Silver Solution Ink Makes Faster Flexible Circuits

judgecorp writes "Silver-based compounds dissolved in ammonia could make finer and more flexible circuits, according to researchers at the University of Illinois. Existing inkjet based circuit printing systems use particles which are less predictable. The silver-based ink remains dissolved until the ammonia evaporates, and can be delivered through 100nm nozzles. In all senses, it's a better solution."

Corrosion?

There's a reason copper or gold is used in circuit boards despite silver being a far better conductor, how does this new solution avoid corrosion?
