In all electronics manufacturing facilities, reducing the risk of electrostatic discharges (ESD) is essential to avoid damage to sensitive components and to production equipment – not to mention the personnel working in the production facility.
The normal range for humidity in an electronics manufacturing environment is between 30% RH and 70% RH. Some facilities try to maintain a constant moderate RH (~50%), while others may want a lower % RH due to humidity-sensitive parts.
Thus, the ideal humidity level varies depending on the ambient environment and is usually determined by the specifications of the devices and components being assembled.
Electrostatic discharges typically occur when air humidity drops below a certain critical value. Controlling air humidity will successfully minimize the risk of ESD, protecting both equipment and personnel and ultimately increasing productivity and preserving a consistent quality of the output. Optimal control of relative humidity is best achieved by installing an adiabatic air humidifying system, which not only ensures that static charges are kept at a minimum, but also has the additional benefit of free cooling to reduce excess heat generated locally by production processes.
In most cases, electronics producers must be able to document that their production takes place under strict control of indoor climate – and this is where humidity control plays a key role.
