Z-axis tape is made by 3M, and is used to bond two conductive surfaces together and allow a small (we’d say keep it under 100mA) current to flow through the tape. But here’s the cool part: its only conductive across the thickness of the tape itself, not along the length or width. Mindblowing, right? We took a macro shot of the tape above so you can see how it works. Its a regular adhesive tape with little chunks of conductive material every 0.1mm or so. The adhesive does the bonding, the little chunks do the conducting.
This tape goes great with our other interesting conductive materials, such as copper tape, ITO glass or plastic, conductive inks, etc. For a quick fun project we put some tape on a Gemma and Neopixels: remove the white cover first, then stick the circuit board onto the brown paper+tape. Cut out the shape around the circuit board, then carefully peel off the brown paper. Repeat for the neopixels. Make traces on a piece of paper and stick the Gemma and Neopixels down: ta-dah, paper circuit!
Each order comes with a strip of 2″ x 6″ tape. Its big enough you can use it for a bunch of projects. Just cut out the size you need and save the rest.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
