Custom EMI Shielding Services

Electromagnetic Interference (EMI) can cause complications ranging from temporary disturbances to the complete failure of electronic devices, equipment, and interconnected systems.

What is EMI Shielding and Why Is It Important?

Electromagnetic interference shielding is the process of reducing the effects of an electromagnetic field by blocking it with barriers made of conductive or magnetic materials. Well-designed EMI shields will reflect, absorb, or redirect a wide range of electric or magnetic fields. Typically, EMI shielding is most effective when electrical devices and components are entirely isolated from their surroundings within a metal enclosure. This restricts the undesirable transfer of energy between mediums that must operate independently, such as an optical fiber to another nearby cable. In electronics and telecommunications, this interaction is called coupling, and it can cause a host of unwanted effects with potentially devastating consequences. The effectiveness of EMI shielding is determined by many factors such as:

  • Enclosure material
  • Thickness
  • Total volume/size of the shielded element
  • Type and frequency of the undesired field
  • The size, shape, and orientation of any apertures in the shielding

Today’s modern society would be impossible without the ability to control the effects of electromagnetic interference. For data centers, EMI shielding is obviously essential, but it is also critical in a diverse range of industries such as the medical, agricultural, and military. The effects of electromagnetic interference can be so devastating to a society that many consider the intentional use of the electromagnetic spectrum to cause damage an act of war.

Deep Coat’s EMI Shielding Services

Our team of researchers and developers have over 35 years of experience providing custom EMI reduction solutions to a wide range of customers, each with a unique and, at times, highly-specialized need. We have two patented approaches:

  1. Quad-fire – this method allows for a combination of up to four different layers of metal.
  2. Dual-fire – this method allows for two layers of metal in a single vacuum draw.

With our advanced equipment capable of performing the vacuum metalization process, we can accommodate single layer coatings as well as multiple layers of the same metal to meet all your EMI shielding needs.
