Selective Solder may be a solution (Vitronic-Soltec and Ersa sell
machines)

These almost look like press fit connectors with pins that long.
How long do they protrude?
And they are soldered????

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!
