Factors to Consider When Designing Board Level Shields
Board level shields have emerged as one of the popular choices for shielding PCBs from electromagnetic interference (EMI). These shields are applied onto PCBs in such a way that they mitigate EMI without disturbing the circuitry and components. Although these shields look simple, much consideration goes into designing them. This post discusses some important design considerations for board-level shields which...
PCB Design: Tips to Achieve EMC Compliance and Reduce EMI
Electromagnetic Compatibility (EMC) and Electromagnetic Interference (EMI) are crucial design considerations when designing Printed Circuit Boards (PCBs). EMC ensures that your device functions without interference from other devices in its shared operating environment, while EMI is electromagnetic energy that affects the functioning of the device. Both these properties must be taken into account when designing PCBs, as they can affect...
How PCB Designers Can Achieve Design Freedom with SnapShot® Board Level Shields
The demand for compact, dense, and feature-rich electronic devices is increasing every year. These devices feature printed circuit boards (PCBs), which are designed to meet their stringent performance requirements and comply with codes and rules laid by the Federal Communications Commission. The design process of PCB involves consideration of special features, finishing requirements, enclosure design, user interface, and component placement....
Removable Shielding Technologies for PCBs
You must be very creative today to effectively match the shielding solution to the size of the components and circuits on the PCB. Today's RF engineers are faced with new challenges when designing wireless communications devices. Modern cell phones have incorporated many features such as cameras, large multimedia displays, and multifrequency and multimode operation in smaller form factors than previously...

Electromagnetic Compatibility: Standards, Elements, and Solutions Discussed
Electrical devices operated in close proximity may sometimes interfere with one another. This interference may hamper the signals and create disturbances in their function. For instance, this type of interference may be observed when you keep your mobile phones or GSM sets near the television or a land phone. How to mitigate this type of interference? Well, this can be...
Know How to Reduce EMI in PCBs with Faraday Cage
Electricity and magnetism are closely associated as the flow of current in a device forms an electromagnetic field around it. Also, a rotating magnetic field produces electric signals. However, the signals coming from two or more electronic devices in close vicinity produce EMI or electromagnetic interference, by mixed signals in each other's spaces. This can disrupt the circuit and even...
