The company NovaCentrix and the Eurecat technology centre (a member of Tecnio) have unveiled a printed keyboard with circuitry and hybridized LEDs that make it possible to control audio and video playlists using an electronic device. The innovation was presented at the Graphispag trade fair, which is taking place in Barcelona until 29 March.

The demonstrator was created using a new flexible-soldering process known as photonic soldering, which “only heats the soldered part and does not affect the surface beneath”, according to Paul Lacharmoise, the director of Eurecat’s Functional Printing and Embedded Devices Unit.

“This new technique lowers production costs, as it makes it possible to solder components in a matter of milliseconds without the need for conductive paste, which cures at a low temperature and is much more expensive”, he added.
