With the development of information technology and the popularization of electronic products, the quality inspection and certification of electronic components have become an important topic. Electronic components, including sensors, transistors, integrated circuits, etc., play an important role in electronic products, but if used improperly, they may also bring safety hazards. Therefore, in order to ensure the safety of electronic products, quality testing and certification of electronic components are essential.

1、 Quality inspection of electronic components

The quality inspection of electronic components mainly includes three aspects: appearance inspection, parameter measurement, and functional testing.

Visual inspection

Appearance inspection refers to the observation and inspection of the appearance of electronic components. By observing, it is possible to determine whether electronic components are damaged, deformed, rusted, etc. In addition, electronic components can also be checked for obvious defects or damage.

parameter measurement

Parameter measurement refers to the measurement of the parameters of electronic components to determine whether their performance meets the requirements. Parameter measurement mainly includes resistance, capacitance, inductance, voltage, current, etc. By measuring parameters, it can be determined whether electronic components meet design requirements and whether there are performance defects.

functional testing

Function test refers to the function test of electronic components to determine whether they work normally. Functional testing mainly includes testing of switching, amplification, filtering, and other functions. Through function test, it can be determined whether the electronic components work normally and can achieve the expected effect.

2、 Certification of electronic components

The certification of electronic components mainly includes two aspects: certification standards and certification testing.

Certification standards

The certification standards for electronic components mainly include three aspects: safety standards, performance standards, and quality standards.

Safety standards refer to the standards for certifying the safety of electronic components. For example, UL and CE certification in the United States, ETL certification in Europe, etc. These certification standards regulate the electrical safety, mechanical safety, environmental protection, and other aspects of electronic components.

Performance standards refer to the standards for certifying the performance of electronic components. For example, FDA certification in the United States, ISO13485 certification in Europe, etc. These certification standards specify the performance of electronic components, such as stability, reliability, and response speed.

Quality standards refer to the standards for certifying the quality of electronic components. For example, TUV certification in Germany. These certification standards specify the quality of electronic components, such as chemical composition, physical structure, manufacturing process, etc.

Certification testing

Certification testing refers to testing and evaluating electronic components in accordance with certification standards to determine whether they meet certification requirements.

Certification testing mainly includes electrical safety testing, mechanical safety testing, chemical testing, physical testing, performance testing, and environmental testing. Among them, electrical safety test is the most important test, which mainly includes Short-circuit test, over-voltage test, over-current test, etc. Mechanical safety testing mainly includes vibration resistance testing, bending resistance testing, impact resistance testing, etc. Chemical testing mainly includes chemical composition analysis, elemental analysis, etc. Physical testing mainly includes size testing, weight testing, appearance inspection, etc. Performance testing mainly includes stability testing, reliability testing, response speed testing, etc. Environmental testing mainly includes high temperature testing, low temperature testing, humidity testing, salt spray testing, etc.

Through the discussion in this article, we can see that the quality inspection and certification of electronic components are crucial for ensuring the safety of electronic products. To ensure the safety of electronic products, it is necessary to strengthen the quality testing and certification of electronic components, in order to ensure the quality and safety of products.
