EMC shielding of foil keyboards

You can chose from two procedures for the EMC shielding of foil keyboards:

Process 1

A polyester foil covered by copper or aluminum gets laminated into the foil keyboard under the front foil. The contacting with the housing wall or carrier plate occurs at least over one integrated terminal lug, which gets conductively tied to the mechanics.

Process 2

A polyester foil, covered completely by means of screen painting or covered with a grid structure by conductive silver technology gets integrated into the keyboard. In this case contacting can occur over the foil cable and the plug connectors directly to the circuit boards or mechanics.
