Conductive EMI shielding tape

General description

We offer a range of conductive metal foil tapes that are suitable for many grounding and EMI shielding purposes. The range of tapes offered are based on three main foil types:

Aluminium
Copper
Tin plated copper

The copper and tinned copper tapes are readily solderable

Each type is available either with a conductive acrylic adhesive or without adhesive (plain foil). The adhesive backed versions can be wound on a release liner or self wound. They can all be supplied in widths up to 300mm, although more commonly supplied in widths of approximately 12, 25 and 50mm. All three tape types are very conformable allowing them to be applied to irregular or contoured surfaces. As such they are suitable for a wide range of EMI shielding and ESD control applications as outlined below:

Improving the EMI shielding of sheet metalwork seams/joints

Grounding ITO coated films for ESD protection of displays

Terminating shielded windows and display back shields

Creating shielded enclosures by lining plastic covers and enclosures

Shielding of static cable assemblies / conduit

General test and development work

We can supply pre-cut / formed components from these tapes so that they are easily assembled into or fitted into their intended location

In order to achieve the best possible electrical performance it is important that the surface it is to be applied to is not only clean but free of any oxidation /corrosion.

Electrically Conductive Tape Datasheets

ECT ASMR001 is a conductive adhesive transfer tape that combines both conductive pressure sensitive silicone and acrylic adhesives on opposite sides of a conductive woven mesh interlayer.

ECT CNFR001 is a nickel over copper plated PET based rip-stop fabric tape with a pressure sensitive conductive adhesive. It is both extremely flexible and durable with a very high resistance to tearing.
