Description

Technical Field

[0001] The present invention relates to the field of industrial production and further to a product detection tool. Background Art

[0002] SIP packaging (system in a package) is a common packaging method in industrial production. It integrates multiple functional wafers, including processors, memory and other functional wafers into one package according to application scenarios, number of packaging substrate layers and other factors, thereby realizing a packaging solution with basic complete functions.

[0003] After SIP packaging is completed, it is usually necessary to test its specified performance. During the test process, it is usually necessary to test multiple points at the same time. Currently, when it is necessary to test multiple points at the same time, the operator needs to hold multiple test probes at the same time to test.

[0004] It should be pointed out that when the number of points to be tested exceeds five, the operator needs to fix more than five probes on the SIP package with a smaller size at the same time, which is very difficult to operate; and if the operator's hand shakes slightly, the test probe will slip, resulting in inaccurate testing. In addition, when the pin points to be tested on the SIP package are adjacent, the minimum distance is only 0.55mm. When the operator manually operates, the adjacent probes are easy to touch each other, resulting in an inability to perform stable testing. Importantly, in the existing test mode, the operator needs to keep the probe on the tiny test point for a long time, which can easily cause visual fatigue to the operator and reduce work efficiency.

[0005] In summary, it is necessary to improve the traditional testing devices and testing methods. Summary of the invention

[0006] In response to the above technical problems, the purpose of the present invention is to provide a product inspection tool, which can adjust and fix multiple probes to multiple positions and can lift and lower multiple probes at the same time, thereby reducing the operator's operating difficulty and work intensity and improving inspection efficiency.

[0058] It should be noted that, in this preferred embodiment, both ends of the first rotating block 422 of the angle adjustment member 42 are rotatable relative to the fixed block 421 and the probe pen mounting block 423, respectively, so that not only the angle of the probe pen 41 relative to the base 1 can be adjusted, but also the height of the probe pen 41 relative to the base 1 can be adjusted. Optionally, in other preferred embodiments of the present invention, the number of the first rotating blocks 422 between the fixed block 421 and the probe pen mounting block 423 can also be multiple, and the specific number of the first rotating blocks 422 between the fixed block 421 and the probe pen mounting block 423 should not constitute a limitation to the present invention.

Similarly, the size of the probe pen mounting block 423 is slightly larger than the distance between the two second extension arms 4226, and the probe pen mounting block 423 and the two second extension arms 4226 are connected by interference fit to achieve a damping connection.

[0061] It should also be pointed out that the tightness of the interference fit between the two first extension arms 4222 and the fixing block 421 can be adjusted through the first bolt assembly 4224, and the tightness of the interference fit between the two second extension arms 4226 and the probe fixing block 423 can be adjusted through the second bolt assembly 4228.

[0064] Furthermore, the product inspection tool includes an image acquisition component 5 and a display, wherein the image acquisition component 5 is used to acquire an image on the mounting position 11 of the base 1 and transmit it to the display for display. After the image acquisition component 5 acquires the image on the mounting position 11 on the base 1, it can transmit it to the display and display it in an enlarged manner on the display, so that the operator can better align the probe 41 with the test point on the package to be inspected.

[0065] Reference Manual Attached Figure 7 In the preferred embodiment, the needle of the probe pen 41 is retractable, which can facilitate the control of the pressure applied by the probe pen 41 to the package to be tested, thereby avoiding damage to the package to be tested due to high pressure applied to the package to be tested.

[0066] Specifically, the probe pen 41 includes a mounting rod 411, an elastic probe 412 and a needle mounting component 413, the needle 412 is detachably mounted on the needle mounting component 413, the needle mounting component 413 is detachably mounted on the mounting rod 411, and the needle 412 is electrically connected to the needle mounting component 413, and the needle mounting component 413 is suitable for communication connection with the outside world.
