Impact of humidity on wave soldering process

How does a low humidity environment (<30%) affect the wave soldering process? Is there any impact to the solder joints?

Expert Panel Responses
Low humidity is not a problem and is recommended to keep the humidity level down to 40% or less in a electronics manufacturing environment. The problem is with higher humidity levels in that circuit boards will absorb higher levels of water and cause defects such as blow holes and even blistering of the PCB. If you are keeping <30% humidity in your factory that is a good thing for manufacturing in wave soldering as well as SMT glue and solder past printing.
