Hello everyone! Thanks for your comments on my questions below!
1.) The best case for shielding is a fully enclosed metal box. Would this be equivalent to a shield on one side of the PCB with a ground plane on the opposite side of the PCB?2.) What is the best approach when you have a break in your metal shielding for connectors? Should I bring the shielding all the way around the connector? If I do this how should I route the lines? Under the shielding with a via? Or through the shielding? Or just keep the gap open for the connector?
3.) We had big ferrite clamps that we put on the signal cables and power supply. I would not like to have these large clamps on the cable and fix things inside of the device. The largest bandwidth for our signals is 500 Hz. We were seeing problems above 30 MHz for our emissions testing with the cables. Would it make sense to filter the signals going out on the cables? Or is there a bead that is small that would do the trick inside of the device?Thanks in advance for your comments!
