Autotex Polyester Customizable ESD Membrane Film Keyboard With ITO
Film Design
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).
Indium Tin Oxide (ITO)
Indium Tin Oxide (ITO) is a clear, electrical conductive
transparent, plastic polyester material that is used when a display
needs to be shielded from electrostatic discharge. It is difficult
to produce and can be more costly, but will fully protect the
display area from ESD, EMI, and RFI.
ESD shielding is particularly important in applications where
membrane switches are exposed to environmental factors that can
generate static electricity, such as:
- Industrial machinery and equipment
- Medical devices
- Automotive electronics
- Consumer electronics with touch-sensitive interfaces
By incorporating an ESD shielding membrane into the design,
manufacturers can ensure that their membrane switch products are
more resilient and less susceptible to damage from electrostatic
discharge, improving their overall reliability and performance.
