Hi Steve,
Sorry- my mistake. Reading too fast and thinking too slow.

Steve,
Is it possible to mask of the end of the pins before soldering?

Three row 59 position receptacle assy

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?

Steve

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.
