Part 2: What not to forget when manufacturing high frequency printed circuit boards – Electrical Signals and Electromagnetic Interference
Friday, June 2, 2023 - 12:23
When transmitting electrical signals through conductors on a printed circuit board (PCB), there can be electromagnetic field emissions that may interfere with other signals in the vicinity.
Electromagnetic interference (EMI) in relation to PCBs is a problem associated with the unwanted emission of electromagnetic energy from electronic components and conductors on the PCB, as well as the susceptibility of the PCB to external electromagnetic interference. The electromagnetic field from the surrounding environment or other electronic devices can impact the signal on the PCB, leading to erroneous readings or data transmission. Insufficient shielding of conductors or the lack of appropriate shielding materials can allow external electromagnetic interference to penetrate the traces on the PCB.
