Spraying conformal coating on a circuit board is an essential step in protecting electronic components from harsh environments. However, even experienced professionals can make mistakes during the process, resulting in significant damage to the circuit board.

Conformal coatings are thin-layer polymers that are applied to the surface of printed circuit boards (PCBs), with typical thickness between 25μm to 150μ, to protect and electrically insulate the circuits and board components from environmental stresses.

Modern PCBs are smaller and more densely populated with sensitive components than ever before, especially in demanding industries such as automotive and aerospace.

Hybrid Light-Curable technology is a patent-pending adhesive platform combining the best qualities of anionic and free radical chemistries into one revolutionary formulation.

A basic definition of a conformal coating is a coating, which is applied to the PCB surface and “conforms” to the various irregularities and contours of components at an even and consistent thickness.
