Description

Technical Field

[0001] The utility model belongs to the technical field of additive manufacturing electronics and relates to an observation device for detecting bubbles and impurities in a multilayer board. Background Art

[0002] Additive manufacturing electronics (AME), also known as 3D printed electronics or additive manufacturing, is an emerging manufacturing technology that allows the rapid manufacture of electronic components with complex micro-nano structures in the field of electronic engineering. This technology makes customization and single-piece small-batch production more economical and efficient by adding materials layer by layer. In the manufacturing process of AME multilayer boards, bonding and glue filling are key steps, which have a direct impact on the performance of the final product.

[0003] In the traditional multilayer board manufacturing process, the multilayer boards after bonding and filling need to be inspected for quality to ensure that there are no tiny bubbles and impurities that affect their electrical properties and mechanical stability. Currently, this inspection process is usually carried out under natural light, and the inspector needs to observe the multilayer board on a flat surface to identify possible defects. However, due to the fluidity of the adhesive and the structural characteristics of the multilayer board, observation using only natural light has the following limitations:

[0004] 1) The intensity and direction of natural light are uncontrollable, which may lead to inconsistent observation conditions at different times and environments.

[0005] 2) The surface of multilayer boards is prone to reflections under natural light, which can interfere with the inspector's identification of tiny bubbles and impurities.

[0006] 3) As the number of layers of multilayer boards increases, the internal structure becomes more complex and natural light is difficult to penetrate, making the detection of internal bubbles and impurities more difficult.

[0007] 4) Prolonged visual inspection can easily lead to visual fatigue, affecting inspection efficiency and accuracy.

[0008] Due to the above limitations, existing technologies face challenges in detecting tiny bubbles and impurities in multilayer boards, which not only affects production efficiency but may also cause product quality problems due to missed detection. Utility Model Content

[0042] The following is a description with reference to the accompanying drawings and a specific embodiment.

[0043] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0044] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in the subsequent drawings.

[0045] This embodiment describes in detail the structure and use of a bubble impurity observation device for AME multilayer boards. The prior art uses natural light on a work surface to observe the multilayer boards that have been glued and glued to see if there are tiny bubbles and impurities in them. The observation effect is different for multilayer boards with different layer thicknesses or under different natural conditions. When the top light is severe, it is even more difficult to observe. The utility model uses bottom light illumination, a shading device, and different shading sheets to adjust the bottom light intensity and color, so that bubbles and impurities in the multilayer boards after glueing and glueing can be more easily observed and removed, thereby improving the performance of the multilayer boards.

[0046] See also Figures 1 to 3 The AME multilayer board bubble impurity observation device described in this embodiment includes a light source 100 , a light shielding cover plate 200 , a semi-transparent sheet 300 and a clamping assembly 400 .

[0047] The device comprises a light source 100, specifically an LED lamp, located at the bottom of the viewing device for providing stable and adjustable illumination.

[0048] A shading cover plate 200 is disposed above the LED lamp 100, and an observation hole 201 is disposed on the shading cover plate 200. The diameter of the observation hole 201 is designed to be not less than the outer diameter of the AME multilayer board 500, ensuring that the multilayer board can be completely placed on the observation hole 201.

[0049] The light shielding cover 200 is used to prevent the light from the light source 100 from scattering to the area that does not need to be observed, thereby reducing light pollution and unnecessary illumination, making the observation more focused. The observation hole 201 on the light shielding cover 200 defines the area where the operator or the inspection equipment observes the AME multilayer board 500. This helps to concentrate the sight and illumination and improve the observation efficiency.

[0050] At least one semi-transparent sheet 300 is placed in the observation hole 201. The semi-transparent sheet 300 can be a PET film and / or a PI film. The light transmittance of the PET film is controlled between 80% and 95%, while the PI film is used to adjust the color of the light emitted by the LED light source 100, changing it from white light to brown light, so as to reduce reflection and improve the clarity of observation.

[0051] By increasing or decreasing the number of PET films and PI films, the light intensity through the observation hole 201 can be adjusted. For each additional PET film, the luminous flux of the light source 100 decreases by 20 lumens (lm), and for each additional PI film, the luminous flux decreases by 40 lm. The use of PI film can change the color of the LED light source from white light to brown light, which helps to reduce reflection and visual fatigue during observation.

[0052] The device also includes a clamping assembly 400 for clamping the AME multilayer board 500. The clamping assembly 400 is composed of a screw rod 410 and a nut 420. The screw rod 410 and the nut 420 are used together to stably fix the multilayer board. The AME multilayer board 500 is provided with a middle hole 501. The screw rod 410 and the middle hole 501 are detachably matched to facilitate the placement and removal of the multilayer board. The light shielding cover 200 also plays a certain role in structural stability. Together with the clamping assembly 400, it ensures the stability of the multilayer board 500 during the detection process.

[0053] When using:

[0054] First, the AME multilayer plate 500 is placed above the observation hole 201 of the light shielding cover plate 200 .

[0055] Next, according to the required light intensity and color, a suitable number of PET films and PI films are selected and placed in the observation hole 201 .

[0056] Then, the multilayer board is fixed on the device by the clamping assembly 400, and the screw 410 passes through the middle hole 501 and is tightened with the nut 420 to ensure that the multilayer board is stable and motionless during the detection process.

[0057] Finally, the LED light source 100 is turned on, and the operator observes the multilayer board 500 through the observation hole 201 on the light shielding cover to check whether there are bubbles and impurities.

[0058] Through the description of this embodiment, it can be seen that the AME multilayer board bubble impurity observation device of the utility model is reasonably designed, easy to operate, can adapt to different detection needs, and effectively improves the accuracy and efficiency of detection.
