Also need advice concerning soldering of a 120 pin, three row, right angle, 
through hole edge connector. The pitch is 1 mm, and the through hole copper 
collar is such, that the space between them is just a fraction of a 
millimeter. We tried to use our selective soldering machine, but whatever we 
do, the SnPb overbridges all the pins!  I'm not surprised, because the 
solder surface tension will not allow the solder to withdraw pin by pin. 
However, such connectors are made and sold plenty of, so they must be 
solderable, question is with what. The selective soldering machine's 'wave 
pot' is 10 mm across and the minimum wave top is 3 mm.  Does it help to cut 
the pins so that they are even with the board ?  Today, the pins protrude 
0.3 mms . Anyone who knows nothing?

PS. Will send a photo to Dr Gregory.
