Description

Technical Field

[0001] This invention belongs to the field of chip testing technology, and in particular relates to a device for positioning chips in a carrier tape. Background Technology

[0002] In the field of chip manufacturing, the produced granular chips are usually packaged using long strip carrier tapes. The carrier tapes have multiple evenly arranged chip slots, in which the chips are stored and sealed with a sealing film.

[0003] When manufacturing electronic products that require chips, the process begins with a film-peeling device tearing open the sealing film on the chip carrier tape, exposing the chip inside the chip slot. Then, a feeding device transports the chip carrier tape to a chip testing unit. After the feeding device stops, the chip testing unit inspects the chips. When the chip testing unit detects a defective chip on the carrier tape, workers manually remove the defective chip and manually insert a good chip. This ensures that every chip on the carrier tape used in the production of electronic products is a good chip, thereby guaranteeing the production quality of the electronic products.

[0004] In existing chip testing devices, multiple probes contact the chip's pins one by one for testing. However, because there are gaps within the chip slot, the chip can shift within the slot, potentially causing the probes to lose contact with the pins. When this happens, the chip testing device cannot perform accurate testing, resulting in incorrect test results. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for positioning chips in a carrier tape, which ensures that the probe does not detach from the pin when in contact, thus guaranteeing the normal detection of the chip by the chip detection device.

[0006] This invention is implemented as follows: a device for positioning chips in a carrier tape. The carrier tape has multiple chip slots arranged at equal intervals, and chips are placed in the chip slots. The pins on both sides of the chips are arranged along the width direction of the carrier tape. The device includes a substrate, and multiple limiting plates arranged at equal intervals in sequence are fixed at the lower end of one side of the substrate. The front or back of the multiple limiting plates are located in the same plane. The multiple limiting plates are respectively inserted into the gaps between the chips in the multiple chip slots and the chips in the slots along the length direction of the carrier tape, and press the chips against the chip slots.

[0007] Specifically, the limiting plate has a wedge-shaped structure.

[0008] This invention utilizes multiple limiting plates at the lower end of the substrate to respectively engage with multiple chip slots and the gaps between the chips within them along the length of the carrier tape, thus pressing the chips firmly into the chip slots and positioning them within the chip slots. When the chip testing device tests the chip, multiple probes of the chip testing device contact multiple pins of the chip one by one, ensuring that the probes and pins do not lose contact, thereby ensuring that the chip testing device can perform normal testing on the chip.

[0014] Figure 5 yes Figure 4 Enlarged diagram of point A in the diagram. Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figures 1-5 As shown in the figure, this utility model provides a device for positioning chips in a carrier tape. The carrier tape 1 is provided with a plurality of chip slots 11 arranged at equal intervals. Chips 2 are disposed in the chip slots 11. The pins 13 on both sides of the chips 12 are arranged along the width direction of the carrier tape 1. The device includes a substrate 3. A plurality of limiting plates 31 arranged at equal intervals in sequence are fixed at the lower end of one side of the substrate 3. The front or back of the plurality of limiting plates 31 are located in the same plane. The plurality of limiting plates 31 are respectively inserted into the gaps 12 between the plurality of chip slots 11 and the chips 2 therein along the length direction of the carrier tape 1, and press the chips 2 against the chip slots 11.

[0017] Specifically, the limiting plate 31 has a wedge-shaped structure. This shape makes it easy for the limiting plate 31 to be inserted into the gap 12 between the chip slot 11 and the chip 2 inside it along the length direction of the carrier tape 1, and to press the chip 2 tightly against the chip slot 11.

[0018] This invention utilizes multiple limiting inserts 31 at the lower end of the substrate 3 to respectively engage with multiple chip slots 11 and the gaps between the chips 2 within them along the length of the carrier tape 1, thus pressing the chips 2 firmly into the chip slots 11 and positioning the chips 2 within the chip slots 11. When the chip detection device (not shown) detects the chip 2, multiple probes of the chip detection device contact multiple pins 21 of the chip 2 one by one, ensuring that the probes and pins 21 do not lose contact, thereby ensuring that the chip detection device can perform normal detection on the chip 2.

[0019] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
