10/28/2023 0 Comments Emi emc engineer interview questions![]() Does your product’s radiation disturb other devices present nearby? Whether it is within the set standards? Are the relevant EMI standards such as IPC CISPR standards achieved? In this article, we will cover the PCB design guidelines using which EMI and EMC can be controlled/avoided. This is the reason why EMI/EMC study and analysis are important. So, any product having wires/traces and operating at high frequency has the tendency to radiate radio waves. Thus, it is highly important to measure electromagnetic radiation and control these radiations. There are international standards that limit the level of emissions. These EMI radiations interfere with other devices present in the vicinity. At high frequencies depending on the length of the interconnects and the current carried by the conductors, the interconnects tend to act as antennas, resulting in EMI. It is not possible to get rid of EMI/EMC completely, but we can surely curate our PCB design services to make them less vulnerable to EMI/EMC effects.Īn electronic system consists of printed circuit boards (PCBs), integrated chips, interconnect, and I/O cables. ![]() It would be very irking if a person walking down the sidewalk talking on their cell phone caused interference to someone else’s audio device. As consumer electronics is in high demand, the effects of EMI must be taken into consideration. This is to avoid interference of mobile and electronic device signals with the plane’s navigational signals. We can also experience this when we board a plane and are asked to switch off the electronic devices by the crew. If you turn on your radio set and TV simultaneously, you will experience the noisy disturbance from TV interfering with the radio signal and vice-versa. ![]()
