EMI/RFI shielding plays a vital role in a variety of industries. Let’s first cover some basic details about EMI/RFI shielding.
The electromagnetic waves generated by electronic devices may negatively affect other devices. These issues are called electromagnetic Interference (EMI) and radio frequency Interference (RFI). These interferences can create disturbances within electronics, which then degrade and reduce the effectiveness of the device circuitry.
We live in an increasingly electronic world, with millions of waves and signals floating through the air at any given moment. Also, as technology progresses, equipment has become more sensitive to electromagnetic interference. For this reason, effective EMI shielding is crucial to the reliability, safety and long-life of all electronics.
Shielding interferences is important for a number of industries. For example, EMI/RFI shielding is necessary in telecommunications because radio transmissions can disturb the reception of a signal if the signals are near the same frequency. Shielding may help prevent incorrect frequencies from interfering with a device’s functioning.
Hospital equipment must meet strict standards to prevent machinery from being affected by personal and other electronic devices. EMI/RFI shielding helps to make such protections possible.
Simply, EMI shielding separates a key component from outside EMI noise that may be interfering with the performance of the part. This method of solving EMI issues keeps noise out — or in — because it’s equally important that your equipment isn’t the one doing the interfering.
PVD coatings for EMI/RFI shielding
Physical vapor deposition is a vacuum-coating process that provides brilliant decorative finishes, with a high wear and corrosion tolerance. Due to its durability, hardness, heat and oxidation resistance, PVD is a popular choice in a variety of industries, including aerospace, automotive, medical/dental, sports/outdoors, home, telecommunications, gaming and weapons systems.
The deposition process for PVD is flexible, making it applicable for intricate parts. With interference shielding as the goal, deposition ensures a thin and thorough application. Only a few microns thick, PVD coatings also provide unparalleled durability and performance, and resistance to cracking, peeling and pitting. It’s because of this resilience that makes PVD coatings the perfect option for EMI/RFI shielding.
PVD coating has been around for decades. Its popularity is climbing because of its incredible durability and ability to decrease wear, friction and electromagnetic interference. PVD’s application possibilities are limited only by your imagination.
