Electrical testing is a crucial part of electronic product quality control. It is a process of determining whether an electronic product meets specifications and standards by testing its electrical parameters. In this article, we will introduce the basic principles and testing standards of electrical testing.

Basic principles of electrical testing

Electrical testing is the testing of the electrical characteristics of electronic products through the connection of input and output signals. When conducting electrical testing, the testing equipment will send specific signals to the electronic product and observe whether the output signal is normal. If the output signal does not match the input signal, or there is abnormal noise or interference, then the electronic product is judged as unqualified.

Electrical testing usually includes the following steps

Input of test signals: Test equipment will send specific test signals to electronic products, which are usually specific frequencies, voltages, or currents.

Output of test signals: Electronic products will output response signals, and testing equipment will observe whether these signals comply with design specifications.

Signal collection and analysis: The testing equipment will collect and analyze the signals output by electronic products.

Evaluation of test results: The test equipment will evaluate the electrical characteristics of electronic products based on the collection and analysis results of test signals.

Test standards for electrical testing

The testing standards for electrical testing are usually determined by the product specifications and standard specifications. Specifications and standard specifications usually include electrical parameters, testing methods, testing equipment, testing standards, etc. of electronic products. When conducting electrical testing, the testing standards and methods must be determined in accordance with the specifications and standard specifications.

Common electrical testing standards include

IEC standard: IEC is the abbreviation of the International Electrotechnical Commission, which is a globally recognized safety and performance standard for electrical and electronic components.

ANSI standard: ANSI is the abbreviation of the American National Standards Institute, and ANSI standard is the general electrical and electronic component standard in the United States.

UL standard: UL is the abbreviation for Underwriters Laboratory in the United States, and UL standard is one of the most authoritative safety certification standards in the United States.

TUV standard: TUV is the abbreviation of the German Technical Supervision Association (Technische Vereinigungigung fuer wirtschaftliche Zusammenarbeit), and TUV standard is a universal standard for electrical and electronic components in Germany.

The importance of electrical testing

Electrical testing is a crucial part of electronic product quality control. Through electrical testing, it is possible to determine whether the electrical characteristics of electronic products comply with specifications and standards, thereby ensuring the quality and safety of the product. If electrical testing is not conducted, it may lead to quality issues in electronic products and even lead to safety accidents.

To ensure product quality, enterprises should use testing equipment that meets industry and national standards, and follow corresponding testing standards for testing and evaluation.
