Proper implementation can mean the difference between an electronic product that functions perfectly for years or one that fails prematurely due to undetected moisture damage.

This comprehensive guide takes an in-depth look at the world of humidity indicators in the electronics industry: from their operating principles and available types to the international standards governing their use and best practices for effective implementation. Whether you work in component manufacturing, PCB assembly, electronics warehousing, or supply chain management, this information will help you protect your products against one of the greatest risks to the integrity of electronic devices.

Fundamentals of Humidity Indicators and Their Importance in Electronics

Humidity indicators, also known as HICs (Humidity Indicator Cards), are passive monitoring devices that provide visual information about the relative humidity levels to which electronic components or products have been exposed. They operate based on simple yet effective chemical principles that allow them to detect potentially harmful conditions before they cause irreversible problems.

Principles of Operation and Composition

Humidity indicators work by a visible color change that occurs when a certain level of relative humidity is reached in the environment:

Chemical composition

They contain moisture-sensitive chemical compounds, traditionally cobalt salts (although cobalt-free versions exist)
The chemical compound is impregnated into a paper or plastic substrate
The chemical reaction that produces the color change is generally reversible in standard indicators.

Color change mechanism

In traditional indicators with cobalt: change from blue (dry) to pink (wet)
In cobalt-free indicators: various color changes depending on the manufacturer (blue to white, yellow to green, etc.)
Changes occur at specific points that represent different levels of relative humidity.

Types of reaction

Reversible: They change color when humidity increases and return to their original color when it decreases.
Non-reversible: Once they change color due to exposure to moisture, they maintain that change permanently, providing a historical record of exposure.

The accuracy of these gauges is calibrated to detect specific levels of relative humidity, typically in ranges from 5% to 60% RH, depending on the gauge type and its specific application.

Why Humidity Is an Enemy of Electronic Components

Humidity represents one of the greatest risks to the integrity and operation of electronic components for several reasons:

Physical damage during thermal processes

Popcorn effect: When components that have absorbed moisture are subjected to high temperatures (such as in reflow soldering), the moisture quickly turns to vapor, expanding and causing delamination or cracking of the package.
Layer separation: In multilayer PCBs, moisture can cause separation between layers during thermal processes.
Fracture of internal connections: Steam expansion can break wire connections or solders inside encapsulated components.

Chemical and electrical degradation

Corrosion: Humidity accelerates the oxidation of metal contacts and conductive tracks.
Electrochemical migration: In the presence of moisture, metal ions can migrate between nearby conductors, forming dendrites that eventually cause short circuits.
Degradation of insulators: Many insulating materials lose their dielectric properties when they absorb moisture.
Current leaks: Moisture can create conduction paths between points that should be insulated.

Long-term effects

Reduction of useful life: Even moderate levels of humidity can accelerate the aging of components.
Intermittent failures: Humidity can cause erratic behavior that is difficult to diagnose.
Progressive degradation: Moisture damage is often cumulative and can manifest long after initial exposure.

Costs Associated with Moisture Damage

The economic impact of not properly controlling humidity in electronic components can be substantial:

Direct costs

Loss of components and materials
Reprocessing and repair time
Production delays
Increase in testing and quality control

Indirect costs

Field failures and product returns
Damage to the brand's reputation
Possible legal liabilities
Loss of customer confidence

Industry studies have estimated that between 10% and 15% of electronic product failures can be directly or indirectly attributed to moisture-related problems, representing billions of dollars in annual losses globally.

Critical Applications of Humidity Indicators

Humidity indicators are particularly important in certain contexts within the electronics industry:
