The birth and development of FPC and PCB gave birth to the new product of soft and hard board. Therefore, the soft-rigid combination board is a circuit board with FPC characteristics and PCB characteristics formed by combining flexible circuit boards and rigid circuit boards in PCB proofing according to relevant process requirements through pressing and other processes.
In PCB proofing, the rigid-flex board provides the best solution for limited space conditions. This technology offers the possibility to safely connect device components while ensuring polarity and contact stability, and reduces the number of plug and connector components.
Other advantages of rigid-flex boards are dynamic and mechanical stability, the resulting 3-dimensional design freedom, simplified installation, space savings, and maintenance of uniform electrical characteristics.
Rigid-flex boards Rigid-flex boards are expensive, but they are extremely versatile and can be tailored for applications in many industries. There are several situations that make a rigid-flex board the best solution. These include:
1. High shock and high vibration environment. Rigid-flex boards are highly impact-resistant and can survive high-stress environments that would otherwise cause equipment failure.
2. High-precision applications where reliability is more important than cost considerations. If a cable or connector failure would be dangerous, you're better off using a more durable rigid-flex board.
3. High-density applications: Some components lack the surface area required for all necessary connectors and cables. Rigid-flex boards can save space to solve this problem.
4. Applications that require multiple rigid boards. When more than four connection boards are crowded in an assembly, it may be optimal and more cost-effective to replace them with a single rigid-flex board.
