Sorry to be replying so late. Somehow, I missed reading this email.

Have you considered using solder preforms and reflowing them? I am going
that way for a similar situation. Unless you have a continuous load of these
jobs, getting an equipment just for one or two assemblies may not be
justifiable. On the other hand, by proper design of the preforms, the job
can most probably accomplished with consistent and repeatable quality.
Obviously proper control of the packing and storage of the preforms needs to
be managed.

Does anyone use Fancort soldering robots, or others table top models like
it? Do they work?
We have several connectors we have no way of running through the wave and
are wondering what the capabilities are. Can any robots solder 20 mil pitch
leads? You can imagine trying to hand solder multiple 60 and 100 pin
connectors on 200 boards at a time.

I have a surface mount 20 mil fine pitch Molex connector 53856-5010 and
53927-5010 on both sides of the board which connects with a screw and bolt
after soldering. We are having a hard time visualizing being able to solder
and keep aligned enough after second side reflow.
I really appreciate your help on this one.
