The effect of shielding, grounding and bonding to the electromagnetic compatibility of high emission printed circuit board
Electromagnetic Compatibility (EMC) is the capability of the device or the system to perform its work correctly within its electromagnetic environment without causing the introduction of electromagnetic damage to that environment. Radiated Emission (RE) is one of the EMC tests that should be conduct...

Electromagnetic Compatibility (EMC) is the capability of the device or the system to perform its work correctly within its electromagnetic environment without causing the introduction of electromagnetic damage to that environment.
