Taking a shot in the dark...... Are you using the correct oven profile for the connector? Solder tends to flow (wick) towards the hottest part of the connection/pin/pad it is on. It may be that the hottest part is the connector itself where the pi

Q1: You say that 0.008" of "slop" is un-doable; hence, the reasons for our failures. Any basis for that statement? A1: We're not even considering the accuracy of your placement machine. We base our comments on the gap between the hole and the connec
