3M has created two new nickel and copper-plated, non-woven, conductive fabric tapes designed for grounding and EMI applications in devices such as mobile handhelds, digital still cameras, LCD televisions and other small consumer electronic products.
The metalized backing and conductive adhesive provide a conductive interface between components. Because the backing is a non-woven material, it is highly conformable. 3M Nickel and Copper-Plated Non-Woven, Conductive Fabric Tape CN3490 is coated with adhesive on one side while tape CN4490 is coated on both sides.
Tape CN4490 is only 50 microns thick, and tape CN3490 is 65 microns thick, making them thinner than standard conductive fabric tapes. They are repositionable for rework and faster assembly. There are fewer oxidation issues than is typical of metal insulations and no fingers susceptible to snagging and breaking. These tapes can be converted into sheets, slit rolls and die-cut parts.
3M serves original equipment manufacturers with OEM tapes, EMC and EMI-shielding products, antistatic masking tapes, heat shrink tubing and devices, liquid resins and adhesive transfers. 3M products are used for insulating wire harnesses, shielding against electromagnetic interference, protecting PCBs and electronic devices, and insulating electrical components.
