The copper foil tape is used for RFI/EMI shielding application in the electrical and more. The tape consisting a copper foil backing coated with acrylic pressure sensitive adhesive. Copper tape has a non-conductive acrylic adhesive for grounding and RFI/EMI (radio-frequency interference/electromagnetic more. Copper tape refers to a thin strip of copper, often backed with adhesive. Copper tape can be found at most hardware and gardening stores and sometimes electronic stores. Copper tape is used to keep slugs and snails out of certain areas in gardens, potted plants, and trunks of fruit trees, and other trees and shrubs. The tape itself is made of thin pure copper so it’s extremely flexible and can take on nearly any shape. You can easily solder to it, and the tape itself can carry current just like a wire. On the back is an electrically conductive adhesive. The adhesive can’t carry significant current but it is very handy for sensing applications where you don’t want to solder the copper tape. Copper foil tape consists of a 1 ounce rolled copper foil backing and an electrically conductive, pressure-sensitive acrylic adhesive. This tape is supplied on a removable liner for easy handling and die-cutting. It has excellent solder ability. Copper foil tape is typically used as an EMI / RFI shielding tape for applications in the electronics industry such as static charge draining, seaming shielded rooms, cable wrapping, and surface contact to non-solder able materials. Many factors determine true shielding effectiveness of a shielding tape, including type and thickness of foil, adhesive type, intimacy of contact, smoothness of application surface, frequency of the EMI signal, and more. An electrically conductive adhesive is a glue that is primarily used for electronics. The electric conductivity is caused by a component that makes ca. 80% of the total mass of an electrically conductive adhesive. Copper foil tape comes in two forms– with conductive adhesive and with non-conductive adhesive. Copper tape with non-conductive adhesive is more common. For example you can get it at your local hardware store in the gardening section– it’s used to keep snails and slugs out of gardens.
