Cinta Conductiva de Cobre 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 backed by a conductive adhesive, is a whopping 2" wide, and comes in rolls of 50 feet. That’s a lot of copper.
