Description

Technical Field

[0001] The utility model relates to the technical field of needle clamping tooling, in particular to a needle clamping tooling for chip or module testing. Background Art

[0002] In electronics, a chip is a way of miniaturizing circuits, mainly semiconductor devices, but also passive components, and is often manufactured on the surface of a semiconductor wafer. Another type of thick-film integrated circuit is a miniaturized circuit consisting of independent semiconductor devices and passive components integrated into a substrate or circuit board.

[0003] At present, after the chip is prepared, in order to ensure that it has sufficient functionality and safety, it is usually tested. Since the chip is small in size, a special fixture is needed to connect and fix it during the test. However, the existing chip test fixture is generally large in size, while the clamping area and the pin clamping area are small, which not only makes it inconvenient to carry, but also makes the installation of the chip more cumbersome during the test, affecting the efficiency of the test.

[0004] Therefore, a pin clamping tool for chip or module testing which is small in size and can be easily opened and closed is now designed to solve such defects. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a needle clamping tool for chip or module testing, which solves the problem that the existing chip test clamp is large in size and inconvenient to operate.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a needle clamping tool for chip or module testing, including a test base plate, the rear part between the two sides of the top of the test base plate is rotatably connected to a clamping frame through a rotating member, the lower parts of the two inner sides of the clamping frame are provided with arc guide grooves, the upper part of the test base plate is provided with an upper pressing plate, and the rear parts of both sides of the upper pressing plate are fixedly connected with driven rotating rods, and the driven rotating rods are slidably installed on the inner side of the arc guide groove.

[0007] Preferably, a retraction groove is provided at the top of the test base plate and below the upper pressing plate, a recovery plate is provided on the inner side of the retraction groove, and springs are fixedly connected to the front and rear parts of both sides of the bottom of the recovery plate, and the bottom end of the spring is fixedly connected to the bottom of the inner cavity of the retraction groove.

[0008] Preferably, a pinhole groove is provided on the outer periphery of the top of the recovery plate, and the pinhole groove extends to the lower part of the recovery plate.

[0009] Preferably, a test needle used in conjunction with the pinhole slot is fixedly connected to the bottom of the inner cavity of the retraction slot, and the top end of the test needle extends to the inner side of the pinhole slot.

[0010] Beneficial Effects

[0011] The utility model provides a needle clamping tool for chip or module testing. Compared with the existing technology, it has the following beneficial effects:

[0012] (1) The clamping tool for chip or module testing is installed by rotating a clamping frame on the top of the test base plate through a rotating part, and a driven rotating rod and an upper pressing plate are installed on the inner side of the clamping frame using an arc guide groove. The arrangement of these structures can directly open the upper pressing plate while prying the clamping frame, which is convenient for chip installation. After the clamping frame is pressed, it can also drive the upper pressing plate to fix the chip. It is easy to operate and has a small size, which meets the current use.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5The utility model provides a technical solution: a needle clamping tool for chip or module testing, including a test base plate 1, a clamping frame 2 is rotatably connected to the rear part between the two sides of the top of the test base plate 1 through a rotating member, arc guide grooves 3 are opened at the lower parts of the two inner sides of the clamping frame 2, an upper pressing plate 5 is arranged on the upper part of the test base plate 1, and the rear parts of the two sides of the upper pressing plate 5 are fixedly connected with driven rotating rods 4, and the driven rotating rods 4 are slidably installed on the inner sides of the arc guide grooves 3.

[0021] When in use, the snap-fitting frame 2 is bent backward by hand, and when the snap-fitting frame 2 is bent to a vertical position, it continues to be bent backward. At this time, the arc guide groove 3 will contact with the driven rotating rod 4 and pull the driven rotating rod 4. After the driven rotating rod 4 is pulled, the upper pressing plate 5 is also lifted up and separated from the test base plate 1. Subsequently, the chip is placed on the top of the recovery plate 7, and then the snap-fitting frame 2 is pulled forward again. First, the driven rotating rod 4 presses the upper pressing plate 5 and the test base plate 1 to re-dock and recombine with the test base plate 1 under the guidance of the arc guide groove 3. At this time, the chip is located between the upper pressing plate 5 and the test base plate 1.

[0022] Furthermore, a retraction groove 6 is provided at the top of the test base plate 1 and below the upper pressing plate 5, a recovery plate 7 is provided on the inner side of the retraction groove 6, and springs 8 are fixedly connected to the front and rear parts of both sides of the bottom of the recovery plate 7, and the bottom end of the spring 8 is fixedly connected to the bottom of the inner cavity of the retraction groove 6, a pinhole groove 9 is provided on the outer periphery of the top of the recovery plate 7, and the pinhole groove 9 extends to the lower part of the recovery plate 7, and a test needle 10 used in conjunction with the pinhole groove 9 is fixedly connected to the bottom of the inner cavity of the retraction groove 6, and the test needle 10 is connected to the test instrument with a connecting wire during testing, and the top end of the test needle 10 extends to the inner side of the pinhole groove 9.

[0023] After the clamping frame 2 is completely pressed forward to the limit position, the arc guide groove 3 will buckle the driven rotating rod 4, and the clamping frame 2 will also buckle the side of the upper pressing plate 5 so that the upper pressing plate 5 will not loosen. At the same time, due to the downward pressure of the upper pressing plate 5, the upper pressing plate 5 will also press the recovery plate 7 downward through the chip, so that the test needle 10 is exposed upward and contacts with the pin of the chip. At this time, the chip is tested, and the test needle 10 can guide data to the terminal for detection.

[0024] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
