In the field of automotive electronics, with the development of technology and the improvement of performance requirements, traditional PCB design has been unable to meet the needs of increasingly complex electronic systems. As a new type of PCB solution, the Rigid-flex pcb has brought revolutionary changes to the field of automotive electronics.
I、Problems and challenges
Space optimization: The interior space of the car is compact, and the combination of soft and hard plates is cleverly designed to achieve a high-density layout of the circuit while maintaining the mechanical strength and reliability of the electrical connection.
Durability and vibration resistance: The car will experience various vibrations and shocks while driving, and the design of the Rigid-flex board makes it able to adapt to these conditions to ensure the stable operation of the circuit.
Heat dissipation performance: Compared with traditional PCB, Rigid-flex pcb has better heat dissipation performance and can maintain stable work in high temperature environment.
II、Advantage analysis
Compact package: The design of the hard-soft board allows the board to bend and fold, allowing the package to fit into a smaller space and achieve a high degree of circuit integration.
Improved reliability: Reduces the need for signals to pass through connectors, cables, or welding points, reducing the risk of failure and improving overall system reliability.
Enhanced durability: Flexible parts can withstand multiple bends without loss of performance and are suitable for use in harsh environments.
Cost effective: Although the production difficulty is increased, the additional circuit connections are reduced, reducing the overall cost.
High vibration environment: In high vibration or shock environment, the soft and hard board can maintain the stability and integrity of the circuit connection
III、Specific application
Safety system: In the airbag, brake system, body stability system, the soft and hard board provides a stable circuit connection to ensure the normal operation of the system.
Sensor application: Used to monitor vehicle status, such as temperature, pressure, speed, etc., and transmit sensor data to the electronic control unit for processing.
New energy vehicles: In key components such as battery management system and motor control system, the combination of soft and hard board improves the integration and reliability of the system.
Lidar: As a key component of autonomous driving technology, the combination of soft and hard board improves the impact and vibration resistance of the product and reduces the failure rate of the product.
