EMI Shielding Design Considerations at the Heart of Medical Equipment Compliance and Performance

Download Whitepaper

As medical technologies evolve, EMI shielding becomes increasingly important. Interruption in medical device performance can be the difference between life and death. Without proper EMI shielding, medical devices, including life-support systems and essential monitoring equipment are vulnerable to signal noise, damage, or total functional impairment. A ventilator that doesn’t meet prescribed emission limits can have unfavorable consequences for other medical devices.

Therefore, EMI shielding, as a key component of engineering design, should be considered at all levels of design from the PCB layout to the enclosure. Engineers are faced with an array of shielding options to suit their needs at each design stage. Our experts will partner with you to identify the right solution to solve your Electromagnetic Compatibility challenges allowing you to optimize your design performance and compliance.

EMI Shielding : An underlying solution for precision and reliability in medical applications

Why is EMI shielding important?

All active electronic devices have the potential to emit electromagnetic radiation. EMI shielding products protect critical electronic components and systems from EM interference.

  • EMC compliance required by law/performance specifications.
  • EMC non-compliance causes system level redesign late in product development process.

Where is EMI shielding used?

EMI shielding gaskets are applied at the seams of an enclosure to establish a low resistance conductive path to block radiated emissions into and out of the enclosure.

  • Conductive gaskets/windows/vents at enclosure assembly level
  • Conductive gaskets for module assembly
  • Conductive gasket at board level cans at PCB level

How we address electromagnetic compatibility (EMC)?

Electromagnetic compatibility: Enables a device, equipment or system to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbance to anything in that environment.

Electromagnetic Interference is a form of pollution that can affect electronic equipment that is not protected from it. Think of it as Electromagnetic smog. EMI can cause effects ranging from annoying noises on your car radio to serious accidents when safety critical equipment is caused to malfunction.
