Conformal Coating

Conformal Coating

What is Conformal Coating? 

Conformal coating is a protective, breathable coating of thin polymeric film applied to printed circuit boards. Conformal coating is typically applied at 20-25μm thickness, and designed to protect against moisture and other harsher conditions. Conformal Coating is now considered standard practice in PCB assembly and is applicable across a wide array of different industries.

How is Conformal Coating applied?

There are several different ways that you can apply conformal coatings, including dip coating, brushing, spraying, and dispensing. A variety of different materials can be used, such as perylene, silicones, urethanes, and acrylics. Each method and material has it's own characteristics for different purposes. The conformal coatings contain a fluorescent dye which although is unclear to the naked eye, becomes visible under Ultraviolet lighting. This not only helps our specially trained technicians apply as per the engineering drawings but also helps to aid in coating coverage inspection.

What are the advantages of Conformal Coating?

Conformal Coatings can prevent problems with printed circuit boards such as the ingress of dirt, moisture, dust, can help to protect your PCB against rust, abrasion, chemical damage, mechanical stress, and vibration. All of this helps to extend the life of your product, and reduce failure rates.
