Description

Technical Field

[0001] This utility model relates to the field of test fixture technology, and in particular to a solderless test device for double-sided radio frequency devices. Background Technology

[0002] During the manufacturing process of multi-channel RF chips, their RF performance needs to be tested. To further increase RF channel density, leading companies use 3D packaging of multiple RF chips, with RF channels on both the upper and lower surfaces of the chip. Therefore, a testing device is needed to meet the requirements of RF channel testing in multiple dimensions. Since the purpose of this device is for large-scale factory testing, its design must maximize measurement efficiency and accuracy while eliminating the need for soldering, thus meeting the needs of mass production. Currently, RF chip testing is typically single-sided, and testing devices can only provide performance testing in a single dimension. Some companies use multiple test combinations for testing 3D packaged chips, which significantly increases testing time, affects testing efficiency, and introduces substantial production costs. Therefore, this invention proposes a solderless testing device for double-sided RF devices. Utility Model Content

[0003] The main objective of this invention is to provide a solderless testing device for double-sided radio frequency devices to solve the problems mentioned in the background art.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a solderless testing device for double-sided radio frequency devices, comprising a base, a receiving groove on the base, a lower test interface at the bottom of the receiving groove, a top seat covering the base, an upper test interface on the lower end face of the top seat, a plurality of guide posts on the lower end face of the top seat, and guide holes on the base corresponding to the guide posts, wherein the guide posts extend into the guide holes, and a self-locking insertion and removal mechanism is connected between the guide posts and the guide holes.

[0005] Preferably, the self-locking insertion and removal mechanism includes a locking block that slides radially within the guide hole. The guide post includes a guide portion, a connecting portion, and a tapered portion arranged coaxially from top to bottom.

An unlocking component is provided on the connecting portion.

[0006] Preferably, the unlocking component includes an unlocking block movably sleeved on the connecting portion. The unlocking block includes a first conical platform with its smaller end facing upward and a second conical platform coaxially disposed on the lower end face of the first conical platform with its smaller end facing downward. The maximum diameter of the second conical platform is smaller than the maximum diameter of the first conical platform. A second spring is sleeved on the connecting portion. A spring receiving groove is provided on the lower end face of the second conical platform. The second spring is located in the spring receiving groove. The second spring is used to keep the unlocking block away from the conical portion. The locking block extends between the conical portion and the second conical platform.

[0012] The present invention will be further described in detail below with reference to specific embodiments.

[0013] Example: like Figure 1 and Figure 2As shown, this utility model discloses a solderless testing device for double-sided radio frequency (RF) devices, comprising a base 1, a receiving groove 2 on the base 1, a lower test interface 3 at the bottom of the receiving groove 2, a top seat 4 covering the base 1, an upper test interface 5 on the lower end face of the top seat 4, multiple guide posts 6 on the lower end face of the top seat 4, and guide holes 7 on the base 1 corresponding to the guide posts 6. The guide posts 6 extend into the guide holes 7, and a self-locking insertion / removal mechanism 8 connects the guide posts 6 and the guide holes 7. Both the upper test interface and the lower test interface are connected to an RF testing machine. By placing the RF device in the receiving groove 2 on the base 1 and covering the base 1 with the top seat 4, the self-locking insertion / removal mechanism 8 locks the top seat 4 and the base 1 together, causing the upper test interface 5 and the lower test structure to abut against the upper and lower test points of the RF device, respectively. The RF testing machine then enables simultaneous testing of both sides of the RF device, improving testing efficiency.

[0014] The self-locking insertion and removal mechanism 8 includes a locking block 9 that slides radially within the guide hole 7. The guide post 6 includes a guide portion 10, a connecting portion 11, and a tapered portion 12 arranged coaxially from top to bottom. A locking groove 13 is formed between the guide portion 10 and the tapered portion 12. A sliding groove 14 is provided on the inner wall of the guide hole 7. The locking block 9 is slidably connected within the sliding groove 14. One end of the locking block 9 extends into the locking groove 13, and the other end of the locking block 9 is connected to a spring 15 for maintaining its extended state, thereby locking the base 1 and the top seat 4. An unlocking component 16 is provided on the connecting portion 11. The locking block 9 can be unlocked through the unlocking component 16, thereby separating the base 1 and the top seat 4 for easy replacement of radio frequency devices.

[0015] The unlocking component 16 includes an unlocking block 17 movably sleeved on the connecting part 11. The unlocking block 17 includes a first conical platform 18 with its small end facing upward and a second conical platform 19 coaxially disposed on the lower end face of the first conical platform 18 with its small end facing downward. The maximum diameter of the second conical platform 19 is smaller than the maximum diameter of the first conical platform 18. A second spring 20 is sleeved on the connecting part 11. The lower end face of the second conical platform 19 is provided with a spring receiving groove 21. The second spring 20 is located in the spring receiving groove 21. The second spring 20 is used to keep the unlocking block 17 away from the conical part 12. The locking block 9 extends between the conical part 12 and the second conical platform 19. The protruding end of the locking block 9 is provided as an upward inclined surface 22. When the top seat 4 is placed on the base 1, the guide post 6 extends into the guide hole 7 and presses down on the top seat 4. The conical part 12 pushes the locking block 9 outward, thereby pushing the locking block 9 into the slide groove 14. The spring 15 is compressed, the guide post 6 continues downward, and the conical part 12 moves below the locking block 9. The locking block 9 is no longer compressed and, under the elastic force of the spring 15, extends between the conical part 12 and the second conical platform 19. The conical part 12 is blocked by the locking block 9, thus locking the base 1 and the top seat 4. When it is necessary to replace the RF device, the top seat 4 is pressed down further, and the conical surface of the second conical platform 19 and the locking block 14 are locked together. The inclined surface 22 of the locking block 9 cooperates to push the locking block 9 back into the slide groove 14. When the large-diameter end of the first conical platform 18 moves to below the locking block 9, the locking block 9 extends under the elastic force of the spring 15 and abuts against the conical surface of the first conical platform 18. At this time, the top seat 4 is pulled upward, and the locking block 9 abuts against the first conical platform 18 to block it. The conical part 12 moves upward until it is close to the first conical platform 18. If the top seat 4 is pulled further, the end of the locking block 9 passes over the conical surface of the first conical platform 18 and abuts against the conical surface of the conical part 12, thereby the guide post 6 can be pulled out from the guide hole 7, realizing the separation of the top seat 4 and the base 1.

[0016] A third spring 23 is sleeved on the connecting part 11. The top end of the third spring 23 is connected to the lower end surface of the top seat 4, and a washer 24 is connected to the bottom end of the third spring 23. The washer 24 abuts against the upper end surface of the base 1.

[0017] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
