Product Description

Polyimide FR4 Density PCB Assembly 28-Layer Rigid Flex Circuit Board with SMD Components

Product Description:

The Rigid Flex PCB, with a sophisticated construction of a 4 Layer board, represents a pinnacle of modern circuit board technology that blends the best of both worlds in terms of flexibility and rigidity. This innovative product stands out as a Flexible Stiff Circuit Board, offering unparalleled adaptability and robustness for a vast array of electronic applications. With meticulous attention to detail, this board is engineered to meet the highest standards of quality and performance.

One of the hallmark treatments of the Rigid Flex PCB is its variety of surface finishes which includes ENIG (Electroless Nickel Immersion Gold), OSP (Organic Solderability Preservatives), Immersion Gold, Tin, and Silver. Each of these treatments is designed to enhance the board's longevity, reliability, and solderability, ensuring that your product performs consistently over time. The choice of finish allows for flexibility in the application, with ENIG being particularly useful for its excellent surface planarity, OSP for its eco-friendly nature, Immersion Gold for its superior conductivity, Tin for its cost-efficiency, and Silver for its excellent thermal and electrical properties.

The precise dimensions of the Rigid Flex PCB are 41.55*131mm, meticulously crafted to fit a wide range of devices while maintaining a compact form factor. This size is particularly suitable for sophisticated electronic devices where space is at a premium, and efficient use of every millimeter is crucial. Whether it's for consumer electronics, medical devices, or aerospace technology, the carefully calculated dimensions ensure a perfect fit and optimal performance.

When it comes to components, the Rigid Flex PCB is designed to support a variety of electronic components including SMD (Surface Mount Devices), BGA (Ball Grid Array), DIP (Dual In-line Package), and more. This versatility allows for a diverse range of components to be mounted on the circuit board, making it an ideal choice for complex electronic assemblies. The board's design also takes into account the evolving nature of electronic components, ensuring compatibility with both current and future technologies.

Accuracy is of the utmost importance in PCB manufacturing, and our Rigid Flex PCB boasts a remarkable Hole Position Deviation of ±0.05mm. This level of precision is critical when dealing with advanced electronic components, particularly those with fine pitch such as BGA. Such precision ensures that each component is perfectly aligned with the board's layout, leading to a reliable electrical connection and reducing the risk of manufacturing defects.

The Rigid Flex PCB is not just a Foldable Rigid Circuit Board; it's a testament to the advancements in PCB technology. Its ability to bend and fold without compromising the integrity of the circuit makes it an ideal solution for dynamic applications where movement and flexibility are necessary. It brings forth a solution that is both mechanically stable and adaptable, capable of sustaining repeated flexing without failure. This characteristic opens up new possibilities for innovative product designs that were previously constrained by the rigidity of traditional PCBs.

In essence, the Rigid Flex PCB is a versatile, high-quality circuit board solution that finds its place in numerous high-tech industries. With its combination of a Flexible Stiff Circuit Board design, advanced component compatibility, precise hole alignment, and a variety of surface treatments, this product is truly at the forefront of PCB technology. It is designed for those who seek excellence in their electronic products, providing a foundation that enables complex functionalities in a reliable and efficient manner.
