High temperature testing of electrical and electronic products

Under high temperature conditions, the parts and materials used in the product may soften, reduce performance, change characteristics, potential damage, oxidation and other phenomena at high temperatures. High-temperature testing of electronic and electrical products is to determine the ability of components, equipment or other products to be used, transported or stored in low-temperature environments. High temperature tests are divided into high temperature tests (temperature gradient) for heat dissipation samples and high temperature tests (temperature gradient) for non-heat dissipation test samples.
Zhongke Testing Reliability Experiment Center has environmental testing capabilities for various electrical and electronic products, and provides professional high-temperature testing services for heat dissipation and non-heat dissipation electrical and electronic products.

1. Test Bb: High temperature test of non-heat dissipation test sample temperature gradient
This test method is used to conduct high-temperature tests on non-heat-dissipating test samples. The test samples are placed under high-temperature conditions for a long enough time to achieve temperature stability.
2. Test B: Heat dissipation test. High temperature test of product temperature gradient. The test sample is not powered during the temperature adjustment period.
This test method is used to conduct high-temperature tests on heat dissipation test samples. The test samples are placed under high-temperature conditions for a long enough time to achieve temperature stability.
3. Test Be: High-temperature test of heat dissipation test sample temperature gradient - the test sample is energized during the entire test process
This test method is used to conduct high-temperature tests on heat dissipation test samples. The test samples are placed under high temperature conditions for a long enough time to achieve temperature stability, and the test samples are required to be powered during the entire test process.
