Presentation Title:

Controlling the Microstructure of Screen Printed Conductors to Improve Their Conductivity

Time: TBD

Presentation Abstract:

George Xiao, Ye Tao and Zhiyi Zhang

Screen printing is the main choice for the manufacturing of membrane switches, printed RFID antennas, printed sensors and etc. Conductivity is one of the main specs required for the printed conductors which formed the printed devices. Higher conductivity usually means better device performance and/or the saving of inks. It has been found that the conductivity of the screen printed conductors is directly related to their microstructures. The screen printed silver conductors with proper controlled microstructures could offer 3 times higher conductivity than their counterparts processed using the conditions recommended by the ink suppliers (DuPont or Henkel). In this presentation, the fundamentals for the microstructure variations of printed conductors are elucidated; the correlation between the conductivity and the microstructure is reported; approaches used for the microstructure control are presented; the application of microstructure control for the fabrication of RFID antennas is also reported.
