    EMC testing

    Background of the project:
    In order to prevent electromagnetic interference generated by some electronic products, affecting or destroying the normal operation of other electronic devices, governments or some international organizations have proposed or formulated some regulations or standards related to electromagnetic interference of electronic products, in compliance with these regulations or standards. The product can be called EMC (Electromagnetic Compatibility).

    The test has strong electromagnetic compatibility testing capability, and has established good cooperative relations with many international certification bodies. It can provide high-quality testing services, help customers solve electromagnetic compatibility problems in product development and design process, and propose electromagnetic compatibility solutions for products. Program.

    service items:
    The test can be based on customer needs, to develop a detailed and reasonable electromagnetic compatibility test program, to guide customers to quickly confirm the test objectives, to provide customers with one-stop integrated services, specific services include (not limited to) the following:
    Conduct electromagnetic compatibility testing and evaluation of products according to standards, and provide test reports;
    Assist customers to apply for and obtain CE, FCC, E/e-Mark, VCCI, CCC and other product certifications;
    Instruct customers to deeply understand electromagnetic compatibility related regulations and standards and improve compliance rates.
    Cooperate with the customer site to complete the test and meet the customer's various parameters.
