Abstract
Description
Technical Field
[0001] The utility model relates to chip detection related equipment, more specifically to a chip detection fixture. Background Art
[0002] A chip testing fixture is a device that can provide inspectors with a stable and easy-to-test testing device during chip testing. Existing chip testing fixtures only have basic clamping and rotation functions. In actual operation, chips may be damaged due to improper operation. When inspectors test chips, the densely packed pin contacts or capacitors on the chips can easily cause visual fatigue for the inspectors, increasing the difficulty of testing. Utility Model Content
[0003] The main technical problem solved by the utility model is to provide a chip detection fixture. The device can avoid chip damage caused by excessive clamping force while ensuring the chip is fixed. At the same time, the device can reduce the visual fatigue of the detection personnel, thereby achieving the purpose of improving the detection effect.
[0004] The purpose of the utility model is achieved through the following technical solutions:
[0005] A chip detection fixture comprises a base and a turntable rotatably mounted on the base, a clamping component is mounted on the turntable, and a shielding component for shielding the chip is mounted on the turntable.
[0006] As a further optimization of the technical solution, the bottom of the base of the chip detection fixture of the utility model is provided with an anti-slip pad.
[0007] As a further optimization of the technical solution, the clamping assembly described in the chip detection fixture of the utility model includes two clamping plates that are mirror-slidably installed in a slide groove set on a turntable, and a bidirectional threaded rod is rotatably installed on the turntable. The bidirectional threaded rod is threadedly connected to the two clamping plates at the same time, and gaskets are fixedly installed on the two clamping plates. Both ends of the bidirectional threaded rod are respectively provided with knobs for easy hand-held rotation.
[0008] As a further optimization of the technical solution, the bottom of the gasket described in the chip detection fixture of the utility model is provided with an extended support plate for supporting the chip, and a right-angle notch is provided in the middle position of the gasket.
[0009] As a further optimization of the technical solution, the gasket described in the chip detection fixture of the utility model is made of rubber material, a strip groove is provided on the gasket, and an elliptical groove is provided in the middle position of the strip groove.
[0010] As a further optimization of the technical solution, the shielding assembly described in the chip detection fixture of the utility model includes two N-shaped slideways symmetrically fixedly installed on the turntable, and a baffle slidably installed in a slide groove set on the N-shaped slideway.
[0011] The beneficial effects of the chip detection fixture of the utility model are:
[0012] 1. After the chip is fixed, due to the dense pin contacts or dense capacitors on the chip, the inspector is very likely to be dazzled and confused during the inspection, and it is also easy to cause visual fatigue to the inspector. To solve this problem, the inspector can slide the baffle to block the inspected position when inspecting row by row, thereby reducing the observation target. At the same time, the baffle can also be used as a reference to make the inspector more clear about the inspection position. The slide groove set on the N-shaped slide is open, so that the baffle can be installed immediately after use, which is more convenient.
[0013] 2. For the case where there are pins on the edge of the chip, the hard plastic clamping material is easy to cause the pins to bend, while the gasket is made of rubber material, which can avoid chip damage caused by excessive squeezing force. At the same time, the strip groove on the gasket can make the chip stably stuck in the strip groove, and the design of the elliptical groove can make the diagonal of the chip inserted into the elliptical groove, so as to fix the diagonal position of the chip and better protect the chip corner.

[0025] With such arrangement, the two-way threaded rod 31 is rotated by the knobs provided at both ends of the two-way threaded rod 31, so that the two clamping plates 32 provided in mirror image are moved toward the middle. When the distance between the two gaskets 33 is adapted to the width of the chip, the chip is placed on the extension support plates 331 on both sides, and then the two-way threaded rod 31 is slightly rotated so that the gaskets 33 clamp the chip, thereby achieving the purpose of fixing the chip position. The turntable 2 is rotatably mounted on the base 1, and the chip can be rotated by rotating the turntable 2, so that the chip can be observed from different angles.
[0026] A right-angle notch 332 is provided in the middle of the gasket 33, and the diagonal of the chip can be placed in the right-angle notch 332, so that the diagonal position of the chip can be fixed;
[0027] When the chip is fixed in position, due to the densely packed pin contacts or capacitors on the chip, the inspector is very likely to become dizzy and confused during inspection, and it is also easy to cause visual fatigue to the inspector. To solve this problem, when the inspector conducts inspection row by row, the sliding baffle 42 can be used to block the inspected position, thereby reducing the observation target. At the same time, the baffle 42 can also be used as a reference object to enable the inspector to more clearly understand the inspection position. The slide groove set on the N-shaped slide 41 is open, so that the baffle 42 can be installed immediately after use, which is more convenient.

[0029] With such a configuration, in the case of a chip with pins on the edge, the hard plastic clamping material can easily cause the pins to bend, while the gasket 33 is made of rubber material, which can avoid chip damage caused by excessive squeezing force. At the same time, the strip groove 333 provided on the gasket 33 can stably hold the chip in the strip groove 333, and the design of the elliptical groove 334 allows the diagonal part of the chip to be inserted into the elliptical groove 334, thereby fixing the diagonal position of the chip and better protecting the chip corner.
