Why Choose 3M 1183 Copper Foil Tape?
3M 1183 combines tin-plated copper foil with conductive acrylic adhesive to support shielding and electrical contact applications. Compared with standard copper foil tape, its tin-plated surface helps resist oxidation and facilitates soldering. The release liner also supports precision converting and die-cutting.
Yousan can assist with adhesive tape sourcing, custom slitting, and precision die-cutting according to your drawings, dimensions, and application requirements.
Installation Guide
-
Prepare the surface: Clean the bonding area and remove dust, oil, moisture, and other contaminants.
-
Select the tape dimensions: Choose a suitable width or custom die-cut shape for the application.
-
Remove the liner: Expose the adhesive immediately before application.
-
Apply evenly: Position the tape carefully and press firmly to establish intimate contact.
-
Inspect the bond: Check for wrinkles, air gaps, loose edges, or incomplete contact.
-
Verify performance: Test electrical continuity, contact resistance, and shielding performance where required.
For soldering, grounding, or critical shielding applications, follow the applicable 3M technical documentation and the assembly’s engineering requirements.
Storage
Store the tape in its original packaging in a humidity-controlled environment at 10–27°C, with relative humidity below 75%. Protect it from direct sunlight, moisture, excessive heat, dust, and chemical contamination.
The 3M June 2021 data sheet specifies a five-year shelf life from the date of manufacture when stored under the stated conditions. Check the supplied product’s lot information and current documentation.
FAQ
1. What is 3M 1183 copper foil tape used for?
It is used for EMI/RFI shielding, grounding, static charge draining, cable wrapping, shielded-room seams, and electronic prototyping.
2. Is the adhesive electrically conductive?
Yes. 3M 1183 uses electrically conductive acrylic pressure-sensitive adhesive designed to provide an electrical path between the substrate and the copper foil backing.
3. What is the advantage of tin-plated copper foil?
Tin plating helps resist oxidation and corrosion and facilitates soldering to the foil backing.
4. Can 3M 1183 be soldered?
The tin-plated copper foil backing is solderable. Confirm that the soldering process and assembly conditions are suitable for the intended application.
5. Can 3M 1183 be die-cut?
Yes. The removable liner supports handling and converting into custom shapes and components.
6. What is the thickness of 3M 1183?
The June 2021 data sheet specifies a nominal backing thickness of 0.036 mm and total tape thickness of 0.068 ± 0.004 mm, excluding the liner.
7. What is its shielding effectiveness?
The June 2021 data sheet reports an average of 68 dB over 300 kHz–2.5 GHz under its specified test method. Actual performance varies with installation, contact quality, substrate, and frequency.
8. Is 3M 1183 suitable for outdoor use?
Its tin-plated backing helps resist oxidation and corrosion, but this does not guarantee suitability for every outdoor environment. Evaluate moisture, salt exposure, temperature, and the complete assembly.
9. Can 3M 1183 be supplied in custom sizes?
Standard configurations vary by market. Custom slitting and die-cutting can be evaluated based on the required dimensions, drawings, and order quantity.
