That's really looking good Ed. I hope that pressure adjustment isn't
so critical that you have a hard time getting good repeatability. Will
slight variations in board thickness be a problem?

On the first solder run, I had too much pressure and while the area of the solder paste deposit was excellent (even on the 0.25mm socket lands), there was too little quantity of solder to hold the hold the components in position.
The second solder run I used less squeegee pressure and it left (did not scope it out) a large volume of solder (too much in the case of the 0.25mm socket lands and they bridged). Solder wick may be able to get the excess solder out.
I have two more boards to experiment with - hopefully by the end I will have it down.
