Technical Field

[0001] This utility model relates to the field of electronic equipment testing technology, and in particular to a waveguide-type SIP module vacuum fixture for the W-band. Background Technology

[0002] When testing the performance data of waveguide-type SIP modules, the installation method involves manually tightening screws to secure the SIP modules. This method takes approximately 3-4 minutes to install and remove the SIP modules, and the inconsistent torque of the screws can easily damage the product, making it time-consuming and labor-intensive. Furthermore, the positional tolerance of the waveguide-type SIP modules is ±0.1mm, which cannot adequately guarantee assembly consistency, thus increasing the error in the test data and affecting the standard deviation of the test data consistency.

[0003] Moreover, screw installation is not as well adapted to automated control upgrades, increasing personnel input and introducing more uncertainties. Utility Model Content

[0010] Furthermore, the surface of the testing stage is provided with an arc-shaped positioning post, which is adapted to the arc-shaped groove on the edge of the waveguide-type SIP module.

[0011] Furthermore, the vacuum cavity is provided with multiple supporting cylinders, which are evenly arranged around the connecting hole.

[0012] Furthermore, two right-angle waveguide ports are provided at the front end, and four right-angle waveguide ports are provided at the rear end.

Detailed Implementation

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] See Figures 1-3 This utility model provides a technical solution:

[0022] Example:

[0023] like Figures 1-3 As shown, a vacuum fixture for a W-band waveguide-type SIP module includes a testing stage 1. The waveguide-type SIP module 2 is disposed on the surface of the testing stage 1. The testing stage 1 is provided with a front right-angle waveguide port 3, a front straight-through waveguide calibration port 4, a rear right-angle waveguide port 5, and a rear straight-through waveguide calibration port 6. The front right-angle waveguide port 3 and the front straight-through waveguide calibration port 4 are located on the same side. The front right-angle waveguide port 3 corresponds to the front transceiver channel of the waveguide-type SIP module 2. The rear right-angle waveguide port 5 and the rear straight-through waveguide calibration port 6 are located on the same side. The rear right-angle waveguide port 5 corresponds to the rear transceiver channel of the waveguide-type SIP module 2.

[0024] The surface of the testing stage 1 is provided with a recessed vacuum cavity 7, which is connected to a vacuum generator via a vacuum tube. The vacuum generator is existing technology, and its structure and principle will not be described in detail here.

[0025] The testing stage 1 is provided with a communication hole 8 that communicates with the vacuum chamber, and the vacuum tube is connected to the vacuum chamber 7 through the communication hole 8.

[0026] The surface of the testing stage 1 is provided with strip-shaped positioning posts 9, which are adapted to the grooves on the waveguide-type SIP module 2. The strip-shaped positioning posts 9 are used to cooperate with the grooves on the back of the waveguide-type SIP module 2 to position the grooves, thereby achieving fast and accurate positioning of the waveguide-type SIP module 2 and ensuring the effect of negative pressure fixation.

[0027] The surface of the testing stage 1 is provided with an arc-shaped positioning post 10, which is adapted to the arc-shaped groove on the edge of the waveguide-type SIP module 2. The arc-shaped positioning post 10 is positioned close to the strip post. The arc-shaped positioning post 10 is designed for visualization, so it is easier to see whether the waveguide-type SIP module 2 is positioned accurately. At the same time, the arc-shaped positioning post 10 can be provided with threaded holes, so that when the negative pressure fails, it can be used with bolts to fix the waveguide-type SIP module 2.

[0028] The vacuum cavity 7 is provided with multiple supporting cylinders 11, which are evenly arranged around the connecting hole 8. The supporting cylinders 11 are used to provide support for the waveguide-type SIP module 2 and prevent the waveguide-type SIP module 2 from deforming under stress.

[0029] Two right-angle waveguide ports 3 are provided at the front end, and four right-angle waveguide ports 5 are provided at the rear end.

[0030] The testing table 1 has a mounting platform 12 on its side, and the mounting platform 12 has threaded holes. The mounting platform 12 and the threaded holes facilitate the installation of the testing table 1 onto the workbench using bolts and screws.

[0031] The system includes: 1. Front-end transceiver channels with ports 1 and 2; and back-end transceiver channels with ports 11, 12, 21, and 22. 2. Back-end right-angle waveguide ports 11 and 12 (and ports 21 and 22) are used in conjunction with front-end transceiver channel port 1 (or port 2). Waveguide probes and instruments are connected to the front and back ports respectively to complete the receiver gain and transmitter power tests. 3. A square slot is provided on the surface of the test station 1. This slot facilitates the removal of the waveguide-type SIP module 2 at the end of the test. The slot is located on the side of the waveguide-type SIP module 2 (vacuum cavity 7).

[0032] Working principle: The waveguide SIP module is positioned by strip-shaped and arc-shaped positioning posts, ensuring precise support on the test stage surface. A vacuum tube is then connected, and the electric valve is controlled to switch the vacuum on and off, achieving the ability to adsorb (fix) the waveguide SIP module (the adsorption force is intelligently controllable). The time to load and unload a single waveguide SIP module is approximately 5 seconds, reducing manual labor, saving loading and unloading time, improving the consistency of product test data, achieving automated control, and increasing production efficiency.

[0033] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
