Top Sources of Conducted EMI in Your PCB Layout and Proven Methods to Eliminate Them
Conducted Electromagnetic Interference (EMI) is an issue that arises when unwanted electrical noise travels along the conductors of a printed circuit board (PCB). These paths can include power and ground planes, signal traces, and various components. The presence of conducted EMI can cause disruptions in the normal operation of other components or circuits on the board, potentially leading to performance...
How Board Level Shields Contribute to Long Battery Life and Reduced Power Consumption in Electronic Devices
With the increasing requirement for performance-driven portable electronic devices, the need to reduce power consumption and extend battery life has become the utmost necessity. There are several ways of achieving the same and one of the most widely popular solutions is the use of board level electromagnetic interference (EMI) shields. Although these shields are specially made to protect sensitive electronic...
Know How Board Level Shields Help Protect Sensitive Data
Board level shields help protect the components and circuits on a PCB and control electromagnetic interference. This helps the board and final device to function normally, and which is why EMI shields are used by PCB designers and manufacturers. However, there are many other benefits of using good quality and flexible EMI shields. The role of board level shields goes...
How Radio Frequency Interference Impacts PCBs
Radio frequency interference (RFI) has existed way before the advent of electronics and digital signals. This is a type of interference that occurs with telephone lines, radios, and the old analog electrical devices used decades ago. This is caused due to the propagation of electrical signals coming from transmitters, phones, and amplifiers on the same frequency to the one you...
Know About EMI EMC Standards
Industry standards and regulations play an important role in setting manufacturing, testing, and other guidelines, laying a common ground for all manufacturers, devising safety pointers, and so on. This helps standardize the product making it easy for people to weight it against the set of guidelines or regulations when buying it. All of this applies to EMI shields as well....
3 Expert Tips for Cost-effective EMI Shielding
At the heart of every electronic device lies a printed circuit board. These boards are made of several electronic components that emit electromagnetic signals. These signals can cause interference with other devices and, as a result, negatively impact their performance. Several techniques have been implemented to mitigate this interference, and popular amongst all is the board level EMI shielding. The...
Mitigating Radiated EMI in a PCB Layouts
There are various types of EMI, out of which radiation EMI signals travel freely in air. Radiated emissions or electromagnetic waves of varied frequencies from a printed circuit board may accidentally clash with the waves in a peripheral device or surroundings. This results in noise which is referred to as EMI or electromagnetic interference. This also causes coupling with PCB...
Conquering Electromagnetic Interference with Copper EMI Shielding
Electronics manufacturers understand the importance of designing electromagnetic interference shielded enclosures for a circuit board. These enclosures are designed using various materials such as pre-tin plated steel, copper alloy 770/nickel silver, aluminum, and copper. Among these, copper is the most popular material used for making enclosures to attenuate magnetic and electrical waves in the printed circuit board. Although more expensive...
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...
