A Novel Primer Coating on Organic Substrate for Reliable InkJet Printed Circuit

摘要

Even though ink jet printed circuit has many advantages over typical subtractive PWB technology such as fewer processes, less waste and labor, it has some problems. A major problem is weak adhesion between circuit and substrate. The other problem with ink jetting conductor is poor line and edge quality. One of the most widely adapted solutions is the substrate surface treatments. The various treatment methods have been used to increase the affinity between substrate and ink. However, the resulting circuit quality was still not good enough to be compatible with conventional circuit. Therefore, printed electronics industry is looking for new method.
