The coating is named conformal since it conforms to the contours of the PCB. Conformal coatings are typically applied at 25-250 μm to the electronic circuitry and provides protection against moisture, dust, chemicals and temperature extremities.

IPC-A-610: This is the acceptability of electronics assemblies standard. It covers many aspects of PCB manufacturing, including the requirements for coating thickness ing to their material and the function of the components being covered.

Conformal coating is a thin film of protective material applied to a circuit board after it has been fully assembled. It is a non-conductive dielectric material that will protect the board and its components from salt-spray, moisture, fungus, dust, and other contaminants that can cause corrosion of exposed metal.

[3] Physical appearance can be easily verified by visual inspection. Magnification may be used up to 4X.

The IPC standard states that, in general, conformal coatings should be transparent, have a uniform colour and consistency, and cover the board and components uniformly. The coating coverage will depend on the application method. From this there is much to infer, which can cause problems if interpreted incorrectly.

This coating is a thin non-conductive dielectric film that can be brushed on, sprayed on, or applied by automated processes that include spraying or dipping. It is designed to protect the components of a circuit board as well as solder joints, and other exposed areas of metal.

The IPC A 610 standard defines ideal liquid conformal coating thickness values as: Acrylic: 30-130μm. Polyurethane: 30-130μm. Silicone: 50-210μm.

IPC-CC-830 - Revision C - Standard Only. Qualification and Performance of Electrical Insulating Compound for Printed Wiring Assemblies. The IPC-CC-830C standard establishes qualification and conformance requirements for electrical insulating compounds (conformal coatings).
