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...
