About CIEMS
In the field of materials and devices testing, CIEMS is basically oriented toward measuring electrical, magnetic, thermal and optical properties of solid and liquid metallic, semiconducting and insulating materials, and testing electronic instruments and various elements of the electronic and electrical equipment.
Having originated in the area of the "Electronics Belt" of Boston, CIEMS moved in 1981 to California, and very soon after the beginning of its operations in the Golden State, a wide range of businesses, industries, professional and government agencies all over the USA - from Washington to Florida and from Maine to Arizona - were attracted by the high efficiency, reliability and accuracy of the testing methods and equipment used by CIEMS in combination with very reasonable charges for its services.
A relatively narrow specialization of testing - only electrical, thermal and optical methods - permits the scientists and engineers of CIEMS to concentrate on excellence of performance, on improvement of measurement accuracy, and on the reliability of test results. Normally, we use testing methods and calibrated apparatuses in accordance with the guidelines of the American Society for Testing and Materials, American National Standard Institute, American Society for Quality Institute of Electronic and Electrical Engineers, National Electrical Testing Association, and National Institute of Standards and Technology (National Bureau of Standards). In cases where there is not a standard procedure, we design and implement special testing methods to meet the needs of our clients.
The CIEMS' staff of engineers, scientists, and technicians possess top credentials and long years of hands-on experience. They have knowledge and resources to test virtually any material, instrument, or device that is used in industry. Our key specialists are active members of the leading standard-making societies. The CIEMS test reports routinely provide not only exhaustive information regarding the test results and detailed description of the test equipment and methods used, but also data that enable clients to improve their products.
