Hi Neil,

Are you saying that you are getting "Copper Dendrites" growth?

I'd like to see a picture of a copper dendrite. A picture before and
after would be nice.

Sincerely,

 What is the view of covering vias with solder resist to prevent
dendrite growth?

This is an FR4 PCB with OSP finish, SMT reflow both sides and a few
through hole components soldered with a selective soldering process...

Thanks in anticipation of the help of the Technet!

Neil
