Hi Sir,

My customer is concerned about the layout for the EMI/EMC issue.

Could you please help to review the schematics and layout file, and also advise some comments with us? Thanks!

Hi,

Do you have the layout file in an Allegro format or do you have a link to a viewer that can open *.ddb?

Thanks

David

Hi,

It looks you are via the signal from the top layer to the bottom layer, do you have GND via placed in equal distance from the signal via?

For your power plane, do you have an adjacent ground plane?

And for TFP401 power, do you have a dedicate power plane or routed it as trace? I would recommend having a plane for the power.

Thanks

David
