Anti-Static ESD/EMI Metal Dome Membrane Keypad Craft Technology

Common materil used in ESD membrane switch :

There are a number of materials you can use to shield your electronic components from ESD.

Polyester

Polyester is a very common and cost-effective option. It is a very thin layer right behind the graphic overlay. Once the silver screen-printed grid pattern comes into contact with ESD, it guides the discharge to the chassis ground.

Aluminum Single Side Coated Foil

A thin aluminum layer, around 3-5 ml, can also be used to transfer the discharge away from the electrical components. The conductive side lays right side up and guides the ESD through a ground chassis point.

Conductive Copper Mesh Fabric

Conductive copper mesh fabric is a very high quality option only used in special applications due to its more expensive price tag. It is frequently used in communication and military units. A single layer of copper mesh fabric will also protect components from electromagnetic interference (EMI) and radio frequency interference (RFI).

LECTROSTATIC DISCHARGE
Electrostatic discharge (ESD) is a short but intense flow of electricity when two electronically charged objects come in contact. In a device with a membrane switch interface, this can happen when the user presses down a button. As you can imagine, ESD can damage sensitive circuitry and other components within the device.

SOLUTIONS FOR SHIELDING INTERFERENCE
Not every membrane switch requires shielding for EMI, RFI, or ESD. In some cases, the graphic overlay provides enough of a buffer to protect the internal components. However, for various reasons – including application, environment, regulations, and more – additional shielding is often warranted.
