[0002] With the rapid development of server performance, the diversity and structure of servers are becoming more complex, so the testing of motherboards is becoming more and more complex, with more and more test items and more stringent test accuracy. In order to better test the power integrity of server boards, especially to test the power integrity of CPU and MEMORYVR more accurately, Intel launched the GEN4VRTT test fixture and GEN5VRTT test fixture.

[0003] At present, the installation method of GEN5VRTT test fixture requires using Male to Male Header as a connector to connect VRTT and Interposer. In order to facilitate the installation of Male to Male Header and ensure the protection of the pins on Male to Male Header during installation, Intel has designed two foolproof holes on Interposer and System Under Test respectively. There are two fixing columns on Male to Male Header to insert into the foolproof holes, which is convenient for installation and plays a fixing role. When using VRTT test fixture, the VRTTTool with a fixer needs to be inserted into the Interposer on the motherboard, and positioned and fixed by the metal column on the connector.

[0004] When using VRTT test jig to test the power module, it is impossible to accurately control the ambient temperature and airflow, resulting in distortion of the test environment and insufficient test results. Utility Model Content

[0026] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] For details, please refer to Figure 1 , the server power module test device includes:

[0029] A VRTT test jig 1 is provided, wherein the VRTT test jig 1 is installed above the power module, a fan is provided on the top of the VRTT test jig 1, and an air suction port 11 is provided on the bottom of the side of the VRTT test jig 1; the bottom of the VRTT test jig 1 is connected to an air guide hood 2, the air guide hood 2 covers the air suction port 11 and the power module, an air inlet 21 of the air guide hood 2 is provided in front of the power module, and the air guide hood 2 guides the airflow from the air inlet 21 to the air suction port 11 through the power module; a heater is provided at the air inlet 21 of the air guide hood 2, and temperature sensors are provided around the power module, and the heater and the temperature sensor are electrically connected to the controller.

[0030] Specifically, the VRTT test fixture 1 includes a shell, which is a square tube; the top of the square tube is connected to an exhaust fan; and air suction ports 11 are provided at the bottoms of both sides of the square tube.

[0031] Among them, the size of the air guide cover 2 is not limited, but it must be able to completely cover the power module and the air inlet 11 of the VRTT test fixture 1, and the air inlet 21 of the air guide cover 2 must be in front of the power module, so as to change the wind flow direction from the power module to increase the area of ​​the wind flow through the power module, so that the response of the power module to the ambient temperature can be verified simultaneously, and the wind flow rate can also be controlled by the fan of the VRTT test fixture 1. Therefore, when verifying the power supply performance of the power module, the power supply performance changes of the power module under any wind speed can be verified simultaneously.

[0032] By installing a heater at the air inlet 21 of the air guide 2, the airflow drives the heater to let the hot air flow flow through the air guide 2 to quickly increase the ambient temperature. Then, the ambient temperature of the power module is collected by the temperature sensor to achieve the purpose of simulating the change of the power supply performance of the power module at different temperatures.

[0033] When executing the test, the controller uploads the temperature collected by the temperature sensor to the host computer. At the same time, the controller receives the target temperature sent by the host computer and controls the working state of the heater based on the target temperature.

[0034] The controller uses a complex programmable logic device. The controller is connected to the host computer through a serial port line. The host computer runs a test script to perform a voltage stability test on the power module of the server under test.

[0035] The heater uses a heating resistor. The heating resistor is connected to a power supply via a MOS switch, and the control pin of the MOS switch is electrically connected to a controller. When the temperature collected by the temperature sensor does not reach the target temperature, the controller controls the MOS switch to close, and when the temperature reaches the target temperature, the controller controls the MOS switch to open.

[0036] The existing VRTT test fixture 1 installation method requires plugging and unplugging the PIN pin 32, which easily leads to poor contact. Therefore, the connection structure is improved. Figure 2As shown, the adapter board is provided with a first plug hole, the side wall of the VRTT test fixture 1 is provided with a second plug hole, the side wall of the connector 3 is connected with a retractable fixing column 31, the upper part of the retractable fixing column 31 is connected to the second plug hole, and the lower part of the retractable fixing column 31 is connected to the first plug hole. Male to Male Header is used as connector 3, and VRTT and Interposer are connected through PIN pin 32 and matching jack.

[0037] like Figure 3 As shown, the telescopic fixed column 31 includes a first column 311 and a second column 312. A cavity is provided inside the first column 311, and a sliding block 314 is provided in the cavity. A connecting rod 313 is provided at the lower part of the sliding block 314, and the end of the connecting rod 313 is connected to the second column 312. The upper fixed column and the lower fixed column have the same diameter, and the surface of the sliding block 314 is provided with a rubber anti-slip layer.

[0038] The use of the retractable fixing column 31 as the positioning structure can avoid damage to the PIN needle 32 when installing the VRTT test fixture 1, thereby preventing poor contact.

[0039] Although the utility model is described in detail by referring to the accompanying drawings and in combination with the preferred embodiments, the utility model is not limited thereto. Without departing from the spirit and essence of the utility model, a person skilled in the art may make various equivalent modifications or substitutions to the embodiments of the utility model, and these modifications or substitutions shall be within the scope of the utility model. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the utility model, and they shall be within the scope of protection of the utility model.
