Copper adhesive tape for EMI shielding

Only when the specific copper tape has an electrically conductive adhesive. 3M ET 1181 has conductive acrylic adhesive on smooth copper foil. In contrast, the listed 3M ET 1194 has a non-conductive adhesive. A conductive copper backing alone tells you nothing about conductivity through the adhesive layer. Match the contact point and required function to the data for the product you select.

With the right construction, copper adhesive tape can shield against electromagnetic interference and drain electrostatic charge. tesa 60537 combines a conductive copper backing and conductive acrylic adhesive for displays and other components. 3M ET 1181 is used for EMI shielding, static charge draining and cable wrapping. Whether shielding works in your assembly depends on the tape selected, the contact surface and the construction.

Copper foil is the backing material; electrical connection across the bonded surface also depends on the adhesive and its contact with the substrate. Both the foil and acrylic adhesive of 3M ET 1181 are electrically conductive. The same range also includes copper foil with non-conductive adhesive. Where a defined path through the adhesive layer is required, check the complete product construction and actual contact geometry rather than relying on the material name alone.

Describe the purpose of the connection, the intended product or required adhesive property, the contact surfaces and the geometry of the component. Add the required width, roll format or outline and the intended application step. Krückemeyer GmbH can cut suitable adhesive tapes and produce die-cut parts; whether the selected copper foil can be converted into the required format must be checked against the material and application. These details allow us to discuss a specific format with you.
