Laser Sintering - a sustainable and rapid post-process for high volume production

Diode lasers are by far the most efficient method to introduce thermal energy into NIR absorbing materials. Fortunately, most conductive inks absorb the 940nm of the Hamamatsu cw SPOLD laser, allowing a homogeneous and rapid sintering result comparable to other thermal post-processing technologies. The use of laser line optics favours scalable, yet highly sustainable high volume production, for example in an R2R machine or ITO Touch display manufacturing. Hamamatsu's own developments in terms of lasers and optics make it possible to adapt to customer-specific requirements, materials and processes.
