For cars, both fuel vehicles and electric vehicles need to use Flexible printed circuit (FPCB). In an automotive, up to 100 Flexible printed circuits may be used. Many sensors, cameras, radars and other electronic devices in modern cars need to be connected by Flexible printed circuit, which can withstand the challenges of the external environment of the car, such as temperature changes, humidity, vibration, etc., and ensure the stable operation of electronic equipment. In addition, Flexible printed circuit (FPCB) can also be used in the lighting system of the car, such as headlights, instrument lights, etc. Because it has excellent conductivity and flexibility, and it can meet the complex line layout and curved surface design requirements of headlights, and improve the design freedom and reliability of headlights.
Development trend of Flex PCB technology in automotive
Flex PCB technology was first introduced in 1950. Today, it is not a new technology, but its application in the automotive field is gradually becoming popular just like other traditional technologies crossing over to the automotive field. It will be very smooth to use Flex PCB technology in automobiles. The wiring harness system of traditional automobiles is complex and messy, and multiple interfaces bring complex and high costs to the vehicle electronic system. In the era of smart cars, the algorithm capabilities of vehicle computers have far exceeded the current connection technology, so the change of carriers is only a matter of time.
Core application of Flexible printed circuit in automotive lights
In automotive lights, Flex plus FPC brings more possibilities to lighting design, improves functionality and performance, and makes automotive lights more intelligent and personalized. The application of Flex PCBs in automotive lights has the advantages of flexibility, bendability, and easy wiring, which can meet the requirements of flexibility and reliability in automotive light design. At the same time, through the Flex PCBs application, the integration and design freedom of automotive lights can be improved, and more diverse lighting effects and functions can be achieved. Flexible printed circuits are mainly used to connect and drive various electronic components in lamps to realize the functions of lighting on and off, dimming, and flashing. Flexible printed circuits (FPCB) can adapt to complex design requirements and ensure stable operation. They have high space utilization, strong reliability, strong anti-interference ability, high temperature resistance.
Lamp bead connection:
Flexible printed circuit (FPCB) can connect LED lamp beads with driver circuit boards to realize power supply and control signal transmission of LED lamp beads. The flexible characteristics of Flexible printed circuit allow it to adapt to complex lamp shapes and simplify the layout of connection lines.
Light strip connection:
The commonly used light strips in automotive lights (such as daytime running lights, brake lights, turn signals, etc.) can also be connected to the driver circuit board through Flexible printed circuit to realize power supply and control of the light strips. The flexibility and bendability of Flexible printed circuit enable it to adapt to the curves or curved shapes of the light strips.
Light control module connection:
The control modules in automotive lights usually include light switches, dimmers, flashing controllers, etc. FPCBs can be used to connect these modules with lamps to realize functions such as control, adjustment and flashing of lights.
Signal transmission:
Flexible printed circuit can also be used to transmit vehicle signals, such as brake signals, turn signals, etc., and transmit these signals to the driver circuit board of the automotive lights to realize the corresponding response of the automotive lights.
