Saad Ahmed observes the challenges faced by direct printing of circuits with conventional printing processes
One of the challenges in producing commercial printed electronics products has been the effective sintering of inks on substrates that can be damaged by high temperatures.
Photonic sintering, which uses high-energy light pulses, has solved this challenge in some applications, but many other applications still pose difficulties.
A new “dual pulse” approach to photonic sintering, utilising two pulse profiles operating as a single pulse, may hold the key to addressing these more challenging applications.
