As of today, conformal coating applications have not yet achieved a wide diffusion and many of the features that belong to this process are disregarded, misunderstood or even completely ignored by a multitude of companies that could otherwise benefit from them.
In fact, anyone who use industrial electronics inside their products, or inside their processes, could be enjoying a wide array of benefits from conformal coating. Some examples? Here they are:
Of course, these benefits will only arise if conformal coating is done effectively, with proper know-how and proper equipment.
Alongside any technical detail, which is domain of experts only, there are a few simpler and very useful information that any interested party should have when it comes to conformal coating.
In this article, we'll cover the five most essential pieces of knowledge.
Conformal coating is nearly always associated with the product it gives the name to. But are we sure this is the correct way to intend it? We think it's not. Conformal coating is first and foremost a production process that is conducted when the cooperation of the following elements occure:
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:
The most conventional methods of application are the following:
Each and every method has its own strengths and the choice of which one is best suited for a specific product is very case sensitive. In CTA Electronics, we can count on a proper production department entirely equipped for conformal coating, which allows us to execute the selective roboting coating as well as any other kind of application.
The primary reason why there are many different kinds of conformal coating resides in the fact that every polymer has its own defining feature. Simplifying, we can say there are mainly four product families:
Improper tools or unexperienced resources may cause productive damages that are very likely to discard the benefits of the coating application. Elements like:
Must be carefully measured upon the very specifical needs of each and every production batch, and the entire process must be managed skillfully and proactively.
Conformal Coating is, by all means, a very interesting application for the industrial electronic industry and is a complementary process that is able to add value to the production of electronic boards, circuits and complete products. However, in order to be successful and valuable, this process must be handled upon a firm know-how and should be executed only by companies with a solid base in terms of knowledge, experience and possession of professional equipment.
