High density R2R screen printed silver interconnections for hybrid system integration

In this case study, we investigated the minimum line width and spacing for roll-to-roll (R2R) screen printed silver interconnections on polyethylene terephthalate (PET). This initial pilot investigation involved rotary screen printing 16 high density I/0 patterns while alternating pitch (150, 175, 200, and 250 μm) and nominal screen linewidth (50, 75, 100, 150 μm).
