Humidity control and drying for circuit board storage facilities

It is generally recommended to maintain a relative humidity (RH) of between 40% and 60% in your electronic component warehouse to greatly reduce the risk of PCB damage.

Without a solution in place to absorb moisture in your storage facilities, your printed circuit boards can sustain a wide range of damage, including:

• Short circuits, which can cause entire sections of a board to fail

• Corrosion, which can reduce the performance or operation of a board

• Delamination, which can lead to layers of a PCB peeling apart

• Solder joint degradation, which can contribute to electrical failures

For corrosion prevention and PCB protection you can rely on, talk to our experts for bespoke recommendations on the best equipment for your setup.

Achieving the humidity levels needed to protect the health of your people, premises and electrical parts demands nothing less than professional desiccant dehumidification systems, or powerful industrial dryers in larger storage facilities.

Speak to our experts to discuss the requirements of your electronic component warehouse, so we can guide you towards the most fitting solution.

Electrochemical migration (ECM) is when conductive paths form on PCBs where they do not belong. This can lead to malfunctions, short circuits, and in extreme cases, even overheating.

While ECM can be triggered by various factors, high humidity is one of the most common, as it:

• Serves as a conductor for ions, creating conductive paths that should not exist

• Accelerates the rate of corrosion – another factor that contributes to electrochemical migration

Yes. It is recommended to install dehumidifiers in every PCB storage facility, as moisture-related issues can develop in any location.

Yes, our range of high-performance dehumidification systems are some of the most energy-efficient solutions on the market.

Combining decades of expertise, high-quality components and a steadfast commitment to European engineering, our solutions enable PCB warehouses to maintain ideal humidity conditions with unwavering consistency and minimal long-term running costs.

Yes – temperatures should be closely controlled throughout an electrical part warehouse. This is because:

• Temperature and humidity are closely connected, and drastic fluctuations can lead to corrosive condensation

• Overly high temperatures can directly damage your PCBs themselves, disrupting circuits and warping boards

• Uncontrolled operating temperatures can undermine the welfare and productivity of your workers

For the ideal controlled environment, our experts recommend keeping your facilities between 22°C and 27°C.
