to prevent arcing. Moving these traces to opposite
sides of the board can be beneficial in some cases.
