Have you profiled at the problem side of the part?

Thanks AJ, It is looking like a CTE issue.

How do you go about and what happens when you rework the poorly soldered pad?

I had this issue a few years ago with Kingbright LED's. The problem was extreamly random. When i changed to a different datecode my problem went away.

Hi, I checked out your component.They are differnet dimensions. You say you are not using the recommended overprint ? if this is the case, I would imagine that is your problem. If you want to contact me off line to discuss further plesae feel free.

Because it's always the same terminal of the same part that is affected, and the same component is placed in multiple locations on the board without problems, I would suspect the board itself.

Does the established joint still exist if once again re-touched by a soldering iron, or does it return to the original problem? Wetting issues on pad could be for many reasons and you could analyze with a cause effect diagram.

Is it possible you are putting boards in the oven with little spacing between them and the oven is not recovering fast enough? I only say this because the 12 zone oven works but the 6 zone oven does not.
