Shocking rigid-flex printed circuit boards
In today’s society, more and more PCB designers are facing the pressure of building denser electronic devices. In order to reduce the additional pressure on manufacturing costs and time, engineers and PCB designers are constantly looking for new technology, rigid-flex printed circuit boards. Appears have become the gospel of people. A solution is provided for many product designs.
The rigid-flex printed circuit boards were born, although some aspects of the rigid-flex printed circuit boards may become new on the PCB technology road. But many advantages of rigid-flex printed circuit boards make it a popular PCB design board.
The main material of rigid-flex printed circuit boards is FR-4 (TG170)+polyimide. The number of layers is controlled in 4 layers. The thickness is 1.0mm. The thickness of copper is 35um / 1oz. The surface is ENIG, gold is 0.05-0.1um. Nickel 3-5um treatment, solder green mask.
Advantages of rigid-flex printed circuit boards:
1. Dynamics: Flexible circuits provide unlimited packaging geometric freedom while maintaining the precise density and repeatability of printed circuits.
2. Mechanical stability: The exchange layer of the circuit forms a solid foundation. Rigid panels provide stability while flexible panels provide the flexibility needed for installation in small spaces.
3. Space-saving and capital: The use of the rigid-flex circuit board can greatly reduce the total cost and expenditure of PCB.
4. Security: It provides a secure connection to other components, providing stability and polarity. It also helps reduce the number of connector components in your application. Multi-functional advantages make rigid-flex printed circuit boards more widely used in wearable devices, embedded, consumer electronics, drones, etc.
