EMI Filtering Vs. Board Level Shielding
Electronic devices are a part of everyday life and hence it is essential that they have good quality PCBAs incorporated within for proper functioning. Often at device as well as PCB level, signals in the form of electromagnetic waves mix up which creates noise and may alter the functioning of the device. This interference must be removed. There are various...
Why Board Level Shielding is Necessary for System-in-package?
A system-in -a-package (SiP) or system-in-package has gained immense popularity in recent years, as it supports miniaturization and performance. It features several integrated packages, which are enclosed in carrier chips that are stacked using PoP. The SiPs are commonly used in electronic devices like digital music players, mobile phones, wearable devices, and so on. The demand for denser SiP packages...
Know What is EMC Testing
Electromagnetic interference or EMI is a known term, and it means the disturbance caused by mixing of signals coming from various nearby or connected devices. However, nowadays, electronic components and devices are designed to be EMC enabled. What does this mean? This means these devices can withstand EMC to a certain extent. Electromagnetic compatibility is the ability of an electronic...
Difference Between EMI and EMC : EMI vs EMC
Electromagnetic interference or EMI is the noise or disturbance caused by mixing of signals or waves generated from electrical and electronic devices. This may happen through conduction which is when two or more conductive devices come in contact with each other. It also happens through induction, wherein devices are distantly placed but their signals interfere with each other. This interference...
Know What is EMI Shielding Effectiveness Testing
A PCB is a core to any electronic device. It is usually designed for electromagnetic field interactions. At times, these electromagnetic interactions may interfere with the working of other circuits or devices close by the PCB. To avoid this, the PCB must be designed with electromagnetic compatibility. PCB designers have been following design guidelines to minimize EMI. However, that becomes...
Thermal Management within Board Level EMI Shielding
Speed, performance, cost, and portability have emerged as the high design parameters for PCB designers today. Densely populated printed circuit boards form the core of most electronic devices we use today. These boards have helped electronic OEMs to improve in terms of operational efficiencies; however, they have also introduced challenges in terms of effective thermal management and EMI shielding. If...
EMI Gaskets vs. Board Level Shielding Discussed
As digital electronic devices play a central role in our lives, electromagnetic interference is becoming a concern. Electronic OEMs are implementing various techniques to reduce the effects of EMI on devices. The first level of shielding is always performed on the printed circuit board, which is an integral part of any electronic device and second on the entire system using...
How to Reduce Electromagnetic Interference and Improve Electromagnetic Compatibility in Medical Devices
Electromagnetic compatibility (EMC) is a property of the device to maintain its compatibility in the electromagnetic environment. The EMC-compatible device is the one that doesn't emit electromagnetic waves to the level that interferes with the functioning of other devices. Most medical devices that we use today are made EMC compatible. This is because these devices are used for treatment and...
