Humidity Control for the Electronics Industry: Comprehensive Solutions with DeAir Equipment

Vietnam, characterized by its tropical monsoon climate, frequently experiences high humidity levels, often above 80%. These weather conditions pose significant challenges for manufacturing and product preservation, especially in the sensitive electronics industry. In an environment where every small component can be affected by even minor environmental changes, humidity control isn't just a technical requirement; it's a vital factor determining quality and production efficiency.

Industrial humidity control equipment consists of specialized systems designed to maintain air humidity levels in production areas, warehouses, and clean rooms at a specific target value. DeAir, with its extensive experience and specialized capabilities, offers comprehensive humidity treatment solutions, helping electronics businesses control their environment, protect assets, and enhance business efficiency.

Why Does the Electronics Industry Need Strict Humidity Control?

Electronic components are the backbone of modern technology, and they are highly sensitive to temperature and humidity. Uncontrolled humidity can cause significant damage:

• Decreased quality of components and products: High humidity can cause electronic components to rust, warp, or even short-circuit. Moisture can condense, leading to short circuits, corrosion of circuit boards, or device failures during testing. Moisture ingress also causes corrosion and destruction of electronic materials. High humidity also accelerates material degradation, such as corrosion of metal connections. Conversely, excessively low humidity can make materials brittle, prone to cracking, and pose many risks, especially in electronics manufacturing environments.
• Causes electrostatic discharge (ESD): When humidity drops below 30% RH, the air becomes dry and conducts electricity more readily, leading to electrostatic discharge (ESD). Even tiny ESD events are enough to completely damage an active microchip or circuit board. Low humidity also increases the ability to transmit static electricity.
• Affects production processes: Inappropriate humidity reduces the operational efficiency of machinery and equipment. The presence of moisture prevents materials from bonding effectively, for example, moisture-sensitive adhesives or coatings can peel off or have reduced bond strength.
• Damage to machinery and equipment: Moisture causes corrosion and rust to metal parts, damages electronic circuit boards, and reduces the lifespan of production and packaging equipment. High humidity causes air filtration systems, air conditioners, or industrial dehumidifiers to overwork, increasing maintenance and operating costs. Unstable humidity also causes equipment to degrade quickly.
• Compromises safety and affects worker health: Humid environments easily lead to slips and falls, creating conditions for mold and bacteria to grow, increasing the risk of respiratory diseases and allergies. Conversely, dry environments (too low humidity) cause dry skin, tired eyes, nasal inflammation, or respiratory irritation. Maintaining a safe humidity level helps workers feel comfortable and increases productivity.
• Regulatory compliance: The electronics industry has strict standards for microclimate conditions (temperature, humidity) that must be complied with. International standards like ISO 14644 are closely related to humidity control in clean rooms.

Ideal Humidity Levels in Electronics Factories

There isn't a "fixed" humidity level that applies to all areas within an electronics factory. Specific humidity requirements will vary depending on each stage of component manufacturing and storage.

• Chip and semiconductor manufacturing areas: These areas require extremely low humidity, typically below 40% RH, and can even go down to 1% RH or lower to prevent oxidation, corrosion, and especially the "popcorning" effect during heating. Higher-grade clean rooms (such as Class 100, Class 1000) require even more precise humidity control, usually ranging between 30 – 40% RH.
• General electronics component manufacturing areas: Typically maintain humidity levels at 30 – 45% RH to avoid static charge buildup. The 30 – 40% RH range is considered optimal in most sensitive clean rooms, such as those for electronics, due to the ideal balance between static control and limiting microbial growth.

Clearly defining each humidity "zone" allows for the design of a more flexible, efficient, and cost-effective industrial dehumidification system.

Comprehensive Humidity Control Solutions from DeAir for the Electronics Industry

An effective dehumidification solution for factories in the electronics industry involves the synchronous integration of various technologies. DeAir provides comprehensive equipment and solutions to meet these stringent requirements.

1. Industrial Dehumidifiers: Their main function is to reduce humidity in the air. For the electronics industry, especially areas requiring extremely low humidity:

   • Rotor (adsorption) Dezenno dehumidifier: This is the optimal choice for achieving the ultra-low humidity levels required in the electronics industry. Rotor technology uses desiccant materials (usually silica gel) to absorb moisture, operating effectively even at low temperatures and humidity, capable of achieving very low humidity. Dezenno rotor dehumidification equipment from DeAir is manufactured to European standards in Vietnam, specifically designed to control both absolute and relative humidity down to very low dew points. Dezenno machines feature double-walled insulation, light weight, can withstand harsh operating conditions, and use the highest quality desiccant rotors. They can control airflow infinitely with a frequency converter, helping to save electricity.

   • Heat-Pump DeAir dehumidifier: DeAir applies energy-saving Heat Pump technology in its industrial humidity treatment solutions. This technology outperforms conventional condensing machines by reusing heat, significantly saving electricity and maintaining stable dehumidification performance even at low ambient temperatures. DeAir's Heat-Pump models include:

     • DeAir.RE (Floor-standing): Suitable for various spaces, from residential to industrial, prioritizing dehumidification efficiency and power savings. Available in models with diverse dehumidification capacities (60 kg/day to 1200 kg/day).
     • DeAir.RE-H (Heat-Pump Drying): Capable of operating at higher temperatures, suitable for applications requiring dehumidification in relatively high-temperature conditions or combined with drying.
     • DeAir.RE-INOX (Stainless Steel Casing): Similar to RE-H but with a stainless steel casing, increasing durability and suitability for environments requiring high hygiene or with corrosive properties, such as in industries with high cleanliness requirements.
     • DeAir.RE-CL (Ceiling-mounted): Ceiling-mounted design saves floor space, suitable for areas requiring optimized space such as factories, warehouses, and laboratories.
     • DeAir.CRE (Isothermal): Stands out with its ability to precisely control both humidity and temperature simultaneously. This is the biggest difference, crucial in special applications like laboratories, museums, or production processes sensitive to temperature changes.

   • Olmas industrial dehumidifier: Uses condensing technology, suitable for medium-scale production environments with temperatures ranging from 15°C - 40°C. Can be applied in storage warehouses, food and pharmaceutical factories, precision machining workshops, museums, and exhibition halls. (Note: Condensing technology's efficiency decreases at low temperatures and struggles to achieve extremely low humidity like Rotor technology).

2. Industrial Humidifier Equipment: Its main function is to increase humidity in the air when the environment is too dry. Although the electronics industry primarily needs dehumidification, humidity control sometimes requires adding moisture if the environment becomes too dry (below 30% RH) to prevent electrostatic discharge (ESD) and health issues for employees.

   • DeAir.HM humidifier: DeAir offers the DeAir.HM humidifier series with various technologies such as spray, evaporative, ultrasonic, and electrode, depending on application requirements.
