Hi Rich!
Finally got your picture, and it's posted. Go to:
http://www.stevezeva.homestead.com/files/Solder_Bridging.jpg
This picture is pretty blurry, but it's clear enough to see that you
shouldn't be having bridging problems with this connector. It's a standard-pitch
dual-row connector, and there shouldn't be bridging problems with it.
Can you share with us the parameters for the wave that you're using?
Belt speed?
Pre-heat temperature?
Pot Temperature?
Flux Type?
I see from your web page that you have an Electrovert Econopak Plus 400 wave
machine, with a Sonotech spray fluxer. This machine should be capable of
waving that connector without bridges.
In the meantime, here's a link that has a pretty good troubleshooting guide
for wave soldering defects. It's based on IPC-S-816. It's not the end-all for
troubleshooting problems, but a good starting point.
