Hi team

In the app note, conformal coating can help reduce the requirement for creepage and clearance by reducing the pollution degree under the coating, as well as blocking the path for arcing between pins.

So could you tell example of coatign agent? They want to understand it as references.

Hi Takahashi-san,

Thanks for reaching out.

Conformal coating is typically a polymeric layer that is coated on the PCB. there are several types of conformal coatings and choosing the type typically depends on the customer application. I will check with my team if there is a specific conformal coating that is recommended.

Hi Takahashi-san,

I was able to get some clarification from my team.

We do not have examples of conformal coating since we do not evaluate conformal coating for our devices.
