Look around. It’s no secret that electronics have become an integral part of the human experience. From smartphones and automobiles to medical devices and exercise equipment, each device serves a vastly different purpose in our lives. Still, they share one similarity—they are all equipped with some electronic circuitry. These circuits are usually designed on a rigid or flexible printed circuit board (PCB)and integrated into various electronic devices. However, because of how electronic devices are used, they are especially susceptible to failure if exposed to contaminants such as dust particles, moisture, humidity, corrosive substances, and other foreign materials. Manufacturers and consumers both want the same thing: they want their products to last. In order to extend a product’s lifecycle, it is essential that its PCB must be well protected from exposure. Enter the conformal coating.
