What is a conformal coating and can I protect my circuit board with the material?
A conformal coating is a protective non conductive dielectric layer that is applied onto the printed circuit board assembly to protect the electronic assembly from damage due to contamination, salt spray, moisture, fungus, dust and corrosion caused by harsh or extreme environments.It is normally used on electronic circuit boards that are exposed to adverse environments where heat, chemicals and / or moisture are prevalent.
Coating also can prevent damage from rough handling, installation, reduction of mechanical and thermal stress. It can prolong the life of the product during its operation and at the same time it can help to increase the dielectric strength between conductors enabling the design of the PCB to be more compact and small. Finally, it also acts to protect circuitry and components from abrasion and solvents.
MG Chemicals have a range of conformal coatings which will protect a circuit board from corrosive effects. These conformal coating materials can be applied by spray, dip, brush or robotic selective application methods.
