3M™ Tape CN3490 is an exceptionally thin and lightweight shielding solution made from a non-woven copper-nickel fabric. Its conformable nature allows it to fit easily into tight spaces and around irregular shapes. The acrylic conductive adhesive ensures a reliable ground path. This tape is an ideal choice for applications where minimizing weight and thickness is essential without sacrificing shielding effectiveness.
Primary Use: Shielding, grounding, and static dissipation in space-constrained electronic devices.
Ideal For: Shielding flexible circuits, I/O panels, and components inside mobile devices.
Manufacturing: Can be easily die-cut into complex shapes for precise application.
