Description

Technical Field

[0001] The utility model relates to the technical field of probe card detection, in particular to a fixing device for an integrated circuit probe card. Background Art

[0002] In traditional probe card detection and repair equipment, the operation method of fixing the P / C board is rather cumbersome. The specific steps are as follows:

[0003] (1) Use of the fixing jig: First, the fixing jig needs to be fixed on the marble tabletop of the machine according to the approximate size of the P / C board. Then, the four clamping screws on the jig are unscrewed, the P / C board is placed, and the clamping plate and the screws at both ends are screwed on again for preliminary fixing;

[0004] (2) Adjustment of position and angle: After preliminary fixing, the operator needs to turn on the observation equipment such as the CCD and microscope of the machine, and adjust the up and down position range of the P / C board according to the operation requirements;

[0005] (3) Confirmation of probe arrangement: After adjustment, the operator needs to confirm whether the probes on the P / C board are arranged in sequence through the observation equipment. If the probe arrangement is not intuitive, the P / C board needs to be further rotated and finely adjusted until the probes are aligned, and then the remaining two screws are fixed to complete the fixing operation.

[0006] This four-point fixing method not only increases the time for fixing the P / C board before operation, but also when adjusting the position and angle, the clamping plate is likely to scratch the POGO Ring on the PCB board. In addition, if the screw is not fixed properly, it may cause the PCB board to deform and affect the test result. Content of the Utility Model

[0007] The purpose of the utility model is to solve the defects existing in the prior art, and an integrated circuit probe card fixing device is proposed.

[0008] To achieve the above purpose, the utility model adopts the following technical scheme: An integrated circuit probe card fixing device, including a device main body, a fixing substrate is provided on the device main body, a metal reinforcement layer is fixedly connected to the fixing substrate, a P / C placement groove is arranged inside the metal reinforcement layer, a silica gel buckle is arranged on the metal reinforcement layer, a buckle fixator is fixedly connected to the bottom of the silica gel buckle, the bottom of the buckle fixator is rotationally connected to the metal reinforcement layer, and a fixing silica gel is fixedly connected to the bottom of the buckle fixator.

[0009] As a further description of the above technical scheme:

[0010] The P / C placement groove is a one-way push-in card slot.

[0011] As a further description of the above technical scheme:

[0012] The P / C placement slot is used to place the P / C board.

[0013] As a further description of the above technical solution:

[0014] The metal reinforcement layer prevents the device from deforming during use.

[0015] As a further description of the above technical solution:

[0016] There are two device bodies.

[0017] As a further description of the above technical solution:

[0018] The fixed substrate is used to be fixed on the operating machine table and measuring tool.

[0019] The utility model has the following beneficial effects:

[0020] 1. The traditional fixed fixture uses a four-point clamping plate fixing method, which increases the operation difficulty during the P / C fixing process. It is not conducive to the operator to fix while determining the position. Since the fixing force of the four screws is difficult to accurately control, once it exceeds the appropriate range, the clamping plate may scratch the PCB board. In contrast, the snap silicone fixing method adopted by the utility model simplifies the operation while minimizing the potential damage to the PCB board;

[0021] 2. In the utility model, the design of the snap fixer allows the snap to be fixed above the card slot. When performing the fixing operation, only need to rotate the snap to a specific angle, and then lower the snap and the silicone to achieve the fixing of the P / C board. This design not only ensures the safety of the operation, but also allows the operator to perform single-handed operation on the premise of ensuring safety, greatly improving the operation convenience. At the same time, when adjusting the position and angle of the P / C board, the operator can quickly and accurately locate through the reference lines on both sides of the device, further improving the work efficiency.

[0026] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Refer to Figure 1-2 , an embodiment provided by the present utility model: an integrated circuit probe card fixing device, including a device main body 1. There are two device main bodies 1, and the device main body 1 is the same as the original fixing jig. A fixing substrate 2 is provided on the device main body 1. The fixing substrate 2 on the device main body 1 is used to be fixed on the measuring tool of the operating machine table. A metal reinforcement layer 3 is fixedly connected to the fixing substrate 2. A P / C placement groove 4 is provided inside the metal reinforcement layer 3. A silicone buckle 5 is provided on the metal reinforcement layer 3. The bottom of the silicone buckle 5 is fixedly connected to a buckle holder 6. The bottom of the buckle holder 6 is rotatably connected to the metal reinforcement layer 3. The bottom of the buckle holder 6 is fixedly connected to a fixing silicone 7.

[0028] The fixing method of the device is changed from clamping plate fixing to silicone fixing, and the four-end screw for fixing the clamping plate is changed to a buckle-pulling type fixing. The clamping plate of the original fixing jig needs to first remove the clamping plate and then place the P / C. Now it is changed to a one-way push-in type card slot. The one-way push-in design simplifies the placement process of the P / C board, reduces the operation steps, and improves the work efficiency. The silicone buckle 5 fixes the fixing silicone 7 above the P / C placement groove 4 through the buckle holder 6 below it. As a soft material, silicone provides good friction when the fixing silicone 7 fixes the P / C board, and at the same time protects the surface of the PCB board from damage.

[0029] In order to prevent the device from deforming during use, the metal reinforcement layer 3 is used to reinforce the outer layer of the placement groove. The metal reinforcement layer 3 provides additional strength and rigidity.

[0030] Working principle: First, the operator aligns the P / C board with the P / C placement groove 4 on the device main body 1. The placement groove is designed as a one-way push-in type, so that the P / C board can be smoothly pushed into the groove along one direction, reducing the risk of scratching or damaging the PCB board during the placement process.

[0031] After the P / C board is placed in the groove, the operator uses the angle reference lines on both sides of the device or visual confirmation through the microscope CCD to adjust the position and angle of the P / C board to ensure its correct alignment with the probe;

[0032] After confirming that the position and angle of the P / C board are correct, the operator rotates the silicone buckle 5, which is connected to the metal reinforcement layer 3 through the buckle fixator 6 and can rotate. After rotating the buckle to a specific angle, the silicone buckle 5 presses down the fixing silicone 7, making it closely fit the edge of the P / C board, thus fixing the P / C board;

[0033] As a soft material, the fixing silicone 7 not only provides the necessary friction to keep the P / C board stable when fixing the P / C board, but also, due to its softness, can protect the surface of the PCB board from damage caused by pressure;

[0034] To ensure the stability of the device during use and prevent deformation, a metal reinforcement layer 3 is specially designed on the outer layer of the placement groove. This layer not only enhances the strength of the overall structure, but also provides additional protection to ensure the precise alignment of the P / C board and the durability of the device during the fixing and testing processes.

[0035] 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, for those skilled in the art, they 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.
