PCB board shielding is used to isolate metal between two spatial areas to control the induction and radiation of electric fields, magnetic fields, and electromagnetic waves. The shielding material absorbs, reflects, and cancels out energy to reduce interference, with different materials used based on frequency and wavelength considerations. An electromagnetic sealing gasket is used to fill gaps and prevent leakage, with various options available based on specific requirements.
This article discusses the importance of PCB layer stacking to control EMI emissions, highlighting the significance of power bus placement, electromagnetic shielding, and the design considerations for different layer counts to effectively reduce EMI interference.

Metal PCB boards, also known as thermal PCB or metal back PCB, are based on metal materials and used for the heat dissipation part of the board. The metal core provides better thermal conductivity, reducing operating temperature and improving overall performance and reliability of electronic devices. Metal PCBs are more compact and lightweight compared to traditional PCBs, making them ideal for applications where space and weight are critical factors. They also provide electromagnetic shielding and are suitable for applications in which electromagnetic interference needs to be minimized. Metal PCBs offer a range of benefits for various applications, including improved thermal management, reduced size and weight, and enhanced electrical performance. They have high mechanical strength, excellent processing performance, good heat dissipation, good magnetic conductivity, and high tensile modulus, and are widely used in applications involving cooling issues and the use of a large number of LEDs.
FPC connectors, or flexible printed circuit board connectors, are known for their flexibility and foldability, making them ideal for connecting in tight spaces with strong resistance to vibration and fracture. They are made of conductive metal film materials and consist of wires, protective layers, and connector seats. FPC connectors offer several advantages, including flexibility, electromagnetic shielding performance, high transmission rates, and low insertion and removal forces, making them widely used in high-speed transmission and frequent connection scenarios, especially in mobile communication devices. Their structure includes a rubber core, tongue, terminals, and welding pads, each serving specific functions. FPC connectors can be classified into different types based on structural characteristics, connection methods, PCB matching methods, insertion force, and the direction of the frame opening. They have good electrical performance, reducing signal interference and distortion during transmission, and can connect signal transmission between different electronic device boards.
