What Causes Chemical Failures in Electronics?
Chemical failures in electronics are typically the result of interactions between materials and their environment. These interactions can lead to the deterioration of components, ultimately causing system malfunctions. Here, we'll explore the three primary causes of chemical failures: corrosion, contamination, and outgassing.
1. Corrosion
Corrosion occurs when metal components, such as connectors, solder joints, or conductive traces, are exposed to moisture and chemicals. This exposure leads to chemical reactions that degrade the metal, forming oxides or other corrosive compounds. Over time, this degradation can compromise the integrity of the components, leading to electrical failures.
- Moisture Exposure: High humidity or direct exposure to water can accelerate the corrosion process, especially in environments where electronics are subject to moisture ingress.
- Chemical Exposure: Exposure to certain chemicals, including industrial pollutants or cleaning agents, can exacerbate corrosion, particularly on unprotected metal surfaces.
2. Contamination
Contamination is another significant cause of chemical failures in electronics. Contaminants can originate from manufacturing processes, such as flux residues, or from environmental exposure, like dust and airborne chemicals. These residues can lead to unwanted chemical reactions, compromising the performance of electronic components.
- Manufacturing Residues: Residues left on PCBs after soldering, such as flux, can attract moisture, leading to corrosion or electrochemical migration, which can cause short circuits.
- Environmental Contaminants: Dust, oils, or other airborne particles can settle on electronic components, leading to similar degradation or failure over time.
3. Outgassing
Outgassing refers to the release of gases from materials used in electronic components. Over time, certain materials can emit volatile compounds, which may condense on nearby components. This condensation can form a conductive or corrosive layer, leading to failures, particularly in sensitive areas like connectors or optical surfaces.
- Material Degradation: Some plastics, adhesives, or coatings can outgas over time, especially under elevated temperatures or in vacuum conditions.
- Component Contamination: Outgassed materials can deposit on critical components, leading to increased resistance, signal loss, or short circuits.
