Neil,

  I tent vias to help prevent shorts.

  If a PCB is disposed towards growing dendrites then I would think there is
a serious cleaning problem.

Subject: [TN] Copper Dendrites

 

 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
