Description

Technical Field

[0001] The utility model relates to the technical field of integrated circuit testing, in particular to an integrated circuit testing socket. Background Art

[0002] An integrated circuit is a miniature electronic device or component that uses a certain process to interconnect the transistors, resistors, capacitors, inductors and other components and wiring required in a circuit. It is made on a small piece or several small pieces of semiconductor wafers or dielectric substrates, and then packaged in a tube shell to become a miniature structure with the required circuit function. The emergence of integrated circuit chips is a symbol of the rapid development of electronic technology. Integrated circuits often need to be tested before production or use.

[0003] After searching in the publication (announcement) number: CN218885986U, an integrated circuit test socket is disclosed, which relates to the field of integrated circuit testing technology, including an operating table, a lifting slot is provided at the top of the operating table, a lifting mechanism is provided inside the lifting slot, a base is fixedly connected to the inner bottom end of the lifting slot, and slide slots are provided at the top of the base near both sides. Two rotating motors are turned on the base, and the number of rotations of the rotating motors is controlled, thereby driving two positive and negative lead screws at one end of the rotating motor to rotate in the slide slot, so that the two threaded sliders on the positive and negative lead screws can move relative to each other. Under the active connection between the first movable part and the second movable part, the hinge rod is adjusted in angle, thereby adjusting the height of the test bench, which is conducive to driving the test bench to adjust to a fixed height under the rotation control of the rotating motor, so that the probe feet can detect the integrated circuit board under the fixed support of the support rod and the test top plate.

[0004] Although the above scheme realizes the height adjustment of the test bench and facilitates the contact detection between the probe pins and the circuit board, the wafer welding positions of different circuit boards are different, and the probe positions are immovable, which makes the applicability of the integrated circuit test base low. For this reason, we propose an integrated circuit test base. Utility Model Content

[0005] The main purpose of the utility model is to provide an integrated circuit test seat, which solves the problem that the wafer welding positions of different circuit boards are different and the probe positions are immovable, making the applicability of the integrated circuit test seat low by setting a lateral adjustment unit and a longitudinal adjustment unit.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An integrated circuit test socket comprises a main body unit, a lifting unit arranged in the main body unit, a lateral adjustment unit arranged above the lifting unit, and a longitudinal adjustment unit arranged on the side of the main body unit;

[0008] The horizontal adjustment unit includes a threaded shaft movably arranged in the lifting unit, a moving member installed on the circumferential side of the threaded shaft, a first driving motor installed at the input end of the threaded shaft, and a clamping member arranged above the moving member;

[0009] The longitudinal adjustment unit includes a C-shaped seat installed on the side of the main body unit, a fixed box installed on the inner top wall of the C-shaped seat, a lead screw movably arranged in the fixed box, a moving block installed on the circumferential side of the lead screw, a detection member arranged below the moving block, and a second driving motor installed at the input end of the lead screw.

[0010] Preferably, the main body unit includes a test box and a base installed at the bottom of the test box.

[0011] Preferably, the lifting unit includes an electric push cylinder installed on the inner bottom wall of the test box and a fixed seat installed at the telescopic end of the electric push cylinder.

[0012] Preferably, the clamping member includes a U-shaped seat installed on the top of the moving member, an electric telescopic rod installed on the inner side wall of the U-shaped seat, and a clamping plate installed at the telescopic end of the electric telescopic rod.

[0013] Preferably, the detection member includes a hydraulic telescopic rod installed at the bottom of the moving block and a probe installed at the telescopic end of the hydraulic telescopic rod.

[0014] Preferably, the longitudinal adjustment unit further includes a limit washer installed on the inner side wall of the fixed box, and the limit washer is sleeved on the circumferential side of the lead screw.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the utility model, through the arranged horizontal adjustment unit and longitudinal adjustment unit, when it is necessary to test an integrated circuit, first, the telescopic end of the electric push cylinder extends, so that the fixed seat extends out of the test box. Subsequently, the integrated circuit board is placed into the U-shaped seat. Then, the electric telescopic rod extends until the two oppositely arranged clamping plates are both in contact with the side wall of the integrated circuit board and then stops, thereby realizing the clamping and fixing before the integrated circuit test. After the clamping and fixing of the integrated circuit board are completed, the first driving motor drives the threaded shaft to rotate, so that the moving member can drive the clamping member to move horizontally along the threaded shaft. Subsequently, the second driving motor drives the lead screw to rotate, and the moving block drives the detection member to move longitudinally along the lead screw until the detection member stops directly above the wafer welding position of the integrated circuit board. Then, the telescopic end of the hydraulic telescopic rod extends until the probe contacts the wafer of the integrated circuit board and then stops, thereby realizing the adaptive movement of the probe foot position according to the positions of different circuit board wafers, and improving the applicability of the integrated circuit test base.
