What is rigid-flexible PCB circuit boards:

Rigid flex PCB board, that is, flexible circuit boards and rigid circuit boards, through the pressure and other processes, according to the relevant process requirements together to form a FPC characteristics and PCB characteristics of the circuit board. In the past, two hard boards were connected by a flexible board and a connector. In order to improve the connection reliability between the hard board and the flexible board, the flexible board can be manufactured directly between the two hard boards in the printed circuit board (PCB) factory, thereby eliminating the follow-up process. Whether the hard board manufacturer or Soft board manufacturers, is now available for the combination of soft and hard board. In the end product for the thin and light under the requirements for the soft board and soft and hard combination of the scope of application will be broad.

High-end smart phone is still functional rigid-flex combination of the main driving force for the development of the market. Due to more functional requirements, such as word processing powerful, send and receive e-mail, digital camera pixels to enhance the mobile phone hard and soft board to increase the application of static and dynamic can be combined with soft and hard board design, the future with digital TV, Micro-projector, map function to strengthen the mobile phone functions, soft and hard board is bound to the whole machine, modular applications.

Single-sided flex PCB circuits

Single-sided flexible circuits have a single conductor layer made of either a metal or conductive (metal filled) polymer on a flexible dielectric film. Component termination features are accessible only from one side. Holes may be formed in the base film to allow component leads to pass through for interconnection, normally by soldering. Single sided flex circuits can be fabricated with or without such protective coatings as cover layers or cover coats, however the use of a protective coating over circuits is the most common practice. The development of surface mounted devices on sputtered conductive films has enabled the production of transparent LED Films, which is used in LED Glass but also in flexible automotive lighting composites

Double-sided flex pcb circuits

Double-sided flex circuits are flex circuits having two conductor layers. These flex circuits can be fabricated with or without plated through holes, though the plated through hole variation is much more common. When constructed without plated through holes and connection features are accessed from one side only, the circuit is defined as a "Type V (5)" according to military specifications. It is not a common practice but it is an option. Because of the plated through hole, terminations for electronic components are provided for on both sides of the circuit, thus allowing components to be placed on either side. Depending on design requirements, double-sided flex circuits can be fabricated with protective coverlayers on one, both or neither side of the completed circuit but are most commonly produced with the protective layer on both sides. One major advantage of this type of substrate is that it allows crossover connections to be made very easy. Many single sided circuits are built on a double sided substrate just because they have one of two crossover connections. An example of this use is the circuit connecting a mousepad to the motherboard of a laptop. All connections on that circuit are located on only one side of the substrate, except a very small crossover connection which uses the second side of the substrate

Multilayer flex pcb circuits

Flex circuits having three or more layers of conductors are known as multilayer flex circuits. Commonly the layers are interconnected by means of plated through holes, though this is not a requirement of the definition for it is possible to provide openings to access lower circuit level features. The layers of the multilayer flex circuit may or may not be continuously laminated together throughout the construction with the obvious exception of the areas occupied by plated through-holes. The practice of discontinuous lamination is common in cases where maximum flexibility is required. This is accomplished by leaving unbonded the areas where flexing or bending is to occur.

Rigid-flex pcb circuits

Rigid-flex circuits are a hybrid construction flex circuit consisting of rigid and flexible substrates which are laminated together into a single structure. Rigid-flex circuits should not be confused with rigidized flex constructions, which are simply flex circuits to which a stiffener is attached to support the weight of the electronic components locally. A rigidized or stiffened flex circuit can have one or more conductor layers. Thus while the two terms may sound similar, they represent products that are quite different.

The layers of a rigid flex are also normally electrically interconnected by means of plated through holes. Over the years, rigid-flex circuits have enjoyed tremendous popularity among military product designer, however the technology has found increased use in commercial products. While often considered a specialty product for low volume applications because of the challenges, an impressive effort to use the technology was made by Compaq computer in the production of boards for a laptop computer in the 1990s. While the computer's main rigid-flex PCBA did not flex during use, subsequent designs by Compaq utilized rigid-flex circuits for the hinged display cable, passing 10s of 1000s of flexures during testing. By 2013, the use of rigid-flex circuits in consumer laptop computers is now common.

Rigid-flex boards are normally multilayer structures; however, two metal layer constructions are sometimes used.

Rigid-flex PCB introduction:

A rigid-flex PCB (printed circuit board) is a type of circuit board that combines both rigid and flexible materials in its construction. It offers the advantages of both rigid and flexible PCBs, making it suitable for applications where space constraints, complex geometries, and reliable interconnections are important.

In a rigid-flex PCB, the board consists of multiple layers of rigid materials, typically FR4, and flexible materials, such as polyimide. The rigid portions provide structural support and accommodate components, while the flexible areas allow the board to bend or fold as needed.

Rigid-flex PCBs are commonly used in electronic devices that require a compact form factor, such as smartphones, tablets, wearables, and aerospace applications. They offer several benefits over traditional rigid PCBs, including:

Size reduction: Rigid-flex PCBs can eliminate the need for connectors and cables, enabling a significant reduction in space requirements.

Increased reliability: Rigid-flex PCBs have fewer interconnects and solder joints compared to traditional PCBs, reducing the potential points of failure. They also offer better resistance to vibration and thermal stress.

Improved signal integrity: The combination of rigid and flexible materials allows for optimized signal routing, reducing signal loss, and improving overall signal integrity.

Enhanced design flexibility: Rigid-flex PCBs can be designed to fit complex and irregular shapes, conforming to the available space in a device. This flexibility enables innovative product designs.
