What is an EMI gasket?
An EMI gasket is a special conductive material formed so as to provide an electromagnetic seal in an electromechanical system. An EMI seal is an allusion to keeping radio frequency signals from being transferred across a boundary, analogous to a water proofing seal in a waterproof product. An EMI gasket creates an electromagnetic interconnection between mechanical parts of a system to create a continuous conductive shield. Such a shield can be referred to as a Faraday's Cage.
EMI gaskets, also known as EMI shielding gaskets, come in various styles, including O-Rings that fit in the conductive mating joint between shields, shields and PCBs, or even in mechanical body shells of products. They can also come in foam, sheet, and mesh forms, and are available in different effectiveness at different frequency ranges, anywhere from 10kHz up to greater than 20GHz. They have different mechanical properties, from being elastomeric, conductive rubber or even metallic flanges.
How do EMI gaskets work?
EMI gaskets require compressive force to function properly. Compression loading will change a gasket's shape, with typical compression being 30-40% for many gaskets to allow them to work properly. This is called EMI gasket compression set, and the gasket must be able to undergo regular compression and release during enclosure door closing and opening. EMI gaskets must be able to still retain this compressibility even after extended compression and multiple release and re-compression cycling. They must also be very stable, not changing their electromechanical properties over their life expectancy.
Gaskets can have pressure sensitive adhesion. They can also be tube-like and sit in the groove in the mechanical interface, held in place by friction. They can be directly soldered or glued to the associated PCB or mechanical device. Some gaskets are connected by metal spring-like structures, whose metal surfaces form an electrical connection. Because radio frequencies must have physical holes that are greater than a fraction of the wavelength to start coupling through, most shields save materials, weight, and cost by being mesh or having small hole patterns.
An important characteristic of an EMI shield is its ability to attenuate unwanted EMI. Improved isolation leads to lower radiated emissions from a device and lower susceptibility of that device to spurious behavior because this interference causes the circuit to stop working (for example blocking effects in receivers). EMI gaskets can improve a shielding solution's ability to block unwanted RF interference.
