Eric
Hopefully this does not come through as an ad... I don't work for, with, or
own stock in any of the following :-)
We use and are happy with TH lead forming equipment from GPD and Hepco (GPD
for axials, Hepco for DIPs). On the web at:
http://www.gpd-global.com/index.html and http://www.hepcoblue.com/
respectively.
Happily, all our SMT parts arrive formed. However, my colleagues in another
Litton plant have Fancourt equipment, and others have GPD equipment. Both
are happy with their equipment, and I believe there are relative merits to
both. Fancourt: http://www.fancort.com/
Also, if you want automated tinning equipment, talk to Russ at Winslow
Automation / Solderquik, they make an automatic unit (again, don't own one,
but I did see it in action and it's pretty slick).
http://www.solderquik.com They also do lead forming (in case you have just
a small requirement and want to contract it out).
You can contact me off-net if you want more detailed info on what we've got.

Subject: [TN] Lead Forming and Component Placement Questions
Hey all,
I've just been given instructions to research and reccomend the purchase of
lead forming equipment (both TH and SM) and TH component placement
equipment. Does anyone have any suggestions or comments on different types
of equipment. (Following all the rules of TN that people have been blasted
over recently!)
I also have questions about tinning components with respect to automated
lead forming. Is tinning usually done before or after lead forming? We are
working high rel and several of our contracts still spec NHB5300 and
MIL2000, so a blanket "No-tin" directive will not be acceptable to our
customers and quality folks. I am actually also working on developing a
reliable (read repeatable) method of tinning as our assemblers are doing it
by hand currently. (suggestions on this are welcome as well).
Thanks in advance,
Eric Kalgren
