During the use of electrical and electronic products, they often need to work in high and low temperature environments, so the high and low temperature testing of electrical and electronic products is particularly important. High and low temperature testing can help products determine suitable usage environments, evaluate product performance under different temperature environments, and ensure product reliability and stability. The following is some information about high and low temperature testing of electrical and electronic products.

1. Testing method

The detection of high and low temperatures in electrical and electronic products usually adopts the testing method of simulated environmental accelerated aging experiments or high and low temperature testers. By simulating accelerated aging experiments, it is possible to simulate the problems that may occur during long-term product use, such as temperature sensitivity and performance degradation, in a relatively short period of time. High and low temperature testers can test the performance of products in different temperature environments.

2. Temperature range

Different electrical and electronic products have different temperature requirements in different working environments, so the temperature range for high and low temperature testing will also vary. For example, the working environment of LED lights is usually -40 ℃~85 ℃, while the working environment of some precision instruments requires higher requirements, such as -70 ℃~200 ℃. Therefore, when conducting high and low temperature testing, it is necessary to determine the appropriate temperature range based on actual needs.

3. Testing content

The content of high and low temperature testing for electrical and electronic products usually includes but is not limited to the following aspects:

(1) The mechanical properties of the product, such as impact resistance, pressure resistance, and tensile strength.

(2) Electrical properties of the product: such as insulation resistance, capacitance and Dielectric strength of the product.

(3) The thermal performance of the product, such as its high and low temperature resistance, and the accuracy of the temperature sensor.

(4) The chemical properties of the product, such as its corrosion resistance and chemical composition.

Through the above testing, we can comprehensively understand the performance of the product in different temperature environments, providing assurance for the quality and reliability of the product.

Through strict testing and testing, the performance of the product can be evaluated under different temperature environments, providing a suitable environment for use, and ensuring the stability and reliability of the product. Our company has a team of professional engineers and industry elites, with three standardized laboratories covering an area of over 1800 square meters. We can undertake various testing projects such as electronic component testing and verification, IC authenticity identification, product design and material selection, failure analysis, functional testing, factory incoming material inspection, and tape weaving.
