1.What is a Conformal Coating?

Conformal coating is a protective and non conductive coating that is applied onto the printed circuit board. This protects the electronic assembly from damage that may be due to contamination, salt spray, moisture, fungus, dust and corrosion caused by harsh environments.

3.What are the advantages of using a conformal coating?

Insulating properties can allow a reduction in PCB conductor spacing;
Can help eliminate the need for complex, sophisticated enclosures;
Provide extended service life by:
1)Protecting against humidity, chemical, and physical attack
2)Protecting against thermal variations and shocks
3)Protecting against vibration and mechanical shocks

4.How does conformal coating work?

Conformal coating is a barrier that protects electronic components against harsh environments.
They are a breathable protective layer that allows moisture trapped in the circuit board to escape.
The material tends to be lightweight and helps to increase the strength between conductors which enables the PCB to be small and compact.

5.What is the process of conformal coating?

Step1:Make sure the board is cleaned
Step2:Remove all protected areas such as terminal pins and connectors
Step3:Apply the conformal coating
Step4:Cure the coating (this differs according to the coating type)
Step5:Reassemble any removed parts
Step6:Undergo a full test to ensure the functionality of board has not been affected.
