Hello everyone! Thanks for your comments on my questions below!
1.) The best case for ****elding is a fully enclosed metal box. Would
this be equivalent to a ****eld 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
****elding for connectors? Should I bring the ****elding all the way
around the connector? If I do this how should I route the lines?
Under the ****elding with a via? Or through the ****elding? 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!
