4 Layer Rigid Flex Pcb Assembly Enig Treatment 1-28Layers Profiling Punching 0.5-10Mm Bend Radius

Product Description:

The Rigid Flex PCB, also known as the Flex-Rigid Printed Circuit Board, represents a remarkable fusion of robustness and flexibility, designed to meet the stringent demands of modern electronics. This hybrid circuit board combines the best attributes of rigid printed circuit boards and flexible circuits to offer an unparalleled level of versatility and reliability. With the capability to bend and twist without compromising the integrity of the electrical connections, this Bendable Printed Circuit Board is an ideal solution for dynamic applications where space is at a premium and complex three-dimensional configurations are necessary.

One of the most critical specifications of any PCB is the precision of hole locations, and our Rigid Flex PCB boasts an impressive hole position deviation of ±0.05mm. This level of accuracy ensures that components fit perfectly, and the board operates as intended, even in the most complex assemblies. The precision in manufacturing extends to the overall dimensions of the board, which measures 41.55*131mm, making it suitable for a wide range of applications from medical devices to aerospace instrumentation.

The materials used in the construction of the Rigid Flex PCB are carefully selected to provide the best performance and durability. FR4 is a widely respected composite material known for its excellent flame resistance, electrical insulation properties, and mechanical strength. Polyimide is used for the flexible layers of the board due to its outstanding thermal stability, chemical resistance, and flexibility. Additionally, PET, known for its good balance of mechanical and electrical properties, is also utilized to enhance the board's performance. Together, these materials create a Flex-Rigid Printed Circuit Board that is not only bendable but also durable and capable of operating in challenging environments.

In terms of layering, the Rigid Flex PCB is truly remarkable, supporting configurations of up to 52L (Max Layer). This extraordinary layer count enables the integration of multiple circuits into a single, compact package, which is essential for high-density electronic applications. Whether it's for advanced communication equipment, sophisticated control systems, or cutting-edge medical technology, the ability to accommodate such a high number of layers makes this PCB a go-to choice for designers and engineers.

Surface treatment is another aspect where our Flex-Rigid Printed Circuit Board stands out. Customers can choose from a variety of finishes, including ENIG (Electroless Nickel Immersion Gold), OSP (Organic Solderability Preservatives), Immersion Gold, Immersion Tin, and Immersion Silver. Each of these treatments is applied to ensure the best possible surface for soldering, longevity, and protection against oxidation. ENIG offers excellent surface planarity and a long shelf life, making it ideal for fine-pitch components. OSP is a cost-effective and environmentally friendly choice that provides a flat surface and is suitable for lead-free soldering. Immersion Gold, Tin, and Silver all offer their unique benefits, from excellent conductivity to superior solderability.

In conclusion, the Rigid Flex PCB is a sophisticated, high-performance solution that bridges the gap between traditional rigid PCBs and flexible circuits. Its precision, material quality, high layer count, and versatile surface treatments make it a powerful choice for a multitude of applications. Whether you are looking to push the boundaries of electronic design or seeking a reliable and space-efficient circuit board, this Bendable Printed Circuit Board is engineered to go beyond the expectations of the most demanding projects.
