I doubt that this was copper dendrites.

Thanks everyone for comments so far - haven't been on Technet for a 
while so it was good to get such good responses.

Really miss Werner for questions like this...

Actually we have never seen a failure for dendrites; however, we have a 
customer who has a past problem with another supplier due to dendrites 
on PCBs and as a result wants us to cover vias with solder resist or 
conformal coating.

Tha,

Neil
