Low-temperature sintering of Cu@Ag microparticles in air for recyclable printed electronics
David van Impelen, Lola González‐García, Tobias Kraus
Abstract
An optimal temperature for printed conductors based on silver-coated copper microparticles is 160–250 °C, leading to silver sinter necks that enhance the conductivity. Treatments are done in air and the particles can be recycled from the prints.
