Wow, laying out a board takes a LOT longer when you've got to document
and screenshot each mouse event.

We got a few boards where the contract mfr had mis-loaded their stuffing

A "tech" once fixed a board that had a bad dip device. Did he use the
same part that he pulled out? No he just got one that had the same
number of pins.

I had a factory build up boards where they put a high speed single
channel current feedback amplifier in a spot on my board where the BOM
called out for a dual jfet input general purpose

First, pin numbers are strings and thus letters can and are used.
Frequently bGA's will use leterf for either rows or columns and numbers
for the other.
Second, what is important between the symbol and the foot print is that
they agree on what the pins are called.
This brings up the other discuss

Oh sorry -- yes I was speaking of using letters for pinnumbers.

Hi Stefan,
we have pinlabels and pinnumbers, I guess your speaking about
pinnumbers?

Hello,
I have read that we can use single letters like "C", "E", "B" as pin
names -- this makes it simpler to assign the correct footprint to a
symbol.
On the other hand, default geda/pcb symbols/footprints seems to use
digits.
What is your advice? Is there a fixed correlation between numbers an
