Hi John,

You did not say whether the affected locations are randomly distributed or in 

the same general area.

In the later case, I would look for an area of very high convective flow 

blowing off molten solder, particularly, if more than one SJ is affected in some 

grouping.

Obviously, there has to be an answer—apply Occam's razor.
