Why Humidity in ESD Protection Areas is Critical
Customer asked: I would like to know if the production workshop is in a storage/working environment with a relative humidity of greater than or equal to 65% for a long time, what harm will it do to the component lead surface and other exposed solder coating surfaces? I was wondering what your recommended humidity levels are for ESD protection areas? If ion blowers are used in the work area, how can arcs not occur?
Reply: When components are stored in an environment with a relative humidity of 65% or above, the metal and its surface you mentioned above always need to be considered for corrosion. The recommended relative humidity range for a static control environment is approximately 35% - 55% RH.
In general, do not use ion generators that operate on the principle of corona discharge where explosives or munitions are stored or handled. Most manufacturers of corona discharge-based ionization equipment control the transmitter pins for safe firing so there is no need to worry about arcing issues. If you are currently using ion equipment that is arcing, shut it down and talk to your supplier to resolve the issue. All our ionizers are "arc-free" and "spark-free" safe products.
