Whilst it is tempting to choose your coating based on cost factors, it is important to remember that to achieve the right level of protection from your coating material you will need to carefully select the right material for your application. Conformal Coating Selection and Best Practice: However due to the rapid expansion of the electronics industry, conformal coatings are also finding their way into the domestic and mobile electronics industries, providing the necessary combination of high performance and reliability within a vast array of electronic devices. The use of conformal coatings is particularly important in automotive, military, aerospace, marine, lighting, industrial and green energy applications. Which industry requires Conformal Coatings? The protection provided by conformal coatings allows for higher voltage gradients and closer track spacing, in turn enabling designers to meet the demands of miniaturisation and reliability. Conformal coatings can be used in a wide range of environments to protect printed circuit boards from moisture, salt spray, chemicals and temperature extremes in order to prevent such things as corrosion, mould growth and electrical failures. Why do I need a Conformal Coating?Ī newly manufactured printed circuit board will generally perform well, but performance can quickly deteriorate due to external factors in its operating environment. The film is typically applied at 25-250µm and ‘conforms’ to the shape of the board and its components, covering and protecting solder joints, the leads of electronic components, exposed traces, and other metallised areas from corrosion, ultimately extending the working life of the PCB. What Are Conformal Coatings? Everything you need to know: What Are Conformal Coatings?Ī conformal coating is a thin polymeric film applied to a printed circuit board (PCB) in order to protect the board and its components from the environment and corrosion.
