Getting Started with Copper Ink for Printed Circuits
Finding a cheaper alternative to silver for printed electronics has led a lot of engineers straight to copper ink. It's a pretty smart move when you look at the cost-to-performance ratio, especially now that the tech has matured enough to handle some of the old "deal-breaker" issues like oxidation. If you're working on flexible sensors, RFID tags, or just trying to prototype a circuit board without spending a fortune, switching over to copper-based solutions is likely on your radar. ...
