Adding primary filters

I wonder how many designs had a primary filter added and subseqently passed EMI only because components had to be moved to make room for the filter...

Looks like the second (improved) layout made space for additional magnetics (L100) .. but wasn't installed (instead a 100 ohm and a smt inductor/ ferrite bead was installed)

So the design is no longer the same size... (?) a compromise that many of us cannot obtain when faced with these problems...that helped get that 3x spacing improvement.

Design review for EMI is a good to step to have in these complex designs. Yes the PCB layout makes lot of difference. Thanks to advancement in EDA tools, you can do a trial run on the layout before releasing the gerbers for PCB manufacturing.

@dvandit: That was exactly the first thought that came to my mine when I read this. In this case I'd say the ends could well justify the means.  :)
