What exactly is conformal coating?
Conformal coating is nearly always associated with the product it gives the name to. But in reality, conformal coating is first and foremost a production process that is carried out when the cooperation of the following elements:
- Specific equipment and specific machinery
- Properly trained personnel
- Polymers with precise features
These polymers are commonly called Conformal Coating because, as a matter of fact, they represent the substances used to coat the printed circuits in order to make them conformal. What do they need to conform to? Well, they conform to needs of various kinds, sometimes purely technical, sometimes functional and sometimes even regulatory.
The primary scope of conformal coating is the protection of the printed circuits and of the components that are mounted on them. The coating protects from a wide range of elements, among which the most common are:
- Environmental infiltration
- Chemical agents
- Extreme Temperatures
The protection assured by the coating provides prevention of damages caused by corrosion, moulding, infiltrations and electric deficiency.
