Back in '97, a message was posted asking about dark spots on OSP surfaces.  The
message described it as looking like the "fungus" you would see on an old
orange.  These spots seem localized and are found on the BGA pads and annular
rings.  I would like to know if anyone has any more insight as to what it may
be, what causes it, and how to prevent it.  Aside form that single message and
single response back in '97, nothing else appears in the archives.

Any information would be greatly appreciated.

Thanks in advance,

Mark W
