The Benefits of Using a Board Level Shield for EMI/EMC Protection

By abbas 6 Min Read


If you’ve ever had an electrical device malfunction due to EMI and EMC (electromagnetic interference and electromagnetic compatibility) issues, then you know how frustrating it can be. You’re trying to run a business or manage a project and your tech isn’t working like it should. Luckily, there’s an easy solution that can help protect your devices from outside interference: installing a board level shield! A board level shield creates a barrier between the device and the outside environment. It works by absorbing any unwanted radiations before they have time to disrupt your equipment’s normal operations.

Board Level Shield for EMI/EMC Protection

Board level shields are an effective way to control EMI/EMC problems. They’re thin, flexible materials that can be placed on the back of a device. This allows for maximum protection by providing a barrier between sensitive components and interfering signals (like radio waves).

Board level shields can also help prevent damage from electrostatic discharge (ESD) events, which occur when static electricity builds up in your body or on other items that touch it. When this happens, voltage surges travel along conductive surfaces like metal housings or circuit boards until they reach something that conducts electricity better than air does–such as your motherboard! If these surges reach high enough levels, they could damage sensitive components like microprocessors or memory chips

Gain Control over EMI/EMC Problems

EMI/EMC problems can be a major headache for your company. If you don’t have a board level shield to protect against EMI/EMC interference, then it’s possible that some of your devices will stop working properly. This can lead to lost productivity and even higher costs down the road if you have to replace parts that were damaged by EMI/EMC interference.

Fortunately, there are ways to avoid these problems by using a board level shield as part of your overall EMI/EMC protection strategy. A good example would be installing one on each side of an enclosure so that signals coming into or going out of the box are blocked before reaching any sensitive components inside the enclosure (like CPUs). The best thing about this type of solution is that it works regardless if those signals get disrupted because they’re being emitted from within or outside of their intended target area–they’ll still get blocked either way!

Installing a Board Level Shield

Installing a board level shield is simple, but there are some things you need to do to make sure that it’s working properly.

  • Make sure the shield is installed correctly. The metal plate should be placed between your device and its enclosure, not on top of it or inside it. If you have an older device with no room for a shield in its enclosure, try using double sided tape instead of screws or glue to secure it in place–this will allow you to remove and replace your board level shields as necessary without damaging any parts of your circuit boards.
  • Test for EMI leaks by powering off all electrical equipment in your lab (including computers) before running tests with an EMI test meter, which can detect electromagnetic interference from nearby electronics like cell phones and computers if they’re still powered on during testing time periods where there should be no interference present at all levels within each room/area being tested at once when performing these types of tests!”

A board level shield creates a barrier between the device and the outside environment.

A board level shield is a barrier between the device and the outside environment. It prevents electromagnetic interference (EMI) from reaching your product, which can cause problems with its performance or even damage it. A board level shield can be made from a variety of materials, including metal, plastic and glass fiber-reinforced polyester (FRP). It may also be installed in different ways depending on what kind of material you choose for construction:

  • Metal shields are usually fastened directly onto the surface of printed circuit boards (PCBs). This type of installation provides excellent protection against EMI but does not allow for easy access for maintenance tasks such as replacing components within an enclosure or repairing damaged circuitry within a unit’s housing.
  • Plastic shields are attached to PCBs using adhesive tape strips called “bond wires” that secure these thin pieces over exposed edges where electrical signals pass through into connectors located around perimeters where they’re exposed outside enclosures’ walls due to openings left behind by removed components from previous repairs needed elsewhere inside enclosures.’


A board level shield is a great way to reduce electromagnetic interference (EMI) and electromagnetic compatibility (EMC) problems. The shield can be installed in any device that needs protection from outside interference, including computers, smartphones and other consumer electronics.
