Touchpad

Shin-Etsu Touchpad is a PET-film or PC-film with printed patterning of silver or carbon providing capacitive touch sensor elements. Printed wiring on the film is connecting the touch sensor elements to the driving electronics. The connection to the driver electronics board is generally realized by a tail with a ZIF-connection.
The design of dedicated sensing patterns and wiring is up to the application and developed by a triangle cooperation between customer, the driver circuit supplier and Shin-Etsu Polymer.
