Background
In current electronic devices, certain components therein generate electromagnetic waves, which radiate and interfere with other parts of the electronic device and other electronic devices outside the electronic device. Such electromagnetic interference (EMI)/Radio Frequency Interference (RFI) may cause a change or complete loss of the vital signals, thereby causing the interfered electronic device to malfunction or fail to operate. To reduce the adverse effects of EMI/RFI, an electromagnetic wave shielding layer is often placed between two portions of an electronic circuit to absorb and reflect EMI/RFI energy. Such an electromagnetic wave shielding layer generally takes the form of a wall or a complete enclosure and is placed around the portion of the electronic circuit that generates the electromagnetic signal and around the portion of the electronic circuit that is susceptible to the electromagnetic signal.
In the prior art, components of an electronic circuit or Printed Circuit Board (PCB) are often enclosed by shields to confine EMI/RFI within its source and to isolate other devices proximate to the EMI/RFI source. But because of the many sources of leakage on the electronic device, such as gaps, vents, etc. where the different parts are joined. To effectively shield EMI/RFI at these locations, this is accomplished by placing electromagnetic shielding strips at these locations. Referring to fig. 1, the related art electromagnetic shielding strip includes a substrate 1 and a metal sheet 11, where the substrate 1 is made of ABS plastic, and the metal sheet 11 is a copper sheet. One side surface of the substrate 1 faces the slit 13, and the copper sheet is fixed to the other side surface of the substrate 1 by screws 12.
However, the above prior art solutions have the following drawbacks: the way of fixing the metal sheet 11 on the substrate 1 made of ABS material by the screws 12 requires to punch holes on both the substrate 1 and the copper sheet, and the very small screws 12 need to be inserted into the corresponding holes on the substrate 1 and the copper sheet, so the time consumption is longer, and in addition, the cost of copper is obviously higher compared with the aluminum which has higher high-frequency electromagnetic shielding performance. In conclusion, the existing scheme for manufacturing the electromagnetic shielding strip has the defects of low production efficiency and high production cost, and the requirements of the existing market on high production efficiency and low production cost can not be met.
