[0003] like Figure 1 As shown in FIG. 1 , it can be seen that the two channels in the middle are close to the airflow outlet, while the two channels on the sides are far from the airflow outlet. Figure 2 As shown, the temperature response of the two channels in the middle is faster, while the temperature response of the two channels on both sides is slower.

[0004] At the same time, the above structural design will also lead to a large temperature difference between the two channels in the middle and the two channels on the sides, and the temperature of the four channels cannot reach the target temperature of ±5°C. For example, the target temperature is 35°C, that is, the four channels need to reach 30°C to 40°C before the test can begin. However, in the actual working process, when the temperature of the two channels in the middle has met the required temperature (that is, the temperature reaches 30-40°C), the actual temperature of the two channels on the sides cannot reach the required temperature, so the immersion temperature continues to rise; when the immersion time reaches 100 seconds (that is, Figure 2 However, most machines cannot make the temperature in each channel reach the required temperature within 100 seconds, so the test efficiency is low, and it cannot guarantee that the module is tested within the required temperature range, and the test conditions are not rigorous.

[0005] Figure 2 The terms in the text are explained as follows:

[0006] Set Temp: target temperature;

[0007] Set Soak Time: The soaking time is the time the product needs to be kept within the target temperature ±1°C;

[0008] AirTemp: The temperature sensor at the output of the airflow meter. This value is read back by the software.

[0009] DUT Temp: The airflow meter is connected to the temperature sensor around the product, and this value is read back by the software;

[0010] Soak time: real-time recording of soaking time;

[0011] Socket 1\2\3\4: The module internal chip temperature value read by each channel. Utility Model Content

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0038] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] like Figure 3-Figure 8 As shown, the present embodiment provides a flow diversion block drainage device 100, comprising a flow diversion body 1, a fluid inlet 2 is provided on the first side wall 5 of the flow diversion body 1, and two fluid outlets 3 are symmetrically provided on the second side wall 6 of the flow diversion body 1, the fluid inlet 2 is connected to the two fluid outlets 3, and the two fluid outlets 3 are respectively provided near the two ends of the second side wall 6, the first side wall 5 and the second side wall 6 are opposite, the fluid inlet 2 is connected to the air flow source, thereby realizing the provision of air flow, there is a spacing between the two fluid outlets 3 and the four channels of the machine, the air flow is dispersed and output through the two fluid outlets 3, one of the fluid outlets 3 is directed toward the first channel 200 and the second channel 300 of the machine, and then the air flow is directed toward the first channel 200 and the second channel 300 of the machine through the fluid outlet 3. The first channel 200 and the second channel 300 supply air, and the other fluid outlet 3 is directed toward between the third channel 400 and the fourth channel 500 of the machine, and then air is supplied to the third channel 400 and the fourth channel 500 through this fluid outlet 3, so that air is evenly supplied to the four channels, and the temperature distribution in each channel is more uniform. At the same time, the air volume is dispersed in two directions through the two fluid outlets 3, which reduces the wind speed and air volume of a single air outlet, thereby reducing the noise level. In addition, the design of the two fluid outlets 3 is more flexible, and there is no need to additionally set up a guide plate or a guide groove. By reasonably designing and optimizing the output port structure, the precise adjustment of the airflow outlet direction can be achieved to meet different application requirements.

[0040] Specifically, the diverter body 1 is a rectangular parallelepiped, and two fluid outlets 3 are respectively opened at two corners of the diverter body 1. When in use, the first side wall 5 where the fluid inlet 2 is located is set toward the airflow source, and the second side wall 6 sandwiched by the two fluid outlets 3 is set toward the four channels.

[0041] A cylindrical groove is formed on the first side wall 5 , and the open end of the cylindrical groove forms a fluid inlet 2 . The circular fluid inlet 2 can better control the entry direction of the fluid and realize concentrated input airflow.

[0042] Two cylindrical holes are also provided in the diverter body 1, one end of the two cylindrical holes extends to the inner bottom surface of the cylindrical groove and is connected to the inside of the cylindrical groove, the other end of the cylindrical hole extends to the corner of the diverter body 1, and a fluid outlet 3 is formed on the end of the cylindrical hole away from the cylindrical groove, that is, the two cylindrical holes are equivalent to being formed by directly opening holes through the inner bottom surface of the cylindrical groove in the direction close to the second side wall 6.

[0043] The angle between the center line of the cylindrical groove and the center line of the cylindrical hole is 40°, and the inner diameter of the cylindrical hole is 16 mm, which fits the channel position distribution of the current machine, so that the fluid outlet 3 can cover four channels at the same time, that is, cover four test modules.

[0044] A plurality of threaded holes 4 are provided on the side wall of the diverter body 1. The diverter body 1 is mounted on the machine platform by screws passing through the threaded holes 4. The screws are M4 screws, which can be directly fixed by manually installing the M4 screws, and the placement angle of the diverter body 1 can be flexibly adjusted.

[0045] There are two threaded holes 4 , which are respectively opened on two oppositely disposed side walls of the flow dividing body 1 .

[0046] The flow dividing body 1 is made of polytetrafluoroethylene material, which has excellent heat resistance and cold resistance and can be used for a long time under the condition of -180℃~260℃.

[0047] Through the above design, this embodiment achieves relatively close temperatures of the four channels and can reach the target temperature of ±5°C in a short time without waiting for 100 seconds, which significantly improves the test efficiency. Through calculation, UPH (the number of units completed per hour) is increased from 18 to 22, an increase of 22.2%.

[0048] The present embodiment can also be adjusted as follows to apply the flow splitter body 1 to different test benches:

[0049] Adjust the direction of the fluid outlet 3: By adjusting the direction of the fluid outlet 3, the direction and distribution of the airflow can be changed, thereby achieving control of the fluid flow;

[0050] Adjusting the width of the fluid outlet 3: Adjusting the width of the fluid outlet 3 can change the width of the flow channel, thereby adjusting the speed and distribution of the airflow;

[0051] Adjusting the position and shape of the diverter body 1: Adjusting the position and shape of the diverter body 1 can change the shape and length of the airflow, thereby achieving precise control and distribution of the airflow, which is suitable for various scenarios.

[0052] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope.
