| Abstract Scope |
Conductivity in polymer-based conductive particle charged inks is based on the juxtaposition of typically metallic particles to form a continuous physical path for electrons to flow according to the electrical field applied. When pad printing such inks using a low temperature process on various kinds of substrates, a sintering process optimizes and stabilizes its electrical conductivity. Due to its short cycle time and its medium costs, near infrared light pulse exposures, in the second range, offer an alternate approach for drying and sintering inks. This work presents various contexts of pad printed electronic circuits and sensors. It presents experimental data and discusses the use of a near infrared light sintering process for conductive test traces. It focuses on pad printing of an acrylate-based ink with 1 micron silver particles on a polycarbonate substrate, a material used for medical devices. It compares the results with other classical sintering methods. |
