Photon sintering is a new type of printed conductive paste rapid sintering technology.

ZHONGWU Roll-to-Roll Photon Sintering System DESCRIPTION

It is to use metal particles to selectively absorb broad-spectrum ultraviolet light, so that metal particles absorb light energy to achieve sintering. 

Since the light energy is only absorbed by the metal particles, the substrate material does not have a significant temperature rise while achieving the sintering circuit, and thus is particularly suitable for various plastic films and paper substrates. It can be used to sinter copper as well as silver inks, and is designed to work with inks from various manufacturers.
