Hello, Do you know a method for measure the humidity of PCB? I try with a measure of the weight before and after a cycle in an oven... Thank you.

I wonder if anybody could spec a conformal coating or simalar application, to protect PCB's at 90% humidity. Standard HPA from electrolube does not work if the humidity is in excess of 75%. Cheers

Our SMT production and storage area is air-conditioned, constant temperature is maintained but the humidity is not controlled , the raw SMT material is stored in a "Drier" cabinet, but since we assemble hybrid SMT and thru-hole PCB assemblies, the SM

We have a "McDry" cabinet. It works well.
