Abstract

Disclosed is a method for protecting operator panel circuitry from Electrostatic Discharge (ESD) by using an overlay that is silk screened with conductive ink and conductive adhesive, when installed the conductive adhesive makes contact to a metal contact surface, which is frame ground.

Operator Panel Conductive Overlay using Conductive Ink and Adhesive

      Disclosed is a method for protecting operator panel circuitry
from Electrostatic Discharge (ESD) by using an overlay that is silk
screened with conductive ink and conductive adhesive, when installed
the conductive adhesive makes contact to a metal contact surface,
which is frame ground.

      The operator panel displays, switches, and circuitry are
covered with an acrylic overlay which has the color, identification
lettering, and instructions silk screened on the back side.  The
overlay is attached to the bezel with an adhesive.  The ink and
adhesive are made conductive and a path to frame ground is provided
through a spring contact.
