Product Description
PET Static Electricity Shielding Design ESD Lexan Mebrane For Computer Keyboard
When it comes to designing computer keyboards with PET (Polyethylene Terephthalate) membranes to protect against static electricity, there are several options available. Here is a summary of the information found in the search results:
-
Electrostatic Discharge (ESD) Shielding for Membrane Switches
- Electrostatic Discharge (ESD) occurs when a body comes into contact with different materials and is charged with negative electrons.
- ESD can cause damage to sensitive electronic components inside membrane switches.
- ESD shielding is essential to prevent the discharge from reaching the circuitry and components.
- Two effective options for ESD shielding are:
a. Screen-printed grid pattern of conductive silver ink: This layer can be grounded to a trace on the interface panel and routed to a grounded plane on the motherboard.
b. Full conductive laminates, tapes, and foils: These provide higher dissipative properties but can be more expensive.
-
Materials Used in ESD Shielding
- Polyester: A common and cost-effective option that guides the discharge to the chassis ground.
- Aluminum Single Side Coated Foil: Transfers the discharge away from the electrical components.
- Conductive Copper Mesh Fabric: A high-quality option used in special applications, also protects from electromagnetic interference (EMI) and radio frequency interference (RFI).
- Indium Tin Oxide (ITO): A clear, electrical conductive transparent material used to shield displays from ESD, EMI, and RFI.
