Description

Technical Field

[0001] This utility model relates to the field of needle jig and needle plate technology, specifically a novel needle jig and needle plate. Background Technology

[0002] Traditional probe tray assembly methods involve stacking drilled probe trays together, inserting probes, and then separating each layer after all probes are inserted. Alignment pins are then used to fine-tune the inclination to prevent probes from escaping the tray. This type of product is primarily designed for high-end PCB testing fixtures, mostly for devices with a probe size smaller than 40µm. However, with the continuous development of PCB testing technology, the products being tested are becoming increasingly sophisticated.

[0003] As probes become increasingly smaller, manual insertion becomes increasingly difficult. Current technology uses inclined needle discs for operation, and all linear probe fixtures for 40µm and below operate with an inclined profile. This results in high needle loss rates, low operational efficiency, and high costs for manual insertion. Therefore, there is an urgent need for a new type of needle disc fixture to solve these technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a novel needle jig for threading, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel needle jig includes a first needle plate, a fine-tuning plate below the first needle plate, aluminum plates on both sides directly below the fine-tuning plate, a second needle plate below the aluminum plates, and a third needle plate directly below the second needle plate. Insertion holes are provided at both ends of the first needle plate, the fine-tuning plate, the second needle plate, and the third needle plate, and pins are provided in each insertion hole. Needle probes are inserted into each insertion hole on both sides of the pins.

[0007] As a preferred embodiment of this utility model, the first needle plate, the fine-tuning plate, the second needle plate, and the third needle plate are all the same size.

[0008] As a preferred embodiment of this invention, the fine-tuning plate can be moved left and right.

[0009] In a preferred embodiment of this invention, the number of needle probes is set to six.

[0010] In a preferred embodiment of this invention, all the sockets are through holes.

[0011] In a preferred embodiment of this invention, the bottom of the fine-tuning plate is in contact with the top of the aluminum plate, but the two are not connected.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model breaks through the traditional pin insertion method, improves efficiency by 30%, reduces losses by more than 25%, overcomes the shortcomings of automated production caused by the inclination of the pin plate, realizes CCD alignment testing, and reduces false tests.

[0014] 2. This utility model improves the manufacturing capability of traditional special test fixtures by using a linear probe structure design, increasing the minimum probe diameter from 40um to 20um. Attached Figure Description

[0020] Please see Figure 1-2 A novel needle jig includes a first needle plate 1, a fine-tuning plate 2 below the first needle plate 1, aluminum plates 5 on both sides directly below the fine-tuning plate 2, a second needle plate 3 below the aluminum plates 5, and a third needle plate 4 directly below the second needle plate 3. Insertion holes 8 are provided at both ends of the first needle plate 1, the fine-tuning plate 2, the second needle plate 3, and the third needle plate 4. Pins 7 are provided in each insertion hole 8, and needle probes 6 are inserted into each insertion hole 8 on both sides of the pins 7.

[0021] The first needle plate 1, the fine-tuning plate 2, the second needle plate 3, and the third needle plate 4 are all the same size.

[0022] Among them, the fine-tuning plate 2 can be moved left and right.

[0023] The number of needle probes 6 is set to six.

[0024] All of the 8 sockets are through holes.

[0025] The bottom of the fine-tuning plate 2 is in contact with the top of the aluminum plate 5, but the two are not connected.

[0026] The working principle and usage process of this utility model: The product sets probes according to the pins of the circuit board. By utilizing the layer stacking of the board, the wire probe 6 is effectively placed in the insertion holes 8 of the first pin plate 1, the fine-tuning plate 2, the second pin plate 3, and the third pin plate 4. The other end is in contact with the copper wire cross-section of the electrode surface. The other end of the copper wire on the electrode surface is connected to the electrical testing equipment through a contactor to achieve the testing effect. This breaks through the traditional pin insertion method, improves efficiency by 30%, and reduces losses by more than 25%. It also overcomes the shortcomings of the inability to automate production due to the slope of the pin plate, realizes CCD alignment testing, and reduces false tests. The product uses a linear probe structure design, which improves the manufacturing capability of traditional special test fixtures. The minimum probe diameter is increased from 40um to 20um.
