【Test items】

      Battery Level Monitoring: Analyze your phone's behavior, find programs that cause the battery to run out of battery, and take the appropriate action. In simple terms, it is software that can extend battery life.

      Thermal cycling test: used in electronic products or plastic parts, etc., susceptible to ambient temperature or product operating temperature of the product. In the new product design and development stage, a certain number of test items, after thermal cycling test, used to understand the future of the product by the temperature changes after the weaknesses in order to design quality or the use of material quality improvement.

       Insulation withstand voltage tester: According to the latest national power industry standard design of intelligent pressure test equipment, for a variety of electrical products, electrical components, insulation materials, such as the provisions of the voltage under the insulation strength test to assess the insulation products Level, found that the test object insulation defects, the ability to measure overvoltage. Widely used in electrical manufacturing sector, power operation departments, scientific research units and institutions of higher learning.

       Environmental testing: refers to the systematic use of biological reactions to determine one or more pollutants or environmental factors alone or in combination, the resulting impact or harm. Also used for electronic equipment anti-jamming capability of the test, such as EMC (including EMI, EMS) test.

       Electromagnetic compatibility testing: including test methods, measuring instruments and test sites, test methods based on various standards, measuring instruments based on the frequency domain, the test site is a prerequisite for EMC testing, EMC is also an important factor in measuring the level of work The EMC testing is greatly influenced by the site, especially with electromagnetic radiation, radiation and radiation sensitivity of the test site requirements of the most stringent.

       Durability test: the length of service life of new products related to product design, manufacturing, materials, processes, manufacturing process quality management and user maintenance level and other conditions. Therefore, in the development of new products to develop stereotypes or production processes, materials have significant changes, to carry out product durability test, the test time is generally longer than the reliability test, through the durability test to find the reliability of the product in order to improve the design or improve the process Level, at the same time by testing the product of the wear, calculate the service life.

       Material testing: raw material composition analysis, measurement, no damage detection and environmental simulation test, and some tests also involves the analysis of the body's body fluids, tissues and excrement and other materials in the environmental pollution and metabolites content to determine the body by The extent of environmental pollution and the risk of damage, as is the case with biological testing.

       Material test: by changing the different fixtures, can be used for various types of materials for tensile strength, shear strength, peel strength, yield strength, ring strength, tensile, compression, bending, tearing, shear and other tests.
