Description

Technical Field

[0001] The utility model patent relates to a power supply detection and testing tool, in particular to a load point power supply detection and testing tool. Background Art

[0002] In terms of point-of-load power supplies, foreign countries have achieved very great results. Major manufacturers such as Tl, Eriesson, Artesyn, Astec, Syncor, Delta, Linear, Tyco, C&D and others have launched their own point-of-load power supply products and power management chips.

[0003] In China, high-power, multi-channel, high-density point-of-load power supplies are still in their infancy. Some products have related replacement solutions in China. In the future, point-of-load power supplies will become an industrial chain and gradually replace foreign products. Therefore, the detection and testing of the corresponding point-of-load power supplies is imminent. This design gives a detailed introduction to the design of the detection and testing tooling for point-of-load power supplies.

[0004] At present, when the load point power supply is fully tested, in order to improve the test accuracy, the load point power supply will be directly soldered on a dedicated circuit board and then the full function test will be performed. This detection method has high accuracy, but the load point power supply after the test needs to be desoldered for the second time, which will damage the original spherical solder column of the load point power supply and affect the reliability of the secondary welding.
