The project focuses on studying inkjet printhead compatible Ni nano ink compositions and sintering conditions for ensuring conductivity after printing. Elephantech will continue to expand the variety of metal ink types the company handles to promote further the use and application of inkjet technologies in an ever-growing number of fields, including electronic component manufacturing processes.

[Key point of the announcement: the roles of the three parties]
Elephantech, ORIST and SSTechno are collaborating on a project to make electrode layers even
