That is fine, and EXPECTED but as long as we get what we spec in
the delivered product everybody meets the requirements and we have
happy customers/bosses.
As a rule (and this is my rule maybe not for all) I will provide the
board gerbers, the Fabrication drawing and an IPC D356 netlist file and an info
file that describes what I have sent with special notes not on the fab
drawing.
A good board house can utilize those (find/notify if there are discrepancies)
and produce a good board.
The rest of this posting is just YET another sales pitch from Mr. Lomax.
