Micro-printed Silvers

Sheldahl® uses high-speed, roll-to-roll processes to apply micro-printed silver inks, which are ideal for mutual-capacitance switch nodes with backlighting graphics.

Typical applications for Sheldahl’s micro-printed silvers include transparent capacitive switches, projected capacitive touch sensors, flexible displays, and flexible photovoltaic solar cells.

Base Films & Adhesives:

  • Clear PET (75µm, 125µm thick)
  • Optically Clear OCA/PSA (3M 467, 3M 8172)


  • High resolution printing of a non-transparent silver ink in a Hexagon pattern created the switch nodes while 75-90% of the surface remains uncovered
  • Printed PTF silver defines the traces connecting the switch nodes through the connector tail
  • Carbon PTF ink can be printed in the connection area for durability and reliability
  • The body of the switch circuit can be covered with either PET Coverfilm or a clear printed mask for protection.
