Hi Bill - thanks for the followup - it puts my faith back in a few physics
principles! I'll file this one in my unique but possible defects file.

Techies:

Thanks for your response to the above-mentioned topic.

As it turned out, the root cause of the problem wasn't as difficult or
"off-the-wall" as I originally thought it to be.  Steve Gregory hit the
nail on
the head.

Our assembly subcontractor splashed solder on the adjacent gold fingers
during
component replacement.  They used in-house gold replating operation to
resurface
the fingers and were a bit overzealous in the plating, causing the MELF
terminals to be inadvartantly coated along with the fingers with the "new"
gold.
