for FR-4

        hi,

        i think you need to do a sanity check on the data at this site.  for
        example, they state that the thickness of 1/4 oz/ft2 copper is 3
mils.  this
        is a typo.  the thickness of course is about 0.3 mils.  the
guideline on a
        lot of data you get on the internet is 'caveat emptor'.  i heard
once heard
        it said that there is a lot of information on the internet, but
knowledge is
        not guaranteed.

        Hi Barbara!

        Merix has a pretty decent page about FR-4 prepreg properties at:

        http://www.merix.com/main_res.html

        Click on DFM in the column at the left of the page when it opens...

        Hope this helps...
