Help boost signal-to-noise ratios in consumer electronics devices with industry-leading electrically conductive tapes.
You’re a problem solver. When electromagnetic interference (EMI) design challenges arise, you walk the line between maximizing device performance and controlling material costs. And with the expansion of 5G, solving EMI problems is more critical than ever. Today’s devices have flexible OLED displays, overlapping frequency bands and numerous RF components on the PCB. Consumers demand speed, functionality and reliability — without an increased price.
Help manage EMI and enhance signal integrity while saving space and cost with 3M™ Electrically Conductive Tapes. These “intelligent tapes” integrate powerful EMI shielding and grounding directly into your device and can be added late in the design process with virtually no electrical system redesign required. They can help control internal passive intermodulation (PIM) and boost signal-to-noise ratios in cell phones, tablets, augmented reality/virtual reality (AR/VR) devices and more. 3M brings decades of expertise in consumer electronics and materials science to help you solve EMI problems today and into the future.
PIM is a major source of signal noise in consumer electronics devices. It may result from poor contacts, dissimilar metal junctions, corrosion or other causes of nonlinear electronic behavior. Today’s RF devices employ large and increasing data densities, making PIM reduction exceptionally difficult.
Conductive adhesives from 3M provide excellent EMI shielding and stable contact resistance (< 0.1 Ω with a 1 cm2 contact area) to help you mitigate PIM and maximize signal integrity. This test configuration examines the power level of PIM associated with a junction in a PCB. The test substrate is a stainless-steel plate. Without shielding materials, −90 to −100 dBc of PIM is measured. But with a conductive tape from 3M applied at the grounding junction, PIM drops to −104 to −116 dBc. Harmonics generated are reduced even more dramatically in this test configuration.
A device is only as good as its display. Cutting-edge features mean little if the user can’t see what’s going on or can’t operate the touch panel. And with more products incorporating sophisticated OLEDs and microLEDs, display module grounding is essential to reliable device performance.
Help protect your displays by integrating industry-proven EMI materials into your design. Conductive adhesives from 3M provide excellent grounding between substrates and an EMI shielding performance of 60 dB or greater at specific frequencies. They can help reduce noise between the touch panel and LCD unit and are Z-conductive through the adhesive for reliable contact to small grounding areas.

Unify design and function
Today’s XR devices need to be designed with brand-defining aesthetics and lightweight wearability. Small contact areas bring EMI culprits closer to susceptible components, creating signal-to-noise issues. There are also small grounding areas and thin bond lines where traditional materials won’t suffice.
Don’t let condensed form factors threaten overall device performance. 3M™ Electrically Conductive Tapes bring grounding and shielding solutions with XYZ conductivity to designs with space constraints.
