Description

Technical Field

[0001] This utility model relates to the field of packaged product testing, and in particular to a YC1-05A packaged product testing device. Background Technology

[0002] Our company has never had a dedicated testing device for testing the electrical parameters of our YC1-05A packaged semiconductor discrete device. This type of packaged product has a metal package shape, with a cylindrical raised electrode mounted on one side of the product and a bolt mounted in the middle of the product. The bolt head and the cylindrical raised electrode are on the same side of the product.

[0003] The electrical parameter testing of this product is generally carried out by using a test fixture for the axial product or by using a test wire clamp with alligator clips to directly test the cylindrical protruding electrode at one end of the product and the metal bolt at the other end of the product. The testing operation is extremely inconvenient, and the accuracy of the test results is not high. During the test, the product often falls off due to the electrode clamping method being not secure, which can lead to product damage in severe cases, seriously limiting the testing efficiency of this type of packaged product.

[0014] The beneficial effects of this utility model are as follows: It adopts a snap-on flip-top cover design. During testing, the cover is fixed on the test base, and the buckle on the edge of the cover is manually lifted to open the cover. At the same time, the product to be tested is placed on the test plate, and then the buckle is fastened to the test plate, so that the cover is fastened to the test base. At the same time, the fixing mechanism limits and stabilizes the product. The cover presses the product, and the first and second probes elastically retract, ensuring good flexible contact between the four electrodes and the test probes, avoiding damage to the product, ensuring good circuit continuity, and pressing the test button to complete the test operation.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0020] In this embodiment, refer to Figure 1 and Figure 2 It includes a test base 1, which is equipped with a Kelvin setting plug to facilitate connecting the test base 1 to the test system and realize circuit connection.

[0021] A sample slot 2 is provided in the middle of the test base 1. A first probe 3 and a second probe 4 are fixedly installed in the sample slot 2. Both the first probe 3 and the second probe 4 are set in a columnar manner. A test plate 6 is installed on the test base 1. The test plate 6 is made of insulating material. A through hole is provided in the middle of the test plate 6. The sample slot 2 is connected to the through hole of the test plate 6, so that the needles of the first probe 3 and the second probe 4 point to the through hole.

[0022] There are two first probes 3 and two second probes 4, for a total of four probes. The test circuit adopts a Kelvin test circuit design. Both the first probes 3 and the second probes 4 are made of copper, which has good conductivity, so that the first probes 3 and the second probes 4 correspond to the electrodes on the product. When the product is placed on the test board 6, it is easy for the electrodes on the product to contact the first probes 3 and the second probes 4, so that the test results are more accurate.

[0023] In this embodiment, refer to Figure 2 Sample tank 2 is made of insulating material, providing effective physical and electrostatic protection for the product.

[0024] In this embodiment, refer to Figure 2 The first probe 3 is made of a spring probe, and the second probe 4 is also made of a spring probe. When the product comes into contact with the first probe 3 and the second probe 4, the four electrodes on the product form a good flexible contact with the first probe 3 and the second probe 4, thus avoiding scratches on the product.

[0025] In this embodiment, refer to Figure 1 and Figure 2 A cover plate 5 is movably mounted on one edge of the test base 1 via a rotating shaft, so that the cover plate 5 and the test base 1 form a flip cover. A buckle 9 is provided on the side of the cover plate 5 away from the rotating shaft. There is a gap between the edge of the test plate 6 corresponding to the buckle 9 and the test base 1. The buckle 9 is fastened on the corresponding edge of the test plate 6, so that the cover plate 5 is fastened to the test base 1.

[0026] The cover plate 5 is equipped with a fixing mechanism, which is used to limit and stabilize the product. The fixing mechanism includes a movable base 7 and two limiting protrusions 8. The cover plate 5 has a movable groove 10. The movable base 7 is rotatably installed in the movable groove 10 through a rotating shaft. There is a gap between the movable base 7 and the movable groove 10, so that the movable base 7 can rotate within a small range along the rotation direction of the rotating shaft, so that the movable base 7 can achieve a small angle of rotation. The two limiting protrusions 8 are installed on the movable base 7. The two limiting protrusions 8 are set in a cuboid shape and are arranged in parallel.

[0027] Place the product on the test plate 6 with the screw side facing upwards, so that the screw part on the product is limited between the two limiting protrusions 8. By rotating the movable base 7, ensure that after the cover plate 5 is closed, the screw part is exactly embedded between the two limiting protrusions 8. The two limiting protrusions 8 directly abut against the bottom plane of the screw part and always maintain parallel contact to ensure good contact and uniform force.

[0028] The operating principle of this embodiment is as follows: During the testing process, the Kelvin test plug is first inserted into the testing system to open the testing channel. At the same time, the test base 1 is fixed. The buckle 9 fastened to the edge of the cover plate 5 is manually lifted and the cover plate 5 is opened. Then, the product is manually placed on the test plate 6. The four electrodes on the product are in contact with the corresponding first probe 3 and second probe 4. The cover plate 5 is then manually flipped so that the buckle 9 is fastened to the edge of the test plate 6. At the same time, the two limiting protrusions 8 limit and stabilize the screw part on the product. The cover plate 5 presses and fixes the product tightly on the test plate 6. The first probe 3 and second probe 4 are elastically contracted under pressure, so that the first probe 3 and second probe 4 form elastic contact when in contact with the product, achieving good contact. Press the test button to complete the test operation. The entire testing process is simple, efficient and convenient.

[0029] Testing can be completed quickly and efficiently by a single person, greatly saving labor and time costs, and improving testing efficiency by more than 10 times compared to traditional methods.
