Thermoforming of Printed Conductive Silver on Flexible Substrates

Screen printing is an interesting technique for the high‐volume production of printed conductive electronic devices on flexible substrates. In this study, silver conductive lines have been produced by screen‐printing technique on flexible PEN substrates and optimized in order to provide maximum electrical conduction. The geometry of the obtained conductive samples has been modified by performing thermoforming tests in a mold with complex geometry, replicating a significant section of dashboard coating. The functionality of the shape‐deformed substrates has been assessed.
