Hello guys,
I am designing a 2 layer PCB that contains a power part (PSU, Relays) and digital one (MCU, digital & analog I/Os, ..)...
I looked up some design rules that should minimize EMI but i am not sure if those rules I applied are sufficient for my board to be EMC compliant!!
here are the rules I considered:
what other rules that I could consider to make my board complying with EMC requirement?
How I can know for sure that my board will comply to EMC requirement?
Thanks,

here are the rules I considered:
- Routing signals/pwr on top layer and ground bottom.
- Adding decoupling caps close to ICs.
- using ground plane stitching.
- Avoid long traces on I/O and digital signal lines.
- Avoid putting high-speed circuitry between external mix-signal connectors.
- following layout recomendations for ICs.
- and some obvious layout rules here and there....
