How do you ensure your circuits perform up to spec in the real world? Conformal coatings! These thin, protective layers act like a shield, safeguarding your circuits from the potentially harsh conditions of the world. From moisture and dust to temperature swings and chemicals, conformal coatings keep your electronics running smoothly.
While many different types of conformal coatings exist, each provides critical protection, helping circuits last for years. Here are some of the benefits of conformal coatings.
1. Protection from Environmental Conditions
If the circuit will be deployed in harsh conditions such as high humidity, extreme temperatures cycling, or exposure to chemicals, conformal coating helps ensure the longevity and reliability of the electronic components. Different conformal coatings offer different levels of protection for things like:
- UV exposure
- Chemical exposure and corrosion
- Extreme temperatures
- Mechanical stress
2. Cost Considerations
While circuits with conformal coating may have a slightly higher upfront cost, they can result in long-term cost savings by minimizing repairs or replacements. The incremental cost of a conformal coating up front is often far less than the cost of replacement or repair, especially when considering product downtime.
3. Compliance and Standards
Many industries, such as aerospace, automotive, and medical devices, establish standards to help ensure the reliability of electronics. Many of these standards, such as IPC-A-610, establish guidelines for the application of conformal coatings in order to ensure quality, safety, and reliability.
There are many types of conformal coatings available, ranging in price and protective qualities. The chart below provides an overview of what protections each type of conformal coating offers.
