Hi Phil,

I was thinking that Teka might have one of their solder bearing lead
stacking connectors that might fit the bill, then you just send it
through reflow.

These are .075" spaced pins which have gold stacking pins (.244")
protruding through a .063" PWB.  The top of the gold plated pins cannot
get contaminated with solder.

Hi Phil,

Can you give a part number of the connector? They aren't PC104
connectors are they?

Subject: [TN] Laser Thru hole soldering equipment

I have a technical challenge that I need some quick expert help with....

We need to automate a thru hole stacking connector and were hoping to be
able to use a laser soldering system.

How many of you out there actually do this type of selective soldering
already and what equipment is recommended?

The stacking connector requires special treatment as the gold contacts
cannot become contaminated with the solder.  We have three row
connectors which take a long time (few hours) to properly solder even
with the most experienced operators.  The center pins seem to be
impossible for the automated systems to access with the solder feed
systems.

Any help is appreciated.
