A bare board prior to use in an assembly could have misregristration
problems, it could have insufficient etching of circuitry on inner layers, artwork
could be flipped, gross wicking and others.

After assembly and in use it could be the result of cleanliness issues
resulting in electrochemical migration.

Just a few of the many
