Product Description

JVCC CFL-5CA Copper Foil Tape is a 1 oz. rolled copper foil which provides excellent solderability and conformity. Used for RFI/EMI (electromagnetic interference/radio-frequency interference) shielding applications in the electrical/electronics industry (used to shield integrated circuit chips, cables and motors). CFL-5CA is coated with an acrylic adhesive which is uniformly dispersed with conductive spheres. Its conductive adhesive is ideal for printed circuit board modification, security-alarm circuit repairs, and prototype wiring-board layout and design. Also for cable wrapping to provide EMI/RFI shielding, seaming of EMI/RFI shielded rooms for electrical continuity, static charge draining and for surface contact to non-solderable materials (e.g. aluminum or plastics). The copper foil sheet resistivity is 0.003 Ohms/square inch. Its aggressive acrylic adhesive system creates a superior bond. Annealed and non-tarnishing, bright copper color. Flammability: File #130121, UL 510, Section 4. Can also be used for decorative arts & crafts projects. If not otherwise specified widths shown in dropdown are in inches. NOTES: Sizes shipped will typically be the tape industry standard metric-cut sizes, i.e. 24mm for each 1 inch of nominal tape width ordered (rolls are approximately 5% narrower than the nominal size). This product's actual size is 6.3mm wide. This tape is typically cut to width from log rolls so most sizes ship on a plain white core.

Great for some improvised connectors and connections.

I cut my fingers 3 times, although the cuts are small like paper cuts they do hurt!

This is good to help protect your plants from snails and slugs.

My project used 1" x 40" strips of conductive, carbon-impregnated, vinyl material for pressure sensors. I found the resistance of these strips to be inconsistent. Also, the resistance was much higher than I needed.
I ordered this tape with the hope that I could stick it on top of the strips and solve both my problems. I decided to try it because the tape claimed to have a conductive adhesive. I hoped that by simply taping the top side of a conductive vinyl strip, the copper would reduce the strips overall resistance and, hopefully, make the resistance consistent across the 100 strips used in my project. It would only work if the adhesive was conductive. It was! And it was very easy to apply.

I used this to line the outside of my container garden. It works great for keeping out slugs and snails, and much cheaper than buying the short strips marketed for that purpose. (make sure to wear gloves...the edges are sharp)

Well what can I say, it's copper tape. One side has excellent adhesion properties... And, on the other side copper... Great for arts and crafts, electronics, and hobbies. excellent for repairing broken traces on circuit boards.

Size Name: 1/4 in. x 36 yds. (6.3mm wide) Verified Purchase
I purchased this tape as an alternative to soldering together solar cells without tabs. I used it both as tabbing wire by cutting the tape into 1/32" strips and as the current bus connecting strings of cells together. The tape is particularly strong, even at 1/32nd inches and conducts well. Resistance is nominal. I just put my first panel in the sun and I get full voltage. Thus far the adhesion is withstanding the heat from direct sunlight well. It also plays well with other non-adhesive metallic tapes. I was running out of this tape, so the connected it with aluminum tape. Again, it conducts well with less practically no resistance when stringing together aluminum tape with this tape. Although I have some reservations regarding longevity of the adhesive, the technical specs look adequate for long-term use. Overall, I would recommend this product for those looking at stringing together solar cells who do not want to solder.

I purchased this foil in hopes that if I applied it to my garden boxes, it would deter slugs, which are a HUGE problem in damp Oregon. It totally did the trick. I strung the foil around the top of the wooden boxes twice, with a gap between of about a half an inch,using a staple gun to secure it more than just using the adhesive. With my fingers crossed, I kept a close eye on my garden beds and never saw a slug get in all year! Much better than wasting money on poisons!

This stuff is pretty cool. The adhesive is mediocre. Better than post-it, but not as good as Scotch tape. However, the adhesive is conductive. I was able to strap several AA batteries in series with this and resistance was very minimal. After assembling, I wrapped the entire assembly once in packing tape, and again over the terminals to protect the foil tape. Works like a champ.

For those of you who are electrically inclined, I did a quick back-of-the-envelope calculation for the resistance of this copper tape. The description says that it's 3.5 mils (.0035") thick, and of course it's 0.25" wide. That defines the cross-sectional area of the tape. The resistivity of copper is 16.78*10^-9 ohm-meters. Converting the inch measurements to metric and plugging into the standard formula, I get that the tape has a resistance of about 0.00075 ohms per linear inch, or 0.75 milliohms per linear inch.

What this means is that for each inch of tape, you add an incremental resistance of .00075 ohms. If you roll out 10 feet of the stuff (120"), the end-to-end resistance will be 0.09 ohms. If you run 1 amp through this tape length of 120", you will see a voltage drop of about .09 volts. (Voltage drop equal current times resistance, which is called "Ohm's Law" in the business.) Bear in mind that this is just for one of the conductors. If you use this tape for a 2-wire power system, the other piece of tape will experience the same current drain, so it, too, will have a .09 volt drop across it. This results in a total voltage drop at the end of 2*.09V = .18V.

You can easily calculate the resistance of other tape widths by decreasing the .00075 ohm figure by the ratio of the other tape width divided by this tape width of 0.25". For instance, 1" tape is 1.0"/0.25" = 4, so decrease the resistance by a factor of 4, resulting in .00019 ohms. Wider tape means less resistance, and therefore less voltage drop per length of the tape.

I purchased this copper foil tape to use for altered art projects-- namely soldered jewelry. I was very pleased with the results after using it for the first time. It adheres to glass like a dream, and seems to handle the flux & solder just fine.

The version I normally buy from a craft site is $5 for 3 yards. Obviously at about $13 for 36 yards, this is a MUCH better value. The huge roll size is a little tricky to work with for arts & crafts applications, but I'll probably end up transferring it to smaller empty rolls for convenience.

All in all, this product works just as well (if not better) than the more expensive name brand copper tape marketed toward hobbyists on jewelry supply & craft sites. I'm pretty sure I'll end up buying some other sizes from this seller as well.
