DESPERATE for an Eagle library for 100TQFP for ATMega640/1280/2560

Hi Everyone...

I am desperate for an Eagle library that will work with the 100-TQFP footprint as used by the ATMega640/1280/2560 chips.

Crossroads and I are working on a project and had a library. Time for it is extremely tight, and today the board fabricator rejected the board. We have the error report from them. It appears that the library used has too small in the stop layer a gap between adjacent pins.

I'll attach the error report image they sent along with the actual report. Its clear from the attached pictures what the issue is. The thing pointed to by mark 'A' is the problem, the suggested solution is pointed at by mark 'B'.

Also, the fabricator suggests the pad size be reduced a bit to maintain 8 mil spacing. This is a very competent fabricator, so their advice is very well worth considering.

If someone could create a library that corrects this issue I would be eternally grateful! Feel free to PM me about it.

Thank you!

Jim

I just spoke with the guy who cuts my stencils, and he was quite happy with the paste layer generated by this library. Usually he tweaks things a bit, but he was quite happy with this as is.
