Description

Technical Field

[0001] This utility model relates to the field of chip inspection technology, and in particular to a chip precision inspection instrument based on a die. Background Technology

[0002] Integrated circuits, also known as microcircuits, microchips, or wafers / chips, are a way to miniaturize circuits in electronics and are often manufactured on the surface of semiconductor wafers. After the chips are manufactured, they are inspected to check whether their dimensions comply with regulations. Generally, a measuring instrument is used to inspect the dimensions of sampled chips. This precision inspection instrument is used for inspecting the dimensions of chips.

[0003] When inspecting chip dimensions, ordinary measuring tools are inefficient. Furthermore, during the inspection process, the chip is in a free state and is prone to shaking or falling, which can damage the chip and hinder its safe deployment and use. Utility Model Content

[0004] The purpose of this invention is to provide a chip precision inspection device based on a card-type chip.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A chip inspection tool with a clip-on mechanism includes a tool with an inspection slot extending through the upper wall for placing a chip. A slider is movably connected within the inspection slot, and a scale mark is provided on the end wall of the tool near the slider.

[0007] Preferably, the end wall of the gauge near the scale mark is provided with a slide rail.

[0008] Preferably, a slide rail is movably connected inside the slide rail, and the top wall of the slide rail is fixedly connected to the slide plate.

[0009] Preferably, the slide rails are provided in three ways, with two slide rails arranged in parallel and one slide rail arranged perpendicular to the other. Each of the two parallel slide rails is provided with a sliding piece, and the other perpendicular slide rail is provided with three sliding pieces.

[0010] Preferably, the bottom wall of the fixture has an opening, and the front wall of the fixture has a through hole, with a horizontal piece snapped into the opening and through hole.

[0011] Preferably, the front wall and left wall of the inspection tool are provided with threaded openings at equal intervals, and a threaded rod is threadedly connected to the threaded opening. A rubber pad is adhered to the end wall of the threaded rod.

[0012] This utility model has at least the following beneficial effects:

[0013] The chip is placed in the inspection slot of the fixture, with the upper left corner of the chip close to and pressed against the upper left corner of the inspection slot. Then, the sliding piece in the inspection slot of the movable fixture is pressed against the front and right walls of the chip. The scale markings are then read to obtain the chip's size parameters. Throughout the measurement process, the chip is placed in the inspection slot without shaking or falling, making it safer and more stable. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a chip precision inspection instrument based on a chip insert:

[0022] like Figure 1-4 As shown, a chip precision inspection device includes a tool 1, a slot 2 penetrating the upper wall of the tool 1 for placing chips, a slider 6 movably connected in the slot 2, and a scale mark 4 on the end wall of the tool 1 near the slider 6.

[0023] The end wall of the gauge 1 near the scale mark 4 is provided with a slide 3, and a slide rail 5 is movably connected in the slide 3. The top wall of the slide rail 5 is fixedly connected to the slide piece 6.

[0024] There are three slides 3, two of which are parallel and perpendicular to the other slide 3. Each of the two parallel slides 3 has a sliding piece 6, and the other vertical slide 3 has three sliding pieces 6. The bottom wall of the gauge 1 has an opening 7 and the front wall of the gauge 1 has a through hole 8. A horizontal piece 9 is engaged in the opening 7 and the through hole 8.

[0025] The front and left walls of the gauge 1 are provided with threaded openings 10 at equal intervals. The threaded openings 10 are connected to threaded rods 11 by internal threads. A rubber pad 12 is attached to the end wall of the threaded rod 11.

[0026] Working principle:

[0027] The chip is placed in the inspection slot 2 of the inspection fixture 1, so that the upper left corner of the chip is close to and tightly attached to the upper left corner of the inspection slot 2 of the inspection fixture 1. Then, the slider 6 in the inspection slot 2 of the inspection fixture 1 is moved so that the slider 6 is attached to the front wall and right wall of the chip. Then, the scale mark 4 is read to obtain the size parameters of the chip. During the entire measurement process, the chip is placed in the inspection slot 2 without shaking or falling, which is safer and more stable.

[0028] There are three slides 3. Two slides 3 are set in parallel. The remaining slide 3 is perpendicular to the two parallel slides 3. The two sliders 6 at the two parallel slides 3 can slide up separately to fit tightly against the front wall of the chip. When the chip is short, the two sliders 6 can be used to fit tightly against the front wall of the chip to measure the size of the two chips separately.

[0029] The vertically set slide 3 has three sliders 6, which can be moved laterally and attached to the right wall of the shorter chip end wall respectively, for measuring multiple shorter chips.

[0030] The slide rail 5 and slide 3 are movable, used to move the slide rail 5 and slide piece 6, displacement slide piece 6, and adjustment slide piece 6. They are easy to use. The scale mark 4 is used to measure and read the chip size.

[0031] In the area in front of the through 8, the horizontal strip 9 is pulled and moved to open and close the opening 7. When the opening 7 is open, it is used to drop and discharge impurities. Or, when the opening 7 is open, when the chip is placed in the inspection slot 2, the outer convex lower end wall of the chip can convex down along the opening 7 to facilitate chip placement.

[0032] The threaded rod 11 at the threaded opening 10 rotates, shifts, and moves into the inspection slot 2, abutting against the side wall of the chip placed in the inspection slot 2, which serves to assist in bonding and abutting the chip. The rubber pad 12 is made of rubber and is used to buffer and protect the chip.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
