Risk of electrostatic discharge (ESD)
Dry air with a relative humidity of less than 45% can lead to electrical charges during physical contact and within machines. Uncontrolled discharges can damage sensitive components.
Benefits
Condair humidifiers and dehumidifiers ensure ideal humidity in electronics manufacturing, preventing ESD damage, protecting product quality, reducing dust and improving employee health.
Reduce electrostatics (ESD)
Additional air humidification reduces electrostatic charges and protects sensitive components.
Standardised soldering
Controlled humidity protects against faulty soldering processes and solder joints.
Moisture damage protection (MSD)
Protection of moisture-sensitive components (MSD) during storage and in the manufacturing process.
Humidity Control for Electronics Manufacturing
Humidification protects the electronics industry
Additionally air humidification protects electronic components from electrostatic discharge (ESD), which can cause up to 25% of all malfunctions. A controlled humidity between 40% and 60% relative humidity are optimal, as they increase the conductivity of air and surfaces, thus allowing the static charge to leak to earth and preventing ESD damage.
Optimal humidity also ensures the quality of printing of the PCB, bonding and soldering processes in electronics manufacturing and guarantees reliable test results. If the humidity is too low, for example, the solder paste can dry too quickly, which impairs the strength of the solder joint and jeopardises the quality of the end product. In addition, optimum air humidity binds dust, improves the indoor climate, increases well-being and protects the health of employees from mucous membrane irritation and infections. Precise humidification therefore makes a significant contribution to process reliability, product quality and health protection.

Precise humidification therefore makes a significant contribution to process reliability, product quality and health protection.
Dehumidification for electronic manufacturing
Condair dehumidifiers also protect sensitive components, circuit boards and machines in the electronics industry from moisture damage. Moisture-sensitive components (MSDs) in particular place special demands on air humidity control. Even slight deviations from the optimum humidity level can lead to internal condensation, corrosion or short circuits.
Dehumidification protects MSDs from these risks and maintains their functionality. In the manufacture of printed circuit boards. The viscosity of the photoresist is crucial for the precise placement of the conductor tracks. Excessive humidity reduces viscosity, thereby affecting the thickness of the applied coating and potentially leading to faulty conductor tracks. In soldering processes, excessive humidity can also reduce the viscosity of the solder paste to such an extent that it flows away from its intended position.

Energy-efficient cooling in the electronics industry
In the electronics industry, machine waste heat and high process densities generate considerable heat loads that alter the indoor climate and jeopardise process stability. Adiabatic evaporative cooling offers an effective way of cooling production areas efficiently and in an energy-saving manner. Controlled evaporation of water removes heat from the air without sensitive components or materials being affected by direct moisture.
Evaporative cooling improves thermal stability in production rooms and prevents temperature-related quality fluctuations in the processing of solder pastes, photoresists and adhesives. The technology supports a constant ambient temperature, reduces thermal stress and at the same time improves the indoor climate for employees – a benefit for productivity, well-being and health.

ESD Protection
At a relative humidity of between 40 and 60%, electrostatic charges can dissipate without causing damage due to the increased conductivity of the air and materials.
Use cases
Precise humidity control protects against ESD, prevents condensation and ensures an optimal, healthy indoor climate in electronics manufacturing through evaporative cooling.
Anti-static and ESD prevention
Low humidity increases static build-up because dry air is an insulator, making electrostatic discharge (ESD) more likely. Maintaining 40–60% relative humidity helps dissipate charges and significantly reduces ESD risk.
In-duct evaporative cooling
Condair in-duct evaporative cooling provides adiabatic cooling and humidification in AHUs, reducing cooling load and energy use for data centres, HVAC and industry.
Prevent condensation and mould
By combining a professional ventilation system with the Condair DA adsorption dryer, it is possible to achieve optimal results in preventing condensation and mould.

Frequentis AG, Wien
Luftbefeuchtung in der Elektronikindustrie Das international tätige Hightech-Unternehmen Frequentis ist Weltmarktführer im Bereich der Sprachvermittlungssysteme für die Flugsicherung. Als Frequentis 2006 seine drei Standorte in einem neuen Firmengebäude in Wien zusammenführte, bekam das Thema Luftfeuchte eine hohe Dringlichkeit: Im ersten Winter haben wir eine relative Luftfeuchte von zeitweise unter 20% gemessen, erinnert sich Kurt Feuchtinger, Leiter Facility Management. Eine zu geringe Luftfeuchte erhöht die Gefahr von elektrostatischen Entladungen und Folgeschäden an Bauteilen und Geräten. Bei Frequentis in Wien gehört eine Direktraum-Befeuchtung seit 2008 zum ESD-Schutzprogramm. Über 50 Hochdruckdüsen-Luftbefeuchter vom Typ TurboFog sind direkt in den Montage-, Produktions- und Lagerhallen im Einsatz.
