Steve,
Practice saying the following, then make sure your bidding department can
say it as well.

"Thank you very much for the opportunity, but NO BID!"

Subject: [TN] How would you solder this Backplane?


Mornin' All!

One of the guys from our bid department asked me to come and look at a
backplane we're bidding on, and tell him how we would solder it? I went and
looked
at it, and I'm not sure how we would. Go to
http://www.stevezeva.homestead.com
and take a look at Backplane Topside, Backplane Backside, and Backplane
Backside Leads.

The leads for all the connectors protrude at least a half inch or longer out
the bottom of the board. I'm assuming they are that long because they get
wire
wrapped after the backplane is assembled. But how do you solder something
like that? Some sort of dip solder pot? Drag solder? I don't think I'm going
to
be able to solder a board with leads that long in our Electra wave solder.

I can tell board was mass soldered, and I'm thinking it was dipped somehow.
Because you can see tiny little peaks on most of the lead tips that go
straight
up and down. Is there such thing as some sort of dip solder machine?

Sorry for all the dumb questions, but I've never been around a backplane
like
this, and don't really know how something like this gets built.

Thanks!
