Ed,
I have 37 articles, a few power-point presentations, and 9 different
spreadsheets I use for calculating intrusive reflow stuff. Now, we
could either spend half of our day at the fax machine, or give a quick
reference to some good and readily available resources that provide
good starter material.
You were correct when you stated the forum is about helping each
other, but let's keep it as painless as possible.
BTW, I have Jim Blankenhorn's book, and it comes with excel
spreadsheets.Regards!

Why are we reccommending some books to this man anyway, why don't we just
help him out with the info. he needs. Isn't that what this forum is all about?
