Subject: Flyback Driver Board - Decoupling

Hi All

I am putting together a general purpose flyback (and other ferrite transformer) 
driver board.

The board is single-sided and there are several places where the positive supply 
comes close to the ground plane.

Would there be any benefit in adding extra decoupling capacitors in these 
places?  I'm using mostly SMD components and could easily add capacitors without 
changing the layout any.  If the answer is yes, what is a good value?

Cheers

M
