Film heater
A wiring pattern formed on the film works as a heater by passing electric current.
Features
It works as a film heater by passing current through wiring patterns created by lamination technology and ultrasound-based fine wiring technology.
Wiring pattern technology
Since wiring patterns with high degree of freedom can be constructed, optimal wiring patterns are applied to parts requiring high light transmittance to achieve anti-fogging and deicing functions.
(No pattern mask or printing plate is required, and wiring can be designed based on CAD data.)
Environmental
Compared with a planar heater that uses etching, etc., it uses a metal wire with a constant wire diameter, so it has features such as less fluctuation in characteristic impedance and less waste liquid and waste material, making it environmentally friendly.
Available conductors
The wire diameter can be selected from 0.05 to 0.12mm, and can be selected according to the purpose.
Copper, Nichrome (NiCr), Kanthal (FeCrAl), Tungsten, etc. are available as the wire.
Applications
Millimeter-wave radars, LiDAR, cameras, lamps, etc.
It is effective for snow-melting and ice-melting functions, prevention of fogging, keeping warm, etc. to parts requiring high light transmittance.
Headlamp
Traffic lights, signs, signboards, and other lamps
