Steve, I was out for a few days on travel, but wanted to share more
info with the group on this. Also, I have used the AMP calculations
successfully that was referenced on the Technet, for some of the first
PIH projects. One thing I did not see referenced was the fillet
requirement. Many times your criteria can live with less then 100%
fillet....Phil Zarrow (hello Phil, ya out there?) had some interesting
formulas that had a FACTOR in his equations based on the amount of
fillet required. He was pretty open to sharing this in the past, his
e-mail is [log in to unmask], or phone at 603-868-1754. Also, an
interesting alternative to PIH is solder-loaded headers, see this on
TEKA's website at w3.bbsnet.com/TEKA (that's an old address, they may
have a new one). Anyway, hope this info helps. Feel free to contact me
anytime if more questions, PIH is a pet project of mine. Regards.

<< Hey, Steve!
I've got an article in front of me that I pulled from AMP's web site
some time ago. It has lots of information that AMP developed for intrusive
reflow. The URL shown on the top of the sheet is
http://WWW.AMP.COM/product/articles/dd66.html. There are follow-on pages at
/dd66a.html, etc.
The only problem is, I can't seem to go back there by typing the
URL, and I can't find any such article on the AMP site by going to
product/articles. >>
Hi Greg!
You're not the only one who has directed me towards that article. It was
referenced in some archived TechNet posts I read too...it had to be there
somewheres since I seen so many references to it. I too had trouble finding
that article. But being the "sleuthy" guy I am, I found it!
Go to the main page http://www.amp.com, then click on the "products" tab at
the top of the opening page. When the next page opens towards the top
right-hand side of the page there will be a link called "Technology Journal",
click that and the next page that opens there will be a links column on the
left hand side of the page. Down towards the bottom there's an "other" link
just under "Technology", click "other" and viola, there's the article!
"Solder Volumes for Through-Hole Reflow Compatible Connectors"
Amp musta' re-arraigned things at their site, that's why it was so tough to
find...
Thanks!
-Steve Gregory-
P.S. Thanks too Scott, John, and Justin, for the articles you sent me as
well!
