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 non-branded plain white cores.

I was sceptical about the 'conductive adhesive', but...

By W. Klaila on February 9, 2008

Size: 1/4 in. x 36 yds. (6.3mm wide)

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.

slug barrier

By Rick on June 17, 2010

Size: 1 in. x 36 yds. (25.4mm wide) Verified Purchase

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)

It's copper, it's tape, and it works.

By The Overbobb on May 12, 2009

Size: 1/4 in. x 36 yds. (6.3mm wide)

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.

Say goodbye to slugs

By JayneDoah on December 8, 2011

Size: 1/4 in. x 36 yds. (6.3mm wide) Verified Purchase

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! UPDATE: The tape lasted well for at least 2 or 3 seasons. It was still on the boxes (again, with the help of the staples) when we moved out of the house.

Resistance of 1/4" wide copper tape

By RetiredEE on March 27, 2012

Size: 1/4 in. x 36 yds. (6.3mm wide) Verified Purchase

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.

Works Well

By Christopher Lumsargis on August 22, 2009

Size: 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.

Slug-Be-Gone! This is like magic.

By Jeff Michelson on May 18, 2011

Size: 2 in. x 36 yds. (50.8mm wide) Verified Purchase

Slugs here in the Pacific North West are a real problem. As soon as I get my starts in the ground the little slimmy suckers are all over. I've had entire basil, lettuce, and kale starts nearly gone 24 hours later.

I didn't want to use poisons, and going out every night to pick the slugs out by hand got old pretty quick.

This stuff isn't cheap, but it does seem to work. I lined the top portion of my raised boxes in the afternoon, and then went out after dark to see the results. I watched a couple slugs over the course of 20 minutes make several attempts to cross the 2" barrier, and never got their heads past the first 1/4" of tape.

Installation is a bit tricky if you want to make this look nice. The tape is easy to crinkle and you only get one shot with it. The tape is easy to remove if you make mistakes. It does add a nice visual effect to whatever you tape this onto.
