Product Description
Custom Electrostatic Discharge Shielding (ESD) Membrane Switch For Radio Device
As a body comes into contact with different materials, it is charged with negative electrons. When those electrons come into contact with grounded conductive objects such as those found in membrane switches, they create a quick discharge of energy, or electrostatic discharge (ESD). For a fraction of a nanosecond, this discharge can reach up to 15,000 volts (15kV) with a current of up to 30 amperes.
When a user manipulates a membrane switch, the discharge passes from the user to the switch and the sensitive electronic components inside, potentially wreaking havoc on the delicate ecosystem of wires and circuits. Even though a fraction of a nanosecond is a very short amount of time, the levels of ESD are extremely high, and it only takes a small portion of this brief discharge to cause a circuit to malfunction, or other forms of serious damage to electronics. It is critical that membrane switches be designed to prevent the ESD arc from reaching their sensitive circuitry and components.
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.
