What is a single-sided Flex Circuit Pcb ?
Single-sided flexible PCB (Single-sided flexible PCB) is an electronic circuit board made of flexible substrate materials. It only has wires and circuit components on one side, while the other side is a bare flexible substrate. This design makes the single-sided flexible board very thin, light, flexible, and has high bending performance. They can be zigzag installed on the curved surface of the equipment or in the limited space, so as to realize the connection and function of the circuit. The advantages of using single-sided flexible boards over conventional rigid circuit boards include small size, light weight, good flexibility, and strong vibration and impact resistance.
The following will introduce in detail the practical case of Capel Flex Printed Circuit Board in Volkswagen sensors

This includes the type and quantity of sensors, the size and shape requirements of the flexible board, and the circuit connection requirements with other components,etc.
Design and development: Based on the results of demand analysis. Capel’s technical engineering R&D team began to design and develop single-sided flexible boards. Designers use software tools and CAD technology to create the circuit diagram and layout design of the flexible circuit board, taking into account the integration with the Volkswagen sensor system.
Material selection: During the design process, the Capel team selected materials suitable for the automotive environment, such as polyimide These materials have excellent properties such as high temperature tolerance, vibration resistance, chemical resistance and electrical insulation to meet the requirements of automotive sensor systems. Manufacturing and Production: When the FPC design was completed and verified, the Capel team started the manufacturing and production process. Following the strict process flow, combined with ultra-high process capability and advanced imported fully automated equipment, the circuit diagram is transformed into actual flexible circuit board products, including control circuit, welding, and testing and other processes.
Integration and testing: The manufacturing process of single-sided flexible boards requires rigorous testing and verification to ensure the performance and reliability of the sensor. The testing and validation phase typically includes electrical testing, temperature and environmental stability testing, and high-speed data transmission testing, among others Through these tests, the function and reliability of single-sided flexible boards in automotive applications can be guaranteed.
The completed single-sided flexible circuit board is transferred to Capel’s electronic component placement and testing factory for integration and testing with the sensor system. Connect flex boards to sensors and other electronic components and ensure proper operation and accurate data in real-world use.
System optimization and iteration: In the process of integration and testing, some problems or improvement points are found. The Capel engineering technology R&D team and the Volkswagen team have been maintaining technical discussions and close cooperation, step by step system optimization and iteration, and finally ensured that the performance and reliability of the single-sided flexible circuit board reached the best state.
Driving test and verification: Finally, Volkswagen conducted a driving test and verification to ensure that the single-sided flexible circuit board operates normally under actual road conditions, and the performance and data accuracy of the sensor system meet the expected requirements.
Capel’s single-sided flexible circuit board technology provides technical innovation and reliability for Volkswagen’s sensors
Provide thin and flexible solutions: Single-sided flexible circuit board technology provides thin and flexible solutions for sensors, which can adapt to the space constraints of different parts of Volkswagen. Compared with traditional rigid circuit boards, single-sided flexible boards can be more flexibly arranged and installed in every corner of the car. providing more optional locations and installation methods. Improved Durability and Vibration Resistance: Single-sided flex circuit technology enhances sensor durability and vibration resistance. The softness and elasticity of the soft board can reduce the impact of external impact and vibration on the circuit board, thereby improving the stability and reliability of the sensor. This is very important for different road conditions and vibration environments during driving.
Improve response speed: The flexible nature of single-sided flexible boards enables them to adapt to the complex shapes of automotive parts and structures, providing better mechanical adaptability. This means that the single-sided flexible board can arrange sensors in the narrow space of the vehicle, improving the reliability and response speed of the system.
Improve reliability and performance: Single-sided flexible boards usually use polyimide (PI) as the base material because of its excellent heat resistance, chemical stability and mechanical strength. PI materials remain stable at high temperatures and harsh environments, making them ideal for automotive applications. Integrated circuit (IC) embedding: The single-sided flexible board can directly embed IC chips in it, making the sensor system more compact and integrated. By integrating ICs on a single-sided flexible board, the connection lines between circuits can be reduced, thereby improving system reliability and performance.
Improved data accuracy: Sensors using single-sided flex sheets in vehicle safety systems can detect and measure important parameters such as crashes, braking, and stability to ensure vehicles remain safe in various situations. And because the single-sided flexible board has the characteristics of flexibility, lightness and plasticity, it can better adapt to complex vehicle structures, maintain stability under harsh conditions, provide good signal transmission, and provide accurate sensing data.
Detection accuracy: A single-sided flexible board sensor is used to monitor the surrounding environment of the vehicle to provide better driving assistance functions. The flexible characteristics of the single-sided flexible board enable the sensor to better adapt to the vehicle surface and provide more accurate and reliable environmental perception data.
Reduce the risk of connecting electronic components: Single-sided flexible board technology reduces the risk of connecting electronic components by reducing connection points and connecting lines. The fewer connection points and wires between the electronic components inside the sensor, the lower the complexity, vulnerability and failure rate of the system. The application of single-sided flexible board technology can reduce the number of connection points, thereby improving the reliability of the sensor.
Provide better dustproof and waterproof performance: single-sided flexible board technology provides better dustproof and waterproof performance, protecting the sensor from the external environment such as dust, moisture, and water. This is very important for reliable operation in the harsh external environment of the car, such as rain, mud, or harsh weather.
Reduce energy consumption: Single-sided flexible circuit board technology adopts efficient circuit layout and optimized circuit design, which can reduce the energy consumption of sensors, better integrate with automotive structures and parts, and reduce the material and space requirements of circuit boards. This not only reduces the weight of the car and improves fuel efficiency, but also helps reduce waste in the production process, contributing to energy saving and environmental protection in the automotive industry.
Compared with traditional rigid circuit boards, the design of single-sided flexible boards is more compact, and the distance between circuits and the length of wires are shorter, thereby reducing the loss of energy transmission and improving energy utilization efficiency.
Improve system integration capabilities: The flexible design and high-density connection of single-sided flexible boards enable them to be effectively integrated into sensor systems, and its technology can realize the integration of a variety of different sensors. By integrating multiple sensors into a flexible circuit board, the connection points in the system can be reduced, the size of the hardware can be reduced, the efficiency of information exchange can be improved, the failure rate of the overall system can be reduced, and collaborative work and data exchange can be realized.
