Description

Technical Field

[0001] This utility model relates to the field of conductor testing technology, specifically to a conductor surface cleanliness testing device. Background Technology

[0002] Conductor surface cleanliness testing mainly uses physical, chemical, or instrumental analysis methods to detect contaminants such as residual oil, dust, metal particles, and salt on the surface. The core objective is to ensure the conductor's conductivity, corrosion resistance, and the reliability of subsequent connections.

[0003] The detection method needs to be selected according to the type of pollutant, the required detection accuracy, and the conductor material. It is commonly divided into three categories: physical detection method, chemical detection method, and instrumental analysis method.

[0004] For testing the surface cleanliness of conductors before they leave the factory, physical testing methods are usually used, which are highly efficient.

[0005] Physical inspection method: Directly observe the surface for visible stains, scratches, or particles using the naked eye or an optical microscope (magnification 10-100x). Contact angle measurement: Measure the contact angle of a water droplet on a conductor surface using a contact angle meter. Clean surfaces have a small contact angle (usually <30°), while contaminated surfaces have an increased contact angle, allowing for quick identification of oil residue.

[0006] During inspection, it is necessary to observe different positions of the conductor. Existing microscopes usually require manually flipping the conductor during observation. Since the conductor (such as a chip) is small and difficult to handle, and fingers may block the conductor, affecting the inspection. Utility Model Content

[0007] The purpose of this invention is to provide a device for detecting the cleanliness of conductor surfaces in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a conductor surface cleanliness detection device, comprising:

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example 1:

[0026] Please see Figure 1-4 This utility model provides a technical solution: a conductor surface cleanliness testing device, including: an operating table 1, an inspection microscope 2, and a support plate 3;

[0027] The inspection microscope 2 is mounted on one side of the upper surface of the operating table 1, and one end of the support plate 3 is mounted on the other side of the upper surface of the operating table 1. The support plate 3 is located below the objective lens of the inspection microscope 2, and a mounting groove 4 is provided on the support plate 3. A flipping mechanism is provided at the mounting groove 4.

[0028] Analysis of the above content: The inspection microscope 2 adopts existing technology, and its structure and usage are also existing, so they will not be elaborated here (the figure is a schematic diagram, and the differences from the actual object do not affect the understanding of this solution). The conductor to be inspected (such as a chip) is placed on the flipping mechanism, and the flipping mechanism and conductor are manually flipped. The inspector can inspect different sides of the conductor based on the inspection microscope 2.

[0029] Example 2:

[0030] Please see Figure 1-4 This utility model provides a technical solution based on Embodiment 1: The supporting folding plate 3 includes an inclined lower plate and an upper horizontal plate connected to the left end of the inclined lower plate. The mounting groove 4 is opened at the left end of the upper horizontal plate, and the bottom end of the inclined lower plate is connected to the upper surface of the operating table 1. The flipping mechanism includes a rotating shaft 5 and a knob 6. The rotating shaft 5 passes through the front side of the upper horizontal plate and extends into the mounting groove 4. The knob 6 is connected to the front end of the rotating shaft 5, and a clamping mechanism is connected between the rear end of the rotating shaft 5 and the rear side inside the mounting groove 4.

[0031] Analysis of the above content: The handheld knob 6, based on the knob 6 and the rotating shaft 5, can rotate the clamping mechanism. The conductor is clamped on the clamping mechanism. By flipping, different sides of the conductor can be inspected, mainly checking the conductor's terminals and other positions.

[0032] Example 3:

[0033] Please see Figure 1-4 This utility model provides a technical solution based on Embodiment 2: The clamping mechanism includes a mounting plate 7 fixedly connected to the rear end of the rotating shaft 5 and a sliding column 9 movably inserted into the rear side of the upper horizontal plate. Fixed clamping heads 8 are connected to both ends of the rear sidewall of the mounting plate 7. A movable clamping head 12 is rotatably connected to the front end of the sliding column 9. A limiting ring 10 is connected to the rear end of the outer wall of the sliding column 9, and the limiting ring 10 is supported on the rear side of the upper horizontal plate. A support spring 11 is provided on the outer wall of the sliding column 9, with its front end connected to the outer wall of the sliding column 9 and its rear end supported on the upper horizontal plate. A concave groove 13 is formed inside the movable clamping head 12, and a limiting protrusion 14 matching the concave groove 13 is provided at the front end of the outer wall of the sliding column 9.

[0034] Analysis of the above: During clamping, the sliding column 9 is pulled backward, compressing the support spring 11. At the same time, the sliding column 9 drives the movable clamping head 12 and the limiting ring 10 to move backward, providing sufficient installation space for the conductor. The conductor is placed between the movable clamping head 12 and the fixed clamping head 8. Then, the elastic force of the support spring 11 pushes the sliding column 9, the movable clamping head 12, and the limiting ring 10 forward. The movable clamping head 12 and the fixed clamping head 8 clamp the conductor from three points, making the conductor stable.

[0035] The components, including the knob 6, the rotating shaft 5, the movable clamping head 12, the fixed clamping head 8, and the conductor, can be rotated as a whole.

[0036] After the conductor is inspected, it is removed. The support spring 11 continues to push the slide column 9, the movable clamping head 12, and the limit ring 10 forward. The limit ring 10 plays a limiting role to prevent the slide column 9 from falling off the upper horizontal plate.
