Industry Information

EMI Gaskets

Gaskets are commonly associated with the automotive industry, as they are used to isolate two or more components to prevent them from interfering with each other. Electromagnetic interference gaskets serve a similar purpose. Electromagnetic gaskets, or EMI gaskets, prevent electromagnetic interference from leaking in or out of an enclosure through its gaps or seams. These components are utilized to enhance protection from electromagnetic interference among a group of sensitive components by isolating them. EMI gaskets are extensively used in both external and internal EMI shielding applications such as desktop computer housings, laptops, central processing units, and circuit board housings, and electrical automotive systems. As technology continues to advance and electronic equipment has evolved, radio frequencies have also become stronger and more able to break through seams, gaps, and cracks of various components. Therefore, EMI gaskets are becoming more frequently used for additional protection to prevent these radio waves from causing equipment failure or malfunction.

EMI gaskets fall under the category of components that provide electromagnetic field protection. They are similar in function to EMI enclosures, which are also referred to as faraday cages, which protect sensitive pieces of electronic equipment by surrounding the equipment and absorbing harmful electromagnetic frequencies. In order to successfully shield sensitive devices from electromagnetic interference as well as other components that may emit EMI, one must surround the equipment with an EMI enclosure that will efficiently absorb the harmful electromagnetic waves. There are many instances where EMI gaskets and EMI enclosures are paired together in order to effectively seal joints, seams, and gaps that may allow leakage of electromagnetic waves. Often times, the application of EMI gaskets is necessary in the overall structure of EMI enclosures.

EMI gaskets can come in a variety of materials. Such materials include conductive rubber materials like styrene butadiene rubber (SBR), nitrile, and silicone. The manufacturing of other EMI shielding metals such as Mu Metal® is often combined with the fabrication of EMI gaskets. EMI gaskets are commonly die cut with precisely designated holes or shapes, much like their non-EMI counterparts. The process of die cutting involves cutting or stamping two-dimensional parts out of flat sheets of a given material. Another process that is used to manufacture EMI gaskets is extrusion. The extrusion method involves extruding the gasket into gasket strips by heating EMI materials and forcing them through a precisely designed die, which provides the final shape. Another common process that manufacturers use is the bonding of extruded EMI materials to a magnetically conductive metal such as copper, aluminum, nickel, or any of their alloys. Manufacturers use this rubber to metal bonding process for the purpose of providing the product with a seal that is permanent, water-tight, and air-tight.

A new trend in the field of EMI gasket manufacturing is the development of plastics that can be electrically conductive. Plastics can be made conductive by either adding carbon nanotubes, steel fibers, or adding a conductive filler during the molding process. Conductive plastics have also been utilized in other applications such as electric grounding and electric switches. Up until recently, EMI gaskets have traditionally been made from conductive metals. Using conductive metals have made gaskets heavier, more expensive, and even less reliable. Therefore, many manufacturers have made the switch from metal to conductive plastic. Conductive plastic comes with quite a few advantages. They enable manufacturers to fabricate EMI gaskets that are more cost-efficient and reliable. However, conductive plastic comes at one main disadvantage. It is more sensitive to extreme temperatures, and prolonged exposure can lead it to melt or crack.

Since various materials and installation methods are available, it is important to consider which materials and methods are suitable for the desired application. Chemical compatibility is essential, so it is crucial to make note of what material should be used to construct the gasket relative to the environmental factors that the gasket will be exposed to, such as high or low temperatures, rain or wind, solvents, and other conditions. Installation of a gasket can involve the use of PSA's, epoxies, or fasteners, all of which could factor into the overall cost of the gasket. Gasket manufacturers will be willing to work with you in determining which options should be taken.

All electronic devices emit some amount of electromagnetic radiation. Sufficient amounts of EMI can be damaging for electronic devices if the equipment is exposed to it for a prolonged length of time. EMI gaskets are useful, and crucial in most cases, in preventing EMI radiation from interfering with other devices and components. EMI gaskets can block the gaps through which contaminants have the potential of leaking through. Although EMI gaskets differ from those used in automotive applications, gaskets are all fundamentally similar in that they protect all equipment from external or cross-interference from other components.
