EMI electromagnetic shielding film-electromagnetic shielding material
Electromagnetic shielding film is also called EMI
protective film, or absorbing material. After the punching process,
it is pressed on the non-adhesive copper clad laminate or cover film
to reduce or eliminate electromagnetic interference on the internal
circuit. This material is widely used in the flexible circuit board
(FPC) industry.
The hot-pressed shielding film can meet the integrity requirements
of high-frequency signal transmission and effectively shield the
interference of electromagnetic waves. The product has the
characteristics of excellent flexibility, extremely low insertion
loss, extremely high shielding effectiveness and stable impedance
control. Specially used in FPC flexible circuit boards and
rigid-flex boards.
Features
Prevent the intrusion of external interference, and prevent
interference from the inside to the outside
Excellent electromagnetic shielding performance (65dB)
Excellent high temperature resistance 300℃
Bending resistance performance (8000-12500 times)
Electromagnetic shielding film meets the requirements of
lightweight, high shielding performance, and wide shielding frequency band
Shield characteristic
Using high shielding performance (low surface resistance value) and film
characteristics (punching processability, flexibility, stretch and toughness),
it is used for space-saving mobile equipment, cable insulation materials that
require curved surface processing, etc. , Electromagnetic wave shielding of
various digital equipment.
Product Applications
Shield the electromagnetic
interference outside the FPC flexible circuit board/flex-hard combined board.
High-signal transmission components
such as touch panels, LCM modules, high-definition cameras, battery components,
and mobile phone antennas.
Used to improve the antenna
sensitivity of mobile phones; used to prevent radiated electromagnetic waves
from HDD.
Used for shielding and sealing; used
for very fine line coaxial cable.
Used for flat cables; used for Card
Skimming countermeasures.
Other applications such as car
navigation systems, digital cameras, HD/DVD, etc.
