Conformal Coating And Potting

Protecting Your Electronics

Conformal Coating vs Potting
We recognize the importance of protecting electronic components and Printed Circuit Board Assemblies (PCBAs) from environmental factors such as moisture, dust, chemicals, and temperature variations. Hence, we offer two key services: Conformal Coating and Potting. But what are these processes, and how do they differ?

Conformal Coating
Conformal Coating is a non-conductive dielectric layer applied to a circuit board or electronic device. The coating “conforms” to the object being coated, often referred to as the “substrate,” allowing protection without significant additions to the weight or thickness of the device. It’s typically a thin layer (25 to 250 micrometers thick) that provides electrical insulation as well as thermal and chemical resistance.

This method is often preferred for devices with strict weight or thickness restrictions, as it provides high protection without adding significant bulk.

Potting
Potting, however, involves encasing the entire electronic assembly within a “pot” or shell, filled with a solid or gelatinous compound. This process provides a higher level of protection, especially against impact, vibration, and harsh environmental conditions.

Potting can also offer significant vibration dampening, heat dissipation, and can even obscure the circuit board or device for privacy and security. This method is chosen for devices that need to withstand potential impact damage or rough mechanical abrasion.

Which One is Right for You?
The choice between conformal coating and potting depends on the specific requirements of your device, such as the degree of protection needed, the construction of the device, and the conditions under which it will operate.

At ANZ ELECTRIC, our team of experts can guide you through the decision-making process, ensuring that your electronics are protected in the most effective way possible.
