I think this is a cool idea. I would think Protel would most certainly be
intrested in helping, it adds value to the product. They already have
standards in place and would want us to work to the same standards. That may
be the only drawback to Protel involvement, unless we agree with thier

While I understand the sentiment, boy do I just hate when people say such things...
After all, there are not all THAT many footprints. Components, yes, footprints...I
don't think so...

Andrew et al,
I get the feeling that many people think that there would not be too
many footprints. How many is not too many? My SMT+ footprint reference has
2474 footprints and adds at least 50 - 100 per year. Now a large number of
them would not typically be used by any one user but
wow, what ambition!
can you pls explain:
2 There is a conductive fence on the lowest layer as to avoid part placement
conflicts
a little more?
lowest layer = bottom layer?
and how does conductive help?

Dennis,
What I meant to say is that Protel offers up to 32 signal layers,
therefore the fence would be located on the 30th signal layer. since this is
a conductive layer you can set design rules or clearance constraints for
your components. It would solve the silk screen pad violations,

IMO, too many is a relative term. 2500 is nothing compared to the discrete number of
components available, footprint(s) aside.

Andrew,
please don't throw me into the simple nay-sayers, I have my doubts
about whether it could be accomplished amongst a group as diverse as ours,
but it can be done. My concerns would be more for the diverse opinions and
desired features within the library and coming to some consensus

A half-life of 33 million years. That's some powerful sh*t...

Im assuming that the existing PCB footprint libraries on the Protel website
would be a subset of this super library.
The libraries are:
BGA531 footprints in 9 libraries based on pin pitch
Through Hole 107 footprints in 5 libraries
QFP's 226 footprints in 12

For validation, on the PCB side, I used to place a 'scanned version' in
a translucent state, of the part over the footprint. I've been able to find
and correct many footprint problems in advance using this technique. If
such an ability was built into Protel a copy of the

Under no circumstances should the Protel libraries be copied! They
are riddled with errors (I'd list them all as unverified). For
instance, any metric pitch component that's been created with the
footprint wizard is likely to be wrong.
The biggest hurdle I forsee is the widely differing
