EMI Shielded Enclosures

Electromagnetic interference, or EMI, can wreak havoc on electronics of all kinds. It’s something you don’t want to encounter in aerospace. EMI shielding protects electric equipment from interference for safety and better performance.

EMI happens because all electronic devices generate electromagnetic waves. If these waves clash, you have a problem on your hands. While many product manufacturers work to reduce EMI at the source through design choices, in many cases that is not quite enough, which is where custom EMI shielded enclosures come in.

Sources of EMI

If you think about all of the various electronic products that surround us at any given moment, you will quickly see why EMI is so widespread.

Ambient sources of EMI include signals and transmissions from televisions, radios, and satellite. Then there are solar magnetic storms, lightning, and the magnetic flux of the Earth itself. There’s utility power grid transmission line interference, transportation radar, telecommunications transmissions, and digital signals contributing, too.

Specific industries may encounter problems with EMI such as train signaling systems in railroad applications, or medical equipment sources in the health care industry.

There are sometimes intentional electromagnetic disturbances that are made to disrupt or disable equipment such as EMP cannons and high powered pulse devices. This is not a concern for your average citizen but can be a consideration in aerospace and defense industries.

The Anatomy of Custom EMI Shielded Enclosures

An EMI shielded enclosure is an extra layer of protection against EMI interference. EMI shields restrict electromagnetic waves from coming into, or out of, an electronic device.

Creating a custom EMI shielded enclosure is a matter of altering the electronic enclosure to make it act as a barrier against electromagnetic waves. Enclosures are typically best when they are manufactured out of conductive metal material, because that itself adds another element of protection against EMI, reflecting it back.

At New Age we provide EMI shielding through dip brazing, for industries that include military, aerospace, and electronics. Dip brazing not only offers EMI shielding, but it also provides full coverage and improved conductivity, creating strong bonds between all of the parts and pieces in a custom product like an EMI shielded enclosure.

Benefits of Custom EMI Shielding

EMI shielding is not an area where your business should skimp on quality or durability. Electromagnetic interference can cause big problems, from equipment failure to a potential loss of life when critical equipment fails as the result of interference. So, the first, and perhaps largest benefit of custom EMI shielding is the reassurance that your product will operate as intended, even in the face of EMI whether it is ambient or targeted.

Custom EMI shielding offers the added advantage of efficiency. Instead of trying to cram your product into something that does not quite fit, a custom solution works to protect your product efficiently and effectively, whether you need a one-piece shield, a fence and cover solution, or something entirely custom. Manufacturing is not a one size fits all industry, and your products will perform better when they are fitted with a custom enclosure.

EMI shielding works to save you money. Investing in protection against EMI is setting your business up so that you do not have to fix or replace products that are damaged through electromagnetic waves. It’s a proactive approach that will pay off.

Procuring Your Custom EMI Shielded Enclosure

No matter how large or how small your product is, our custom sheet metal fabrication allows us to create an enclosure that is perfectly dimensioned. We do all of our manufacturing and fabrication work in house, from start to finish, so as we fulfill your parts and product orders, the EMI shielding is just another step along the way. With New Age you don’t need to worry about multiple suppliers or manufacturers — we touch every part of your product while providing you with a single contact to get information and updates about your order.

Everything we do is based on the highest standards, as we are well acquainted with the rigorous requirements of industries like telecommunications and aerospace. We will work with you to understand how your product will be used, what regulations and requirements it needs to meet, and what level of EMI protection you require for the utmost in safety and performance. We can create custom EMI shielded enclosures that meet FCC protection levels, military protection levels, and levels suitable for any type of aerospace application.
