Bertech Copper Foil Conductive Tape, 0.6cm Wide x 36 Yards Long - Slug Repellent, EMI Shielding, Electrical, Guitar, and Soldering Repairs, RoHS and REACH Compliant

Good

I used this for a summer science program making light-up Father’s Day cards with kids. The copper tape worked well with other components for conducting current and each person’s card lit up! Note: Younger kids may need assistance removing the adhesive backing and placing the tape.

When you need to tape something, and you also need that tape to conduct electricity on both sides and through the tape itself, Kapton Tape comes through for you. Granted, there are not many situations where that is the case; but they do arise, and when you come across one, nothing else will do. I used this in conjunction with some wider copper tape to isolate the inside of my electric guitar from interference, and IT WORKED. It now no longer buzzes and hums like it used to! I would buy a thicker width if I was shielding another guitar; 1/4" turned out to be a bit too narrow for that application, but that's not the tape's fault. It sticks well and conducts well. Be aware that the edges of the tape are pretty sharp. You can easily cut yourself with this if you're not careful.

Used this to do a little project on an aging Cobalt Flux DDR pad, worked like a charm. The only reason I'm dropping a star is that no one makes a shorter roll. I don't want to buy 36 yards of this product; there should be a sampler pack of some sort so that I can get each of the different widths. 2" tape would have been more useful, but at a prohibitive $120, it's not worth it just to try it. P.S. For metal-to-metal DDR pad owners: Originally I tried just the tape, but that made an awful racket whenever I stepped and was quite distracting. Instead, I did a hybrid penny mod where you tape the underside of the penny with the copper tape with enough of it exposed on the sides to tape down with some regular electrical tape. I used 8 pennies per arrow in a square pattern, and 32 cents in pennies later, the pad is extremely responsive.

Copper tape in general is great. I've been taping this onto 3d-printed plastic parts and then soldering electronic components onto the tape. If the plastic has time to melt while soldering, the copper adheres to the plastic a little better. (fyi, using plastic as a soldering board is a terrible idea). Note that the tape is rated to 155F, so it will lose adhesion under high temperatures. Occasionally while soldering, in fact, the copper does seem to come off the plastic. I'm not sure how well the adhesion will hold up over time. I'll try this etching this tape to make real (low temperature) circuit boards soon and will hopefully report results here.
