Conformal coating will provide protection from the outside conditions. This
coating is put on the board after the assembly process.

Subject:        [TN] PCB Corrosion

Is anyone having problems with PCB corrosion. We have a number of products
which are showing signs of corrosion on the copper tracks and planes. The
products concerned are in non-air conditioned  environment and varying
humidity situations. Does anyone know of a suitable method to protect PCBs
from external elements. I am keen to hear of any known solutions to this
problem.

Thanks
