Electronics manufacturing involves the handling and assembly of several delicate, moisture-sensitive components. Maintaining optimal humidity levels during the manufacturing process is key for protecting these components from electrostatic discharge, de-soldering, and other occurrences that can decrease the quality of the final product. This article highlights the importance of effective humidity control for avoiding product damage and maintaining a safe work environment in electronics manufacturing facilities.
Reducing Electronic Damage with Humidity Control
In electronics manufacturing, both low and high humidity levels can have negative impacts on product quality as well as the safety of the work environment. Three major risks associated with incorrect humidity control are as follows:
- Electrostatic Discharge (ESD) – Electrostatic discharge describes the sudden release of static electricity when two electrically charged objects meet. In addition to damaging electronic components, ESD events can create significant safety hazards such as fires or explosions. Since low humidity levels increase the risk of ESD, it is important to maintain a humidity level of at least 30% when working with electronic components.
- De-Soldering – Low humidity levels can cause solder paste to dry too quickly, compromising the strength of the solder joint and reducing the quality of the final product. Conversely, elevated humidity levels can cause condensation to form within the components and facilitate short-circuiting. Proper humidity control minimizes these risks by maintaining a consistent relative humidity level that meets the facility’s specific process requirements.
- Brittle components – When a facility’s humidity levels are too low, components are prone to becoming brittle and weak. Keeping humidity levels in the appropriate range is key for maintaining the desired material properties.
The Benefits of Humidity Control in Electronics Manufacturing
Effective humidity control in electronics manufacturing is essential for the following:
- Maximizing production output – Proper humidity control ensures a more consistent product output, leading to greater production yields.
- Creating a safe work environment – Maintaining optimal humidity levels is critical for reducing electrostatic energy and minimizing the risk of explosions or fires.
- Prolonging the lifespan of components and devices – Tight humidity control ensures longer-lasting and higher-quality products by preventing corrosion, eliminating ESD, and keeping materials from becoming brittle.
- Maintaining compliance – Implementing an effective humidity control strategy is important for maintaining compliance with the electronics manufacturing industry’s strict requirements regarding the production environment.
The Optimal Humidity Level for Electronics Manufacturing
The ideal humidity range for an electronics manufacturing environment will depend on the following:
- Components – A facility’s humidity levels should be optimized according to the individual specifications and sensitivities of the components being manufactured and assembled.
- Location – The physical location of the application and the ambient environment will also influence the optimal humidity range. For example, applications in drier environments tend to require slightly higher humidity levels to avoid static discharge, brittle materials, and other issues caused by insufficient humidity.
For most electronics manufacturing environments, optimal humidity levels tend to range from 30% to 70%. The ideal humidity level typically depends on factors such as the ambient environment and the specifications of the electrical components and devices being manufactured. For example, maintaining a consistent relative humidity of 50% may be ideal for some manufacturing environments, whereas others may require slightly lower levels to avoid condensation and corrosion in highly moisture-sensitive components.

Standardized HVAC units are a reasonable air handling solution for facilities with typical comfort cooling needs and few special concerns. A custom HVAC system or environmental control unit (ECU) can cool specialty spaces and processes within a facility, integrating with a standard ECU. Here, we will explain why custom ECU/HVAC systems are better suited for specialized air handling challenges and offer unique benefits to your space or process.
Benefits of Customizing Your ECU/HVAC Unit
No two facilities are identical, so standard solutions cannot serve the needs of every application. Whether it’s a completely new system or designed to integrate with your existing air handling systems, a custom HVAC solution offers advantages not possible with standard units.
Adapts to Climate/Operating Conditions
Off-the-shelf HVAC units are standardized for installation in some environments. But, if your facility is located in an area that is colder, warmer, more humid, drier, or otherwise deviates from standard conditions, that system won’t perform as well. A customized ECU is specifically set up to work best in your precise environmental conditions. Custom systems can also be designed to unique specifications, such as explosion-proof, high filtration, pressurization, or rugged environments.
Targets Specific Applications
If you need to maintain a reliable cold chain, keep a server room cool, have special air filtering needs, or control precise temperatures, a standard HVAC system is insufficient. A customized ECU installation will not only perform better and maintain desired conditions, but it will do so more efficiently. Custom air conditioning can target specific rooms while keeping conditions comfortable for the rest of the facility.
An HVAC system too large (too much capacity) for its facility consumes more energy than necessary. A system too small for its facility (not enough capacity) constantly works at maximum capacity without effectively maintaining proper filtration, temperature, or humidity levels. A customized system can eliminate these inefficiencies and save on energy expenses. Constructing new buildings gives technicians the opportunity to customize the HVAC system according to the correct configuration of rooms, windows, doors, hallways, heat loads, and other factors.
Meets Code Requirements
Local and national codes for ventilation and safety are frequently updated, so a custom HVAC solution can make sure your facility keeps up with those changes and stays compliant.
Because they run based on the precise needs of a space, customized ECUs may also reduce environmental impacts and energy consumption versus a standard solution, while still meeting all the requirements for the space they are cooling. Custom HVAC contractors can recommend special designs, filters, or capabilities to improve indoor air quality and lower operational costs while complying with environmental standards.

Semiconductors are in almost every electronic device, from everyday items like smartphones and coffee makers to complex automobiles, defense equipment, and spaceships. Manufacturers make semiconductors in special semiconductor cleanrooms because the wafers are extremely sensitive to environmental contaminants.
Here we explore semiconductor cleanrooms in more detail, including all their design requirements.
Semiconductor Cleanroom Design: Meet Air Quality Standards
Semiconductor cleanrooms are enclosed environments located within semiconductor foundries or fabs, that have tight control over the following:
- Temperature change over time
- Airborne particles
Semiconductor facilities must precisely regulate these parameters to maintain the highest air quality standards, all while optimizing productivity. Following these standards is paramount as even a particle of dust can render a chip useless.
A proper cleanroom design must have a well designed HVAC system that focuses on temperature, humidity, filtration, and the attributes noted above to treat and circulate air within acceptable limits. Each machine may have individual exhaust systems for removing contaminated air and particulates. Every cleanroom must be able to control particulate matter, static, outgassing, and equipment failure, which can lead to contamination events. These failures can include power glitches, pressure malfunctions, fan motor failure, and wafer handling machine breakdowns.
Controlling Temperature, Humidity, and Airflow
Semiconductors have an inverse relationship between temperature coefficient and resistance. When heated, semiconductor conductance increases and resistance decreases. The outermost electrons separate from the material compound’s atomic nucleus. As free electrons multiply, resistance drops accordingly. When manufacturing semiconductors, it is vital to keep temperatures within a certain range so the finished chips perform properly in their application.
Relative humidity in semiconductor cleanrooms should fall between 30-50%. This range is optimal for both inhibiting bacterial growth and the comfort of cleanroom personnel. Airflow should follow vertical laminar flow, where air blows from the ceiling to the floor. The air should enter vents in the floor, be purified by HEPA filters and regulated for temperature and humidity, and then recirculate into the room.
Cleanroom Classifications for Semiconductor Manufacturing
Semiconductor cleanrooms are required to meet ISO 14644-1 Class 5 or lower, which mandates a maximum of 3,520 particles at 0.5µm or smaller per cubic meter of air. They must also comply with ISO 14644-2, which requires the implementation of a quality control system that meets rigorous classification criteria.
Depending on the application, a semiconductor fabrication plant may also have industry-specific regulations from the EPA, the SEMI Standards Program, a variety of industry task forces and technical committees, and other regulatory bodies. There is further variation based on the type of fabrication process, wafer size, and line width. All these standards are followed in conjunction with ISO to ensure the cleanroom environment is under control 24/7 and that the products produced are of consistent and long-lasting quality.
Custom Environmental Control Solutions for Semiconductors
Air Innovations’ custom environmental control units (ECUs) provide precise temperature and humidity tolerances to meet even the most exacting requirements. Minor temperature differences in the environment during semiconductor scanning can result in false readings. Our semiconductor ECUs control for temperature variations within 0.02 °C, resulting in more accurate readings. Other tolerances include the following:
- Airflow: up to 4000 CFM
- Humidity: ± 0.5% relative humidity
- Setpoint temperature: 19 °C – 23 °C
- Temperature change: max of 1°C/5 minutes
- Humidity change: max of 1% relative humidity/3 minutes

Dispatch centers are tasked with receiving communications and initiating appropriate responses. Different agencies and sectors, such as manufacturing, transportation, and law enforcement, use dispatch centers to coordinate and manage operations. Police departments, for instance, use 911 dispatch consoles to respond to calls and establish the proper response needed for each situation.
Since dispatchers spend long hours at these workstations, ergonomics and desk comfort are critical. Comfort and efficiency directly impact performance in these workstations, so the dispatch desk setup, climate control, and surrounding factors must be optimized.
Dispatchers play an important role, so any upgrade that increases their performance is worthy of consideration. Here are some tips on how to make your workspaces more comfortable.
Key Dispatch Desk Features for Creating Optimal Workspaces
Here’s how to design a dispatch workspace for comfort and productivity.
Provide an Ergonomic Chair and Desk
The furniture in the dispatch center greatly determines how comfortable and productive dispatchers will be. Recurring pain due to an uncomfortable chair or desk can lead to distractions, reduced productivity, and even absences from work. Ergonomic workspaces are important because they prevent repetitive motion injuries, lower back pain, fatigue, and other forms of physical discomfort.
Properly Position Office Supplies and Equipment
Office supplies and equipment should be easily accessible to maximize efficiency. You should consider the positioning of items to ensure they are within reach but not so close they cause distraction or cluttering. Paperwork should be organized and quick to access because delays in dispatcher response could mean life or death.
Install Personal Climate Control Systems
Optimal temperature is also crucial for comfort and productivity in dispatch console stations. However, since each person tolerates temperature differently, it may be not ideal to have a “one-temperature fits all” approach in the dispatch center.
Regulating heat and airflow for every workstation is the best solution to keep every dispatcher attentive and comfortable during their long work shifts. Specific solutions include filtered air fans that circulate room temperature air, built-in console fans, and separate standing fans. These personalized solutions also prevent frustrating thermostat wars in the dispatch center and reduce workflow disruptions associated with temperature variations.
Benefits of Having a Personal Climate Control System
Adding personal climate control systems to dispatch console workspaces is an essential step toward enhancing comfort and productivity. Below are some of the advantages of having a personal climate control system.
Optimizes the Workspace
Every office setting has many demographics and people with different climate preferences. Since there is no perfect temperature that fits everyone all of the time, having personal climate control systems is the best way to optimize the workspace and ensure employee satisfaction.
Lowers Costs and Enhances Energy Efficiency
Any agency, business, or institution cares about energy usage and costs. Installing climate control systems in individual spaces can be more efficient and cost-effective than controlling the climate in the entire room or building, particularly when occupancy is lower. In addition, controlling temperature at the individual desk can allow the dispatch center to raise the room temperature in warm months or lower it in cooler months, while still offering end users comfort. These efficiencies help conserve energy and reduce operating expenses.
Ensuring employees are comfortable is a proven way to optimize productivity in a workplace. Reducing distractions and discomfort enables workers to focus on their tasks, which improves output. In addition to an ergonomic chair and desk, an individual climate control system allows dispatchers to customize their environment to their preferences so they can perform their high-stress jobs without additional discomfort.
Reduces the Spread of Airborne Diseases
Central HVAC systems are one of the reasons for the spread of airborne diseases in the workplace. Considering current global health issues, how workplaces limit the spread of airborne diseases is a key concern. Installing climate systems with filtration onboard in individual workspaces can be an effective solution.
Optimizing comfort and productivity does not end with upgrading your dispatch center with ergonomic chairs and desks. The MyZone® desk console management system can help you achieve ultimate comfort in your dispatch workstations. This innovative personal comfort system is designed to boost comfort and productivity, and the device conveniently integrates lift functions, lighting, environmental control, and HEPA filtration within a single unit.

The precise control of air temperature, humidity, particulate levels, pressure and flow rate is critical for the manufacturing and operation of many applications in the semiconductor, aerospace, defense, biomedical and pharmaceutical industries. These are enabled by environmental control systems, which come in various forms and sizes, ranging from relatively small rack-mounted electronic modules to relatively large clean rooms. Because every situation is different, there are very few “plug and play” systems and solutions available on the market that will ideally suit the specific needs of the various applications. This is especially true for first-of-its-kind systems that are being developed to address new or evolving capabilities and technologies. As a result, many of these environmental control systems must be custom engineered. This article reviews some of the challenges of the custom-engineering process, and how Air Innovations can assist customers in developing and optimizing environmental control systems and solutions for their specific applications.
Environmental control system components
Environmental control systems enable the real-time monitoring and control of several environmental variables, such as the level of airborne contaminants, air temperature, humidity, pressure or flow rate. This is usually accomplished with several different components:
Airborne particulates, such as dust, pollen and mold can contaminate the manufacturing process for electronics and pharmaceuticals, or they may disrupt the operation of sensitive electro-optical components. Air cleanliness levels are tested, monitored and controlled according to ISO 14644 standards. High efficiency particulate air (HEPA) filters, which are a type of pleated passive mechanical air filter, remove at least 99.97% of airborne particles with a minimum size of 0.3 microns or greater for the lowest grade HEPA. ULPA (Ultra-Low Particulate Air) remove at least 99.9997% at 0.12 micron or greater. The level of particulate contamination must be measured periodically so the filters can be replaced as needed. Lastly, the amount of clean air that is circulated throughout the enclosure — and how it is distributed — are critical functions of the cleanliness achieved and is a primary focus during the design phase.
Temperature and humidity control
Thermal gradients and moisture in the air may disrupt the operation of sensitive electro-optical components, or result in contamination, such as moisture condensation, water absorption or microbial growth. The control of temperature and humidity typically go together, as the air temperature determines the percent (%RH) of moisture in the air at a given atmospheric pressure. Temperature and humidity control systems require the use of components that are found in standard refrigeration systems, although augmented with highly accurate sensors and control systems, capable of controlling the temperature and humidity within fine limits.
Air pressure and flow control
Environmental control systems clean the air and provide temperature and humidity control by passing or changing the air within the controlled environment several times per hour. It is usually desirable to have a positive (higher) air pressure inside a clean environment so as not to suck in potential contaminants or otherwise un-conditioned air from the external environment through air leaks or open doors. However, in some cases, it may be desirable to create negative or neutral pressure. Air handling units are usually equipped with high capacity fans that can create the desired pressure profile and provide clean, filtered and conditioned outside “make up” air. Air turbulence may also contribute to unwanted thermal gradients or particulate contamination, so many of these air handling units must also be capable of producing laminar air flow within the controlled environment.
Airborne bacteria and molds may contaminate sensitive medical or pharmaceutical manufacturing environments, causing a hazard to consumers. Some environmental control systems that require the flow of sterilized or disinfected air may incorporate ultraviolet germicidal irradiation (UVGI), which is effective in killing or inactivating microorganisms.
An effective environmental control system, regardless of whether it is developed on a relatively small or large scale, must be capable of balancing the control of particulates, temperature, humidity, air pressure and flow rate. A non-optimum system may introduce particulates or contamination into the clean environment, cause wide temperature or humidity swings, create excessive air turbulence or promote the growth of microorganisms. The environmental control system designer must select and implement an optimum set of components to achieve the desired results.
Considerations in environmental control system design process
This section lists a variety of current and future considerations and provides a general “how to” for specifying the design of an environmental control system. While not all of these items may be relevant to the reader’s specific application, they are provided in order to illustrate the potential complexities that may be encountered in the design and development process.
Size and shape of control volume
Does the environmental control system need to be implemented on a certain component, on an entire machine, a manufacturing line or an entire room? Allowance must also be given to the size and placement of the environmental control system components, including fans, filters, heat exchangers, sensors and enclosures.
Equipment and personnel
What are the characteristics of the equipment or personnel operating within the control volume? These may include the following:
- What is the amount of power consumed or generated by internal equipment? (Watts)
- Are there fluids or chemical reactions that generate water or chemical vapors?
- Do moving mechanical assemblies or equipment (such as motors, bearings or slides) create airborne particles?
- Are personnel or equipment from the outside introduced into the control volume?
- Does the internal equipment require open doors during operation?
What is the desired environment within the control volume? This may include the following:
- Atmosphere — Air, nitrogen, inert gas or combustible
- Particulate class (count per unit volume) and size (microns)
- Target temperature (degrees), temperature range (± degrees) and control accuracy (degree change per minute)
- Target humidity (% RH), humidity range (± % RH) and control accuracy (% RH change per minute)
- Air flow rate (volume per minute) and air pressure (wg)
What are the environment extremes in which the controlled volume will operate? These may include the following:
- Presence of excessive dust, dirt, humidity or precipitation
- Ambient temperature range (degrees)
- Ambient humidity range (% RH)
- Operation in direct sunlight (solar heating), corrosive or volatile environments.
These may include the following:
- Explosion-proof components or enclosures
- Ruggedization for operation in high shock or vibration environments
- Microbial control
- Required use of qualified components (e.g., ETL, UL, CSA, CE, CCC, SEMI, MIL-STD)
- Size and shape limitations
These and other requirements are used by the environmental control system designer to develop a system design and conduct trade-off studies. These studies then determine the required air flow rate (cubic feet per minute), the sizing and placement of system components (e.g., fans, heat exchangers, ducts and filters), enclosure and insulation requirements, the placement of sensors, and air flow characteristics (e.g., volume flow rate, laminar versus turbulent flow, once-through versus recirculating air). Prototypes of the environmental control system are then fabricated and tested to verify that it meets or exceeds these requirements.
Air Innovations has worked with many customers in several different industries to overcome unique challenges and develop customized environmental control systems that are optimized to address their requirements. Examples include the following:
A military vehicle application utilized decades-old environmental control technology that fit into a limited space and required upgrading. Air Innovations retrofitted the existing vehicles with upgraded environmental control systems that enabled them to operate in rugged environments over a wider temperature range while allowing the application to fit within its limited space.
A pharmaceutical application required tight temperature and humidity control during the mixing of potentially explosive chemicals and powders. Air Innovations developed an environmental control system using once-through air that was intrinsically safe for explosive environments.
An oil and gas company required equipment to operate over a very wide temperature range (-40° F to 130° F) while maintaining uninterrupted integration with their communications systems. Air Innovations developed an environmental control system that enabled the equipment to continuously operate within a harsh salt and dust environment with high reliability over the required temperature range.
Air Innovations designed, developed and produced an environmental control system for the world’s largest observation wheel, which required a complex-shaped environmental control unit. This system was designed with high reliability, quick serviceability and system redundancy to address potentially life-threatening conditions in the event of power outages or system failure.
Other examples and case studies can be found on the Air Innovations Case Study website.

USP 797 is a standard for sterility that pharmaceutical compounding and preparation facilities must demonstrate. USP 797 is set by the United States Pharmacopeia and National Formulary (USP-NF) and ensures patient safety by protecting pharmaceuticals from contamination during preparation. Following USP 797 reduces infection, contamination, and improper dosage to maintain superior quality products in facilities such as pharmacies, operating rooms, chemotherapy units, hospital pharmacies, and nuclear pharmacies.
Meeting USP 797 Environmental Quality & Control Requirements
Meeting USP 797 standards is critical to the safety of pharmacy environments, as it ensures clean and sterile conditions for compounding and preparing pharmaceutical products. Sterile compounding pharmacy environments and other cleanrooms can demonstrate compliance by following USP 797 standards for monitoring and controlling airborne particles. It is necessary to follow USP 797 to comply with FDA and local regulations, protect against liability, and remain competitive.
- ACPH. Hazardous drug (HD) storage rooms require at least 12 air changes per hour (ACPH) for refrigerated, sterile, and nonsterile storage. Buffer rooms and anterooms with access to HDs require 30 ACPH, and anterooms without HD access require 20 ACPH. Buffer rooms with a redundant HEPA filtration system require 12 ACPH.
- Temperature. Cleanroom temperatures are dependent on the comfort of personnel. It can change relative to the necessary gowning or personal protective equipment (PPE). Sweat and shivering result in more particulate shedding by personnel, so temperatures must not be too low or too high. Uncomfortable temperatures can also encourage staff to shed gowning to cool down or wear unauthorized clothing for warmth.
- Humidity. Clean rooms must maintain an adequate humidity level to prevent personnel from sweating due to high humidity and static buildup in low humidity. Low humidity can also cause residual adhesives from labels to stick to surfaces like gloves. According to USP 797, relative humidity (RH) must be below 60% at all times.
- Pressure. Non-HD compounding pharmacies must maintain positive air pressure to keep airborne particulates, contaminants, and dirt from entering through doors, crevices, and ceiling tiles from outside the cleanroom. HD compounding pharmacies require a negative pressure buffer and positive pressure anteroom to prevent contamination and control HD particles.
- Air quality. Maintaining quality standards requires monitoring of airborne particles. Viable particles require monitoring every week, and non-viable particles require monitoring every six months.
Why Your Central HVAC System Won’t Help You Meet USP 797
Sterile compounding pharmacies within confined spaces often become a hotspot when using a standard building air conditioner that cannot keep up with the humidity. Relying on a standard HVAC system can often times result in a space above USP 797 humidity requirements. Maintaining USP 797 compliance requires an HVAC system designed for pharmaceutical applications. Air Innovations offers HVAC solutions to maintain USP 797 compliance.

Indoor climate control is a wonder of modern engineering, but it can be extremely expensive and wasteful. Nearly 13% of the United State’s energy consumption comes from heating and cooling buildings. Instead of controlling the climate of entire buildings, a better solution may be to control the climate of individual spaces in buildings. Installing a personal climate control system at individual office desks puts each worker in control of their environment while helping businesses save energy and money on utility bills.
Personalized climate control systems in office buildings reduce the amount of heated or cooled air that needs to be supplied throughout the building because only certain areas need cooling at any given time. Cooling vents automatically switch off when a worker leaves their desk, eliminating unnecessary energy consumption. Studies show that providing temperature controls for individual desks can help cut down energy costs by half.
Benefits of Personal Climate Control Systems
Implementing personal climate control systems into workspaces provides a range of benefits to the company and to its employees. Some of the benefits include the following:
Enhanced Energy Efficiency and Reduced Costs
Energy consumption and its costs are a matter of concern for businesses. Personal ventilation systems can help cut costs by enhancing energy efficiency.
Improves Workforce Productivity
The comfort of workers is one of the major factors that improve productivity. People who work for long hours need solutions that enhance comfort. A personal climate control system allows personnel to customize their environment to their comfort level, thereby improving productivity.
Limits Air Borne Diseases Transmission
One of the major causes of the spread of airborne diseases is central HVAC systems. HVAC systems circulate the air throughout the premises, carrying with germs and bacteria with it which results in the spread of various airborne diseases. It has become critically important to limit this spread within facilities given today’s global health situation, and a personal climate control system can be an effective solution.
Nearly 60% of complaints regarding office environment are related to temperature. In any office space, there are diverse people of different sizes and gender with varying climate preferences. There is no perfect temperature to fit the needs of all of them. Providing workers with personal climate control makes it possible to optimize the workspace environment according to individual needs.
