Lum Wee Mei,
Have your vendor pinpoint a X/Y location for this 5/5 feature.
Then find it in your Gerber file and verify the Decode selected.
Another solution might be viewing the Gerber yourself. If you don't
have a Gerber viewer there are a few free ones on the WWW.

> I have a question regarding Gerber output. Most of our designs are done
> with 6/6 (trace/spacing). One one occassion, our regular PCB vendor
> called us up and inform us that they found some 5/5 on a particular
> layout. However, when we call up the layout on our workstation with grid
> at 1mil setting, we found that the so-called problem area to be a
> perfect 6/6.
>
> Recently, this problem cropped up again with another new PCB vendor.
> Once again, our layout show a perfect 6/6.
>
> Can anyone throw me a light on what could be the problem. My Mentor
> Graphics rep mentioned that it could due to the CAM system used by our

> Thanking in advance.
