Wave Solder question | 21 May, 2012

I'm having an issue with a particular board we run in our wave solder. it has a USB connector with 4 pins that are 3mm x3mm square. we are constantly getting abridge across at least two of the pins, but sometimes all 4. I've run out of ideas on how to eliminate it. I've done the basic things, change flux pressure, slowed it down, sped it up, adjusted the wave. The rest of the board is fine. I will note it is on the trailing edge as it goes through the wave, and I have turned it 180 with no luck.

Thanks in advance
