Using powerful Xenon UV flash lamps
The market for printed circuitry is in a state of upheaval. Inks containing metallic nanoparticles enable printing on flexible, low-cost carrier substances such as paper and various plastic films. The challenge in sintering printed materials lies in maintaining a low heat input in the substrate at the same time. Polytec’s Xenon UV flash lamp systems provide the perfect solution to this problem.
Polytec offers various systems for R&D applications industrial in-line production.
As the European test centre for photonic sintering for the US partner company Xenon Corp., Polytec offers the technical prerequisites for testing photonic sintering.

Industrial Systems
Sintering printed silver materials in the production process
The Sinteron S-5000 enables printed electronics to be processed on flexible substrates such as plastic films, fabrics and paper at a throughput of up to 30 meters per minute.
A maximum of ten lamps each measuring 49 cm in length can be separately controlled using a touch panel, as can the roll speed, footprints and overlaps as well as the pitch of the flash lamps.
A 16″ conveyor belt can be easily removed for integration in roll-to-roll systems.
Sinter materials on wide path substrates with ease
The Sinteron S-5100 is a big step forward for printed electronics. It enables you to sinter printed circuitry on wide path substrates in a roll-to-roll production environment.
