Abstract
Printed intelligence is a promising new technology to
produce low-cost electronics. Non-conductive circuits can
be printed using nanoscale metal particle inks. Due to
the nanoscale size of the particles, the typical
sintering temperatures of 100-300 °C are only a fraction
of the macroscopic melting point of the corresponding
materials, thus allowing the use of paper or plastic
substrates. Sintering of printed nanoparticle structures
using laser treatment has been investigated at VTT.
Laser sintering can be utilized in manufacturing of
printed conductor structures such as antennas, circuits
and sensors. A drop-on demand printer was used to print
patterns with metallo-organic silver nanoparticles on a
flexible polyimide substrate. Laser sintering was made
with a 940 nm CW fiber coupled diode laser. Process was
optimized using different laser power levels, line
separation and repetition rounds. Conductivity of laser
sintered samples was compared to conductivity of samples
sintered in convection
oven.
