How Does the Ozone Corrode Circuits?
The ozone layer is a powerful, protective barrier around the Earth, but as it’s begun to break down over time, more and more harmful effects are being realized down below. While the ozone itself does not corrode circuits, there are many ozone corroding gases that can affect the performance and longevity of circuit boards and other technological components. Learn how to protect your circuits with ozone-resistant materials from Gateway Cable Company.
What is the Ozone?
The ozone layer, or ozone, is a protective shield of gases encircling the Earth. Located in the lower stratosphere, this concentration of ozone helps absorb up to 99% of the sun’s ultraviolet light; without the ozone, life forms on Earth would see serious harm and deterioration.
In the late 1970s, scientists discovered that certain chemicals being released into the air were having a detrimental effect on the ozone layer, effectively breaking down the protective barrier. Chlorofluorocarbons proved to be one of the main ozone corroding gases, and legislation was passed to ban use of these chemicals.
Despite these efforts, the ozone layer has continued to decline, with some parts of the planet experiencing “ozone holes” where there is significant degradation. This is a tangible example of climate change.
Ozone Gases That Corrode Circuits
There are many environmental factors that can lead to corroded circuits, including humidity, temperature, and pollutants. Of the three, gaseous pollutants have the most destructive effects, as their chemical makeup can clash and counteract against certain metals and technological parts.
The most prevalent ozone gases that corrode circuits are:
- Sulfur dioxide (SO2)
- Ozone (O3)
- Nitrogen dioxide (NO2)
- Chlorides (Chlorine [Cl2] and Hydrogen chloride [HCl])
- Acetic acid (CH3COOH)
- Formaldehyde (HCHO)
When these chemicals come in contact with circuit boards, they can create corrosion and oxidation, limiting the performance of your tech.
How to Protect Against Ozone Corroding Gases
Protecting property against harmful environmental factors is always a challenge. In certain situations it may prove impossible to guarantee complete protection, but there are ways to safeguard against ozone gases that corrode circuits:
- Keep your circuits in cool or temperature-moderated conditions. Use a shield or cover to protect against the elements.
- Apply ozone-resistant protective coating such as epoxy or silicone as an added barrier.
- Use heat insulating materials that are designed to distribute heat in a regulated manner.
