Printing technology and process

As a novel means of manufacturing electronic products, the inks used in printed electronics will eventually work as conductors, semiconductors, resistors, dielectrics, and insulating layer. The requirements in accuracy and resolution for printing electronics are also much higher compared to the traditional printing industries. As a result, the research in printing technology and process is necessary.

The methods such as inkjet, gravure, or screen printing fabricate patterns with varied characteristics, and need inks with different physical properties for printing. The research in the matching ability between printable electronics materials and printing methods can guide the applications of different printing methods in printed device fabrication, and put forward novel printing technology. These researches are also helpful in selecting the appropriate method in the printed electronics manufacturing, improving the pattern quality, production speed and reduce the difficulty of ink production.

The theory of physics, as well as experience in the electronics manufacturing industry show that properties of electrical materials such as crystal form, purity, doping uniformity, surface morphology, interface contacts will greatly affect the performance of the device. During the manufacturing process, a variety of physical movements and chemical reactions of the printed ink will bring the printed functional layers complex structures, and play key roles in the electrical properties of the final products. Choosing the right inkúČstudying if the ink matching the printing method and substrate, and optimizing printing parameters can control the movements and reactions mentioned before, then improve the electrical property of the printed pattern.

Pre-printing processes and Post-printing processes also have pivotal positions in printed electronics. For example, substrate treatments in pre-printing processes can significantly improve the quality of printed pattern. While the post-printing operation including sintering and annealing can get much better macro- and micro-structure of the printed film, and make the electrical properties meet the design targets.
