Problems solved by technology
[0004] However, the above-mentioned existing technical solutions have the following defects: the method of fixing the metal sheet 11 on the substrate 1 of ABS material by screws 12 needs to punch holes on both the substrate 1 and the copper sheet, and it is necessary to pass very small screws 12 through them. It is installed in the corresponding holes on the substrate 1 and the copper sheet, so it takes a long time. In addition, compared with aluminum, which also has higher high-frequency electromagnetic shielding performance, the cost of copper is obviously higher.
To sum up, the existing solutions for making electromagnetic shielding strips have the disadvantages of low production efficiency and high production cost, which are far from meeting the existing market requirements for high production efficiency and low production cost.

Embodiment
[0048] refer to figure 2 and image 3 , is a production process of a shielding strip disclosed in the present invention, including a bottom plate processing process A, a glue printing process B and a metal sheet 11 bonding process C.
[0049] Specifically, the bottom plate processing technology A includes the following steps:
[0050] A1. Cutting: Cut the acrylic sheet 2 into the acrylic prototype 3 with a cutting machine according to the design requirements.
[0051]A2. Cutting: Use a laser engraving machine to cut the acrylic primary plate 3 in step A1 into a primary bead 4 according to the product size requirements. The cut bead 4 includes a working part 41 and an ear part 42. Specifically, the working part 41 is in the shape of a rectangular plate, and two ear parts 42 are provided on one side of the working part 41 .
[0052] A3. Punching holes: use a laser engraving machine to punch holes in the ear portion 42 of the preliminary bead 4 obtained in step A2, thereby fo...

The invention discloses a production process of a shielding strip, relates to the technical field of equipment or components shielding an electric field or a magnetic field, and aims to solve the problems of low production efficiency and high production cost in existing solutions for manufacturing electromagnetic shielding strips. The key points of the technical scheme are that it includes base plate processing process A, glue printing process B and metal sheet bonding process C. Among them, the base plate processing process A includes cutting, cutting, punching, trimming and polishing; the glue printing process B includes mold loading, silk screen printing and material transfer; the metal sheet bonding process C includes mold transfer, patching, drying and curing . The solution of bonding the aluminum foil to the acrylic bead bottom plate not only ensures the high-frequency electromagnetic shielding performance, but also speeds up the production efficiency of the shielding strip, which has the advantages of high production efficiency and low production cost.
Description
technical field [0001] The invention relates to the technical field of equipment or components shielding an electric field or a magnetic field, in particular to a production process of a shielding bar. Background technique [0002] In the current electronic equipment, certain components in it will generate electromagnetic waves, which will radiate and interfere with other parts of the electronic equipment and other electronic equipment outside the electronic equipment. This Electromagnetic Interference (EMI) / Radio Frequency Interference (RFI) can cause alteration or complete loss of important signals, causing the affected electronic equipment to malfunction or fail to function. In order to reduce the adverse effects of EMI / RFI, an electromagnetic wave shielding layer is often provided between two parts of the electronic circuit to absorb and reflect EMI / RFI energy. Such electromagnetic shielding generally takes the form of a wall or complete enclosure and is placed around t...
