<< Bob,

 what you just said interests me. It's an interesting point of view to match
 the components and the PCB like this. Can one find CTE compatibility
 criteria and data somewhere on the Web?

 We are running 2225caps on FR4 with no problem, never seen cracks.

Hi loan!

While eating lunch, I sent my puppa' dawg out and he came back with a few
things.

First one is: http://mems.isi.edu/mems/materials/
it's a site with the properties of 136 different materials and lists CTE,
density, diffusion coefficients, etc., etc...

The next one is a Owens Corning site at:
http://www.owens-corning.com/owens/composites/about/glossary/cte.html
and lists CTE's for a few of their fiberglass products

The next one is a site from a company called Contacts Metal Welding that also
has a materials database that lists out the properties of different
materials...the database is on the left-hand side of the page that you just
scroll down until you find what you're looking for. It's at:
http://www.cmwinc.com/cmwf.htm

Hope this'll help!
