Conductive ink for digital printing: low-Ohms and ink-jettable

April 06, 2016 // By Graham Prophet
DuPont Advanced Materials (DuPont) jhas introduced an electronic ink for inkjet printing that offers the high conductivity and strong adhesion required for rapid digital design, prototyping and full-scale manufacturing. The technology will enable digital printing for electronic components and circuits in applications where extremely fine lines are required, such as OLED panels, solar cells, printed antennae and touch panels.

PE410 enables rapid prototyping and a smooth transition from “lab to fab” with the versatility to scale up to industrial high-volume inkjet print heads and machines. This allows circuit designers to immediately test a new design, quickly make necessary edits, and, due to reduced silver laydown, save on material costs. The technology also can be adapted to non-planar printing, enabling a series of new and emerging applications.


“Based on industry benchmarks, we find DuPont’s new conductive inkjet ink to provide the best combination of important properties available among competitive products,” said Jeroen van den Brand, program director, Holst Centre. “When considering the low sintering temperature, conductivity, adhesion, print head stability, fine line capability and substrate compatibility, DuPont’s solution is the leader.”
