Thanks John,
Already had that video in my archives, any more sources or hints would
be very welcome.

starting from the end of August 2009 before that I
can not free the time.
Also I live in an European country and do this work for a living so I
have to charge a hour rate of around 40 euro to make enough for food and
shelter. I think it will be around a week of work.

Hello everybody,

I need to create save footprints for BGA's and other very small
components that probably go into reflow soldering. I would like

Hello everybody,
I am trying to create a footprint with a correct name using the IPC-7351
Naming Convention for Standard SMT Land Patterns.
But I am having some issues, i am using the below document
balls; body 13 x 13 x 0.9 mm SOT824-1
If somebody can check the footprint and name on errors I would be very
thankful this is the first time I am working with BGA's.

There is a new version of the naming convention, IPC-7351B Naming
Convention for Standard SMT Land Patterns,
that lists the various BGA types.
Dual pitch has Col Pitch x Row Pitch attributes
Staggered pins is BGAS
A C or N suffix is added for collapsing or non-collapsing
an example for the 54-pin TSOP II
footprint?
I got a lot more footprints to make, and I can use all the help, since
time is getting really sparse.

Hi --
As some of you know, I gave a lightening talk about the gEDA Project
at Ignite Boston 5 last week.
The Ignite * events are odd networking evenings for geeks (and related
marketing types) sponsored by the publisher O'Reilly in various cities
around the USA.

Where can I find a list of all of these commands?
http://pcb.sourceforge.net/manual.html
On the end on the manual there is documentation about the pcb commands,
hopes this helps you.
