Description

Technical Field

[0001] The present invention relates to the technical field of mainboard detection, and in particular to a server mainboard fault diagnosis device with a USB interface. Background Art

[0002] A server with a USB interface is equipped with a motherboard inside. The motherboard is the connection and management hub for hardware such as the USB interface and provides the server operating environment. When a server motherboard fails, the motherboard needs to be diagnosed and repaired. A motherboard fault diagnosis device is required for motherboard diagnosis. The motherboard is placed inside the device, and the diagnostic components of the device are attached to the motherboard to diagnose the damaged area on the motherboard. The detected error is fed back to the computer, so that the motherboard can be repaired.

[0003] According to CN202510175228.2, the present invention discloses a method and system for online fully automatic detection of printed circuit board defects based on data analysis, which relates to the technical field of printed circuit board performance testing. The invention realizes a comprehensive evaluation of the performance of the circuit board through steps one to four. By configuring the test system and setting the test conditions, the accurate installation and debugging of each test module are ensured; by calculating the power stability index Dyw, the power switching fault tolerance index Qhrc, the thermal stress index Ryl, the mechanical stress index Mvz, the electromagnetic compatibility index Jrx, the resource contention index Zyzq and the self-repair index Xfz, the related calculations are performed to obtain the comprehensive evaluation index Pc, and a performance evaluation is performed to effectively determine whether the circuit board is qualified. When the comprehensive evaluation index Pc is lower than the first performance threshold X, a performance failure label is generated, and an in-depth hierarchical evaluation is performed through the second multi-level evaluation module to facilitate the identification of specific performance defects.
