All Snippets and Content Compliments of 3M.
Key Takeaways
-
3M offers worldwide leadership from decades of expertise in materials technology and EMI/RFI challenges including dynamic EMI shielding and grounding
-
3M offers multiple tape types including conductive adhesives, carriers, and conductive fillers providing various flexibility, conformability, adhesion, temperature and shelf life while offering moisture resistant, low outgassing, no-nickel or non-magnetic conductive options along with various axis (XYZ) electrically conductive fabric, copper foil, and adhesive transfer tapes
-
3M’s EMI/RFI solutions are known for boosting signal-to-noise ratios (SNR) in consumer electronics, to helping improve antenna signal integrity on 5G towers, and even grounding displays in automotive, industrial, and connected products
-
Minimize EMI noise and crosstalk, improve signal-to-noise ratios, obtaining high-performing reliable materials while being more cost effective by using quick and easy peel-and-stick solutions
-
3M offers support and key contacts, along with product support from DigiKey
-
DigiKey offers low (if any) minimum order quantities, short lead times, and multiple sizes with fast and reliable service
Frequently Asked Questions
Can any of these tapes be used to hold welding assemblies together, and then welded on?
- No, the tapes aren’t used to hold assemblies together.
Do you have examples of how the tape can be used to create a shielding can? The tape must be grounded around the perimeter of the area but not short against components.
- Yes, you can see a demo video here: https://www.3m.com/3M/en_US/consumer-electronics-us/applications/emi-management/
Great presentation. I would also be interested in seeing another webinar about RF absorber solutions, particularly thin RF absorbers with/without shielding.
- Thank you for the great feedback. We are launching two new absorbers in 2023. One is for high temperatures and the other is for the 5G band.
Can you provide a detail and functional use cases of the AB6000HF series tape?
- We will follow up with you after the webinar. The AB6000HF series is for EMI absorbing vs EMI shielding and grounding.
Can the 9703 product be used in surface mount applications in place of solder?
- No, 9703 doesn’t meet the requirements to replace soldering. It’s for general flex and interconnect applications.
When design for cable (twisted pairs) EMI shielding, what’s the best practice of percentage of unshielded cable in either ends of the cable?
- The best practice is 100% covered for high frequencies.
Will this work on a small cable for RFI?
- Yes. The fabric tape such as 5113sft is a great solution for wrapping that cable.
Does 3m offer any anisotropic conductive elastomeric pads. These are thin, compliant interconnect layers that conduct in Z axis only. Typically used for ITO contact to circuit boards. I need non-adhesive pad, ~0.4mm thick x 50mm x 50mm for IC testing.
- We supply anisotropic conductive adhesives (9703) and Conductive Films (9703) these will be much thinner… that the .4mm pad.
Can you send the URL for the video on RF Shielding Can Replacement, please?
- Yes, you can find it here: https://www.3m.com/3M/en_US/consumer-electronics-us/applications/emi-management/
