Product Certification

CE compliance starts long before the final certification test. For electronic product development, hardware and PCB design must take applicable EMC, safety, RoHS and other regulatory requirements into account from the beginning. This includes selecting appropriate components, designing protection and filtering, considering creepage and clearance, and maintaining the technical documentation needed to demonstrate conformity.

EMC and FCC compliance should not be treated as the final step of an electronics project. The way a PCB is designed can have a major impact on electromagnetic emissions, signal integrity, product reliability, and ultimately the success of compliance testing. A product may work perfectly during functional testing and still fail EMC or FCC-related tests because of poor grounding, uncontrolled return currents, switching noise, high-speed signal routing, cable placement, or an un
