'[EE] FreeDFM.com experiences'

FreeDFM.com is a service of Advanced Circuits, a US PCB
manufacturer.

We've used them in the past, and things seemed to go well.
This time, however, as I've been submitting my designs to
FreeDFM.com, it returns a ridiculous number of design
errors, which neither my CAD program nor another preview
program I've been looking at the Gerbers with see.

Does anyone have any experience with FreeDFM.com?  Am
I chasing bugs in their process?

I'm using Proteus 6.5 for CAD- I like it and it usually does a
good job.

They should've told you what the errors were.

I use BareBones (another 4pcb service) periodically, and they apparently send
that thru the freeDFM service anyway.  I found this out when they found a few
errors once, and notified me of them.  The report came with images of the
board and the description of the problems (apparently the top layer shifted a
few mils without the bottom layer and caused some traces to short).

Was nice that they caught it.

Cheers,
-Neil.

We use http://www.freedfm.com. Our CAD program puts text in the plots
(identifying which plot it is), and freedfm raises all sorts of clearance
problems on the text (the dot on the i in Obispo is too close to the rest
of the i). I look through the reported errors and, if there is nothing
other than the text, go ahead and order the boards. They turn out great!

I think it must have been some change at their end since the last time
I used it.  I asked for a callback, and they informed me that their system
has trouble with drill files (my CAD program generates + and - coordinates;
apparently, the extra + throws their system off).  Grrr.  It'd have been nice
of them to make mention of that little detail on their results pages, so I
wouldn't have wasted all the time I did.

So be warned!

Last time I submited a board it was in PADS, and the
only thing it was really complaining about was the
size of the silk screen.  Otherwise, didnt show up
anything that I wasnt aware of.  Give them a call and
talk to them, I did last time and it cleared up the
confusion.
