Hello All

We have 50-mil pitch two row TH connectors on some of our boards. The
direction of flow in wave is parallel to the row of pins. This part always
bridges on the last pins as there is lot of drag at the end. We also tried
to add a thieving pad at the end of the last pin in the direction of flow
to help, but the test results didn't help much. (only 50% yield).

Does anyone has experience with this case? Any help is appreciated

Thanks
Uday
