Printed circuit boards (PCBs) are an integral part of electronic devices, and hence they demand accuracy in terms of functioning. Several manufacturing and assembly technologies have emerged in the past few decades, which have tremendously helped PCB manufacturers and assembly service providers improve their accuracy and increase their productivity. However, that is not enough, because designing a quality-driven and performance-oriented PCB is still a big challenge for many of these manufacturers. Among various challenges, electromagnetic interference (EMI) and electromagnetic compatibility (EMC) are two problem areas that PCB engineers have to take care of. To address these, they are offering various PCB EMI protection services. Why are these terms important? How are PCB manufacturers offering PCB EMI protection services to reduce EMI? This post discusses these topics in detail.
Electromagnetic interference, also referred to as radio-frequency interference (RFI), is a type of disturbance that may affect the performance of a circuit, sometimes even interfering with the device performance. This disturbance may be brought by an external source, and it may be in the form of electrostatic induction or conduction.
Electromagnetic compatibility is associated with the production, propagation, as well as acceptance of electromagnetic energy in a circuit, which may also interfere with its functioning. This interference may increase when two circuits work in unison, as a part of an application. As the demand for integrated circuits has increased, it is quite obvious that the sources will produce more electromagnetic energy. Owing to all these, it has become important for PCB designers to ensure the EMI and electromagnetic compatibility elements are reduced to a minimum. The next section discusses, how they experiment with design changes to reduce EMI and electromagnetic compatibility issues.
The following are a few proven design tips that have helped electronic engineers specializing in PCB EMI protection services to minimize EMI issues in a PCB.
Although these are the common practices for designing EMI-free PCBs, designers may also implement other design changes. If you are planning to design EMI-free PCBs for your next project, it is important that you approach reliable PCB assembly service providers like Twisted Traces who offer customized PCB EMI protection services. The company has a vast experience in designing and delivering EMI- and EMC-free PCBs for clients across critical service industries.
