Anisotropic conductive tape https://www.youtube.com/watch?v=0HZ35CyHVxQ https://www.youtube.com/watch?v=0HZ35CyHVxQ This is tape full of conductive microspheres that, as long as you use it right, conducts ONLY along the direction through the tape. Two contacts right next to each other will not conduct to each other, but two contacts one above the other will.
