Easy-to-use shielding, absorbing, grounding
and bonding technology for today’s electronics
The continuing trend toward designing electronic devices with smaller
enclosures, denser circuits and higher speeds has made managing
electromagnetic/radio frequency interference (EMI/RFI) and electrostatic
discharge (ESD) a growing challenge for electronics manufacturers.
3M can help you meet that challenge, with a variety of advanced shielding
and grounding solutions designed to help you speed assembly time…
reduce weight…save space…control costs…and give you more design
flexibility. Let 3M help you get connected!
