[0002] In the field of integrated circuit testing, the traditional open face strip testing method usually relies on flying probe measurement technology. However, this technology requires expensive flying probe measurement equipment as a support. When the test requirements are limited to a small number of strips, these devices often remain idle for a long time, making the investment uneconomical. In addition, the design of existing manual test tools also has limitations: they usually use a tray to fix the strip to be tested, and a manual test cover with pogopin to contact the test points on the strip. This design only allows testing of units at two fixed positions. Moreover, although automated measurement can be carried out using flying probe equipment, given the limited sampling quantity, the idle period of the equipment is too long, resulting in high purchase and maintenance costs.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0027] Refer to Figures 1-4 , an integrated - circuit strip testing device, including a hand - testing cover 1, a PCB board 2, a socket 3, a strip 4, and a metal backing plate 5. The metal backing plate 5 is provided with a first positioning post 51, and the first positioning post 51 is used to fix the strip 4 with positioning holes. The socket 3 is provided with spring probes for contacting the strip 4 to be tested. The number of spring probes on the strip 4 to be tested is 15. The RF signal line of the PCB board 2 leads the signal from the socket 3 to the SMA connector, and the SMA connector can be connected to the cable of the network analyzer for RF testing. The hand - testing cover 1 can press down the probes by rotation to make them contact the strip 4 for testing.
[0028] The hand - testing cover 1 is made of lightweight materials, which is convenient for the operator to hold and rotate. There are 2 second positioning posts 11 on its upper surface, and these positioning posts are precisely matched with the positioning holes on the metal backing plate 5 to ensure the stability and repeatability of the hand - testing cover 1 at different test positions.
[0029] The metal backing plate 5 serves as the basis of the entire testing device. There are 4 positioning blocks 53 on it to enhance the stability between the hand - testing cover 1 and the backing plate. At the same time, there are 2 first positioning holes 52 and 2 second positioning holes 53 on the backing plate, and these positioning holes respectively correspond to the test positions of the first unit 41 and the second unit 42 of the strip 4.
[0030] The strip 4 to be tested is precisely fixed by the cooperation of the positioning holes on it and the first positioning post 51 on the metal backing plate 5. The test units on the strip 4 are arranged according to the coordinates (7, 22) and (7, 24) to ensure that each unit can be accurately contacted by the probes.
[0031] Spring - probe configuration: There are 15 thin spring probes configured on the socket 3, and each probe corresponds to a pad on the strip 4. These probes are designed for elastic contact to meet the test requirements under different pressures and ensure the stability of signal transmission.
[0032] The RF signal line on the PCB board 2 transmits the signal contacted by the probe to the SMA connector. The SMA connector is designed to connect the cable of the network analyzer to achieve the RF performance test of the integrated circuit.
[0033] There are 4 positioning blocks 53 on the metal backing plate 5. There are 2 first positioning holes 52 and 2 second positioning holes 53 on the metal backing plate 5. The positioning blocks 53, the first positioning holes 52, and the second positioning holes 53 are used to position the manual test cover 1.
[0034] There are a first unit 41 and a second unit 42 on the strip 4. The unit coordinates of the first unit 41 and the second unit 42 are (7, 22) and (7, 24).
[0035] When the manual test cover 1 is placed at two positions on the left and right of the metal backing plate 5, the first unit 41 and the second unit 42 of each strip 4 can be tested respectively.
[0036] There are 2 second positioning posts 11 on the manual test cover 1. The second positioning posts 11 correspond to the first positioning holes 52 and the second positioning holes 53 of the metal backing plate 5.
[0037] When the second positioning post 11 of the manual test cover 1 is inserted into the first positioning hole 52 of the metal backing plate 5, the first unit 41 is tested.
[0038] When the second positioning post 11 of the manual test cover 1 is inserted into the second positioning hole 53 of the metal backing plate 5, the second unit 42 is tested.
[0039] Working principle:
[0040] Positioning of the strip 4: First, the strip 4 to be tested is matched with the first positioning post 51 on the metal backing plate 5 through the positioning hole on it to ensure the position of the strip 4 is fixed during the test.
[0041] Positioning of the manual test cover 1: Then, according to the unit to be tested (the first unit 41 or the second unit 42), the manual test cover 1 is placed at the corresponding position on the metal backing plate 5, and the precise positioning of the manual test cover 1 is achieved through the cooperation of the second positioning post 11 and the corresponding positioning hole on the metal backing plate 5.
[0042] Probe contact: The manual test cover 1 presses down the spring probe through a rotating action to make it contact the pad on the strip 4. This action needs to be completed manually by the operator, but the design ensures simple operation and good repeatability.
[0043] Signal test: Once the probe contacts the pad, the RF signal line on the PCB board 2 starts to work, transmitting the signal from the probe to the SMA connector. At this time, the operator can connect the cable of the network analyzer to the SMA connector and start the RF test.
[0044] Analysis of test results: After the test is completed, the operator can obtain the test data through a network analyzer and conduct corresponding analysis and evaluation.
[0045] This device is applicable to the scenario of small-batch manual sampling tests, which can significantly reduce the costs incurred by purchasing and maintaining automated test equipment. This device is not only compact and easy to carry, but also easy to operate, making it very suitable for factory operators to quickly get started.
[0046] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
