Conformal coatings are being used as protection in ever increasing electronic applications across a wide range of market sectors.
In the past, conformal coating was only applied to military and safety critical products like medical devices as the cost and the process of doing this was high.
However, the emphasis on reliability has changed.
In recent years, the development in materials and new processes, linked with the customer requirement of a reliable electronic product that isn’t safety critical, has meant consumer electronics products must now be protected as well.
With the new technologies like wearable electronics becoming more popular then this trend will only increase and protecting the electronics with a coating of some description will become even more commonplace.

So what sectors are using conformal coatings and other thin film technologies?
Due to the fact that conformal coatings provide several key benefits including moisture and insulation properties, chemical resistance and particulate protection, this means they can be used anywhere there is a need for a higher reliability than that which is achieved without the coating.
It is possible to identify both traditional and emerging sectors where conformal coatings are being applied.
These include sectors such as:
- Aerospace
- Defence
- Automotive
- Telecommunications
- Wearable technologies
- Consumer electronics
- Tablets and computers
- Industrial Engineering
- Transport
- White Goods
- Geothermal
- LEDs
- Solar Panels
- Marine and Coastal Environment
- Space
- Medical
Each market sector has a distinct set of requirements in terms of standards, operating environments as well as other factors that impact on the requirements.
The challenge is for the engineer to define the requirements and the suppliers to provide the protection at a commercially effective price.
