The use of high energy Pulsed Light is presented as a means of sintering printed nano- particle inks to form conductive traces on flexible substrates. These novel metal nanoparticle based inks are ideally suited for photonic sintering due to changes of their basic physical properties based on their size. A phenomenon referred to as melting point depression is related to the change in the surface to volume ratio of the particle allows sintering to take place at temperatures significantly lower than that of the bulk material. Another relevant physical change is the interaction of nanoparticles with light. As these particles have sizes that are smaller than the wavelength of light, plasmon effects can occur which allows increased efficiency in photonic energy absorption as heat.
