Step 4: Connect Active Areas to Leads

The last step involves connecting the active areas to the copper tape attached in the previous step.

  • Using the remaining carbon grease, draw a line of carbon grease from one active area to a strip of copper tape.
  • Connect the active area to the strip which is connected to the same side of the membrane.
  • The carbon grease does not need to fully cover the copper tape, but a generous contact area will guarantee good conductivity.
  • Flip the actuator over and paint a line from the active area to the copper strip attached on this side.
