Danny,

I assume you also provided the fab house and IPC-356 netlist to verify
your gerbers. (????) If not, DO! I'm hearing so many horror stories on
fab houses only doing gerber-gerber generated netlists for comparison!
We've been burned 3 times in the last 6 months! They've even done it
when we did provide the 356 netlist! Unfortunately for me, the vendor
selection is out of my hands, but we are learning what the "low-cost"
vendors do. I'm just happy we have some great fab houses in the So.Cal
area!  :)

Do provide an "electrical netlist" to verify the gerber files! And this
is especially true if you use 274X.

Good luck.

Mitch Morey

(P.S. you can get a SKILL routine for IPC-356 generation from the
Cadence SourceLink site.)
