Conformal Coating

What is Conformal Coating? What purpose does it serve?

 

Conformal Coating is a spray or drip coating used to cover a populated printed circuit board to protect it from the elements. Think of it like a spray on lacquer used on furniture.

Conformal coated electronics assemblies often have a shiny appearance on component and printed circuit board (PCB) surfaces. It’s possible to conformal coat only portions of a PCB.

Conformal Coating Case Study

Protecting Your Electronics with Conformal Coating

 

The PCBA shown here is an industrial lighting controller used in outdoor environments where high humidity, salt spray, and particulate may be present.

Conformal coating in this instance protects the circuit nodes from shorting to each other by providing a thin dielectric layer.

The blue cap on the upper right image, and the small yellow piece on the upper left image, both act as masking to keep these areas free of conformal coating during application. These are applied prior to conformal coat application and removed after.

Most products do not require conformal coating.
