Description

Technical Field

[0001] The utility model relates to the field of electrical technology, in particular to a high-stability electrical component testing system. Background Art

[0002] Over the past few decades, the use of electrical components in automobiles has expanded rapidly, becoming one of the fastest-growing market segments. For all automotive products, quality, reliability, and service life are primary considerations when selecting components.

[0003] The operating environment of automotive electronic components is complex and varied, and their operating temperature range is wider than that of consumer products. For example, components around the engine must withstand extreme temperatures ranging from -40°C to 150°C, while those in the passenger compartment must operate between -40°C and 85°C. Conventional consumer electronics, on the other hand, typically operate within a range of 0°C to 70°C.

[0004] In addition to temperature factors, automotive electronic components must also withstand environmental challenges such as higher humidity, mold, dust, water, EMC, and harmful gas corrosion. These requirements far exceed those of consumer electronics.

[0005] Mechanical durability: Cars experience various vibrations and shocks during operation, so their electronic components must have higher mechanical durability to cope with complex and changing driving environments.

[0006] Reliability Assurance: The reliability of automotive electronic systems is crucial. To ensure efficient and stable system operation, the service life of each electronic component must be extended. Furthermore, in complex systems, the reliability requirements of each component also increase. Therefore, to ensure the reliability of the entire vehicle, every electronic component must be rigorously screened and tested.

[0007] The existing solution for the above test equipment is to conduct separate tests. The actual use scenario requires comprehensive matching tests of temperature and humidity under various working conditions. A single condition test and the actual use scenario cannot well restore the actual effect. For this reason, we propose a high-stability electrical component testing system. Utility Model Content
