Abstract

The invention innovatively provides an SXM2GPU-simulated test alarm device. A simulation device and a to-be-tested board card are connected via two sets of connectors, in-place signals of the two setsof connectors are introduced, when the connector at any end is not in place, a sound circuit gives an alarm, so that not only irreversible damage to the board card such as the GPU can be avoided, butalso the GPU simulation test can be realized, the testing effect is better, the testing efficiency and precision are improved, and the testing cost is reduced. In addition, according to the technicalscheme in the invention, an indicator lamp circuit and a Schmidt trigger circuit are further introduced, so that not only the test personnel can monitor the test process more visually, thereby facilitating the test personnel to find problems timely and adjust the problems, but also the in-place signals are more optimized, thereby improving the anti-interference capability.

Description

technical field [0001] The invention relates to the field of GPU testing, in particular to a test alarm device for simulating SXM2GPU. Background technique [0002] With the rapid development of AI servers (complex instruction set architecture servers, also known as PC servers), each PCBA (Printed Circuit Board + Assembly) on the server, that is, the empty PCB board is mounted on the surface assembly technology, and then double-in-line The entire process of the packaging technology plug-in) carries more and more components and components, which may cause the board to bear excessive strain and cause failure problems such as tin cracking or breaking of the board. In order to scientifically detect the stress value of the board during assembly and transportation, it is necessary to design a set of monitoring methods for the dynamic strain force of the internal board of the server. [0003] During the reliability test, the vibration, impact, and drop tests without starting up ar...
