Copper Tape - 2" (50ft)

Copper tape has countless applications in electronics from creating low-profile traces for electrical components to RF-shielding and antenna-making. Copper tape is even used to join things together using solder, like the stained glass on Tiffany lamps.

This copper tape is adhesive-backed, a whopping 2" wide and comes in rolls of 50 feet. That's a lot of copper.

Thickness: 3 mil

Raw Copper Warning

This raw copper is not coated and can build up a layer of verdigris over time unless it is sealed.

    We use the tape as an antibiofouling measure on surface mooring instruments that are deployed for 6-month intervals in a coastal environment (an example is shown in Adhesive residue is difficult to remove after 6 month deployments, so we use vinyl pipe tape (right now we use Shurtape, available from Grainger) as an underlayment. For our mooring array, we typically use ~100 rolls/year, and it saves us a tremendous amount of time in post-deployment cleanup.

  • A little warning, here: I just opened my order of 4 rolls of this stuff, and the outgassing is overwhelming. I developed a headache after only about 4 minutes of handling them. Don't know what kind of solvent they use in manufacture, but unless you want your house/workshop/whatever to look like an episode of 'CSI' or 'Unsolved Mysteries' I would suggest leaving these out in an open-air environment for a while.

    Can you look into getting something like this and selling it by the foot?

    • Are you looking for wider sizes or the specific adhesive material?

      • Cjhazdroid / about 11 years ago / 1

        Wider sizes. A two inch width really doesnt give you much if you are looking to etch with this.

  • Sciguy / about 12 years ago / 1

    How easy would this be to cut with an x-acto knife?

  • Hmmm, I wonder if one could toner transfer a solder stencil on, etch, then stick on a pcb and apply solder? If so, it would offer an inexpensive alternative to purchasing a laser cut stencil.

    • Member #326474 / about 11 years ago / 1

      I don't see how it saves on having a having a stencil. Presumably the non-copper parts won't dissolve, so you won't get a stencil until you clean out all of the guck.

  • There's a video on YouTube of someone making a basic speaker out of this.

  • PalmTreesandPICs / about 12 years ago / 1

    Someone, please:

    1) Draw up a circuit thats 2x2 inches.

    2) Print such circuit on regular paper.

    3) Put a piece of this tape over the circuit drawing on said paper.

    4) Run the paper with added tape back through the printer(laser).

    5) Cut excess paper.

    6) Etch.

    7) come back here and post results.

    8) Hurry.

      I know this post is two years old, but i recently bought this tape and tried this^. It doesn't work. It just leaves smear marks, and you can scratch the remaining toner off with your fingernail. I wish it worked; i've been having trouble with the toner transfer method.

    • AtlWrk / about 12 years ago / 1

      Laser printers, by virtue of design, cannot print directly on conductive substrates. :(

      • PalmTreesandPICs / about 12 years ago / 1

        Ive read about people printing on Aluminum foil as a toner transfer medium.

        So, I still believe its worth a shot!

        • EvilGenius121 / about 12 years ago / 1

          link please???

          • PalmTreesandPICs / about 12 years ago / 1



            The first link leads to the second one.

            ... its not exactly a bullet proof source, but atleast i know im not the only one that thought about it!

            • DogP / about 12 years ago / 1

              I've been printing directly on flex circuit for years (single layer 0.5oz copper on polyimide)... it works fine with every laser printer I've used. I print on a piece of paper to align, cut a piece of flex circuit, remove the oxidization on the copper with a green scrubby pad, then use masking tape to hold it in place over the printed section. Then I feed it through, untape it, and etch like usual.

              I don't know how well this stuff would work though, since there's no backing. When you etch, the paper that you're stuck to will probably get weak and crumble. Then you've got a PCB held together only by the traces. :-P Also, if the thickness of the copper is 3 mil, that's about 2oz. copper... which won't be very friendly to etch (take a while, and difficult to get fine details).

      • mabey some plastic transparency or other medium would be better than paper.

      ** the first print with no tape is just to guarantee you possition the tape on the correct location on the paper.

  • HungryMaggot / about 12 years ago * / 1

    what is the thickness of this coppa tape

  • Check out the discussion over here, it's the same thing, just wider.

  • JerryGable / about 12 years ago / 1

    Do you know if the adhesive is conductive?

It's great for making things like dipole antennas, rf gasketing, other.

Very Useful Product

Used this copper tape to shield a new Pro-ject Carbon turntable and unshielded interconnects for a nephew living in an apartment. Although it did not eliminate all noise, it was very noticeable at about 10-12 db lower than pre-copper. And that's a lot! The weak spot is in the components themselves (probably the phono preamp) and no amount of copper shielding would have completely eliminated RFI and EMI interference.
Product recommended!

Good stuff

Bought to shield the GPS module. Worked great!

Excellent Product

High Quality heavy copper foil with nice conductive backing - excellent for RF shielding, VHF circuit layouts. Solders super easily. Excellent value.

Excellent product!

We use this tape for manufacturing electromagnetic antenna's.

Well, it's copper

...with a sticky backing. Cheap, copper, sticky. Use it for touch sensors. This is a lot of copper for the money. Good, pure, copper. I think I have enough copper for a few years. Copper. Mmmm...

Good Copper tape

Good pricing when you buy in bulk. Good adhesive on it too Overall good.
