Electronic gadgets are governed by regulations concerning electrical safety, electromagnetic noise immunity, and electromagnetic noise radiation. Stricter regulations apply to electronic equipment attached to public telecommunications networks to ensure the equipment is harmless to the network or to people working on it. A compliance engineer is the professional who evaluates and performs a series of tests to gain sufficient assurance that the prescribed internal controls of an electronic product are operating effectively within these defined limits.
As the famous saying goes, ''If you don’t know where you’re going, all roads lead there.'' Any serious study of EMC requires a sound understanding of several aspects of electrical engineering. In a field as diverse as EMC, in which the intricacies of practical problems are significant, it may not always be possible for a compliance engineer to provide complete and accurate answers. In such cases, it is crucial that the compliance engineer establishes and grasps the underlying nature of electrical products, their interactions with electromagnetic fields, and the nature of electrical signals.
The roadmap to becoming a world-class compliance engineer involves a simple three-pronged strategy: (1) defining or adopting a superlative testing model, (2) determining your existing testing capabilities, competencies, and user satisfaction, and (3) developing and implementing a plan to upgrade your own skills to match those in the testing model.
Compliance testing necessitates that the prepared documents be compared to prescribed standards concerning EMC requirements, including EMC compliance testing, EMR surveys, EMC Test System Integration, and RF Shielded Enclosures. As with any aspects of electromagnetic compatibility, problems can and will happen during testing and the debugging phase. To minimize problems, the compliance engineer must be fully aware of the equipment setup and environment, and take suitable action as required.
The most effective method for compliance engineering testing is the inspection process. The types of tests conducted in this process vary based on the phase of the development life cycle. However, it is much more important to test adherence to the process and regulations during the requirement phase than at penultimate stages because it becomes increasingly difficult to correct any problems when specifications have not been sufficiently documented.
Thorough compliance engineering vis-a-vis a requirement document can be quite an arduous and time-consuming task depending on how the requirements are written, and how complex the described interactions turn out to be. Earlier compliance testing and documentation was often outsourced and managed by external resources, which prevented process owners from fully acknowledging ownership of the control environment. The compliance engineer drives greater internal resource involvement and encourages greater awareness through continuous training as well as documentation and testing approval.
