What is rigid flex PCB?

The birth and development of FPC and PCB gave birth to a new product of rigid flex printed circuit boards. Therefore, the rigid flex printed circuit boards is a flexible circuit board and a rigid circuit board. After the laminating and other processes are performed, the circuit board with the characteristics of the FPC and the characteristics of the PCB is formed in accordance with the relevant process requirements.

Rigid flex printed circuit boards production process editing

Because the rigid flex printed circuit boards is a combination of FPC and PCB, the production of rigid flex printed circuit boards should have both FPC production equipment and PCB production equipment. First of all, the electronic engineer draws the circuit and shape of the rigid flex printed circuit boards according to the requirements, and then sends it to the factory that can produce the rigid flex printed circuit boards. After the CAM engineers process and plan the relevant documents, the FPC production line is arranged. The FPC and PCB production lines are required to produce PCBs. After the two soft boards and hardboards come out, the FPC and the PCB are pressed together by a press machine according to the planning requirements of the electronic engineers. After a series of details, the final system is adopted. Become a rigid flex printed circuit boards. A very important link should be that the hard and soft board is difficult and there are many details. Before the shipment, it is generally necessary to conduct a full inspection because its value is relatively high, so as to avoid the loss of related interests caused by the supply and demand sides.

Rigid flex PCB Advantages and disadvantages:

Advantages: The rigid flex pcb has both the characteristics of the FPC and the characteristics of the PCB. Therefore, it can be used in some products with special requirements. It has both a certain flexible area and a certain rigid area. It saves the internal space of the product. , to reduce the volume of finished products and improve product performance is of great help.

Disadvantages: The rigid flex pcb has many production processes, and it is difficult to produce, the yield rate is low, and the materials and manpower are relatively high. Therefore, the price is relatively expensive, and the production cycle is relatively short.

Field of application

The characteristics of the rigid flex pcb determine its application area to cover all the application fields of the FPC in the PCB, such as:

New use

Components such as a suspension circuit (HD) of a hard disk drive and an xe package board.

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.
