Rigid Flex
Rigid flex circuits combine the advantages of rigid boards and flexible circuits into one circuit.
The rigid outer layer is connected to the inner flexible layer using copper plated vias. Rigid flex circuits offer higher component density and better quality control. The design is rigid in areas where additional support for the SMT components is required and flexible in areas where bending and bending is required to fit into tight spaces.
With the continuous development of electronic technology, the demand for multi layer flexible circuit boards is also growing. It may continue to develop towards higher performance, smaller size, and more flexibility in the future.

There are many high level benefits to Rigid Flex circuits including:
Connection Reliability
Connecting rigid layers with flexible cables is the foundation for a combination of rigid flex circuits. Rigid flex constructions eliminate the need for board-to-board connectors or wiring harnesses to link rigid boards together.Connecting rigid layers with flexible cables is the foundation for a combination of rigid flex circuits. Rigid flex constructions eliminate the need for board-to-board connectors or wiring harnesses to link rigid boards together.
Reduce parts count
Compared with traditional rigid boards, Rigid flex circuits require fewer parts and interconnections by eliminating wire harnesses and board-to-board connectors.
Flexible design options
At Flexible Circuit Technologies, we pride ourselves on guiding our customers through their most complex design challenges to deliver the most reliable and cost-effective designs. By utilizing rigid and flexible substrates, rigid-flex circuits can be designed to accommodate highly complex and unimaginable configurations. Rigid flex circuit design can include any of the following:
- Highly complex configurations
- Controlled Impedance
- High layer count
- Reduced interconnections
High density applications
By eliminating interconnection hardware, the combination of rigidity and softness can free up space, thereby achieving higher connection density. Generally, the rigid area of a rigid flexible circuit is used for high-density SMT device groups. The flexible region connecting the rigid region allows the circuit to form a 3 dimensional shape with multiple interconnected rigid regions on different planes.
Package size and weight reduction
Due to the ultra thin characteristics of flexible circuit materials and the ability to create very narrow circuit traces, higher connection density can be achieved while significantly reducing the overall system weight. The inherent low quality of rigid flex materials makes this interconnection system ideal for high shock and vibration applications.

Rigid Flex Applications
Static application
An application that only requires a flexible circuit to be bent during installation to adapt to its application (also known as curved installation).
Dynamic bending application
An application where the flexible area is dynamically bent during normal operation. This range can range from a few hundred cycles to more than 1 million cycles.
Advances in rigid circuit board technology have broadened the scope of the application of electronic products, from computers, communications, and consumer electronics to automotive, medical, and military electronics. The growing demand for more powerful and smaller products has driven the demand for multiple layers to accommodate denser, finer line widths and spacing, as well as smaller hole sizes.

Rigid Flex Materials
Conductor
Copper is the most widely used conductor used to build flexible and rigid flex conductors. Copper is available in a variety of thicknesses to meet customer requirements for current carrying capacity and voltage drop. Copper thickness is usually specified in ounces/square foot. The most common thickness is 1/3 ounce (.0005”/12um), ½ ounce (.0007”/15um), 1 ounce (.0014”/35um and 2 oz (.0028”/70um) Conductor options include：

Flexible Printed Circuits FPC Advantages
FPC is a printed circuit made of flexible insulating substrate, with many advantages that rigid printed circuit boards do not have:
- can be free to bend, coil, and fold, according to the requirements of the spatial layout of any arrangement, and in three-dimensional space, arbitrary movement, and expansion, to achieve the integration of component assembly and wire connection;
- The use of FPC can greatly reduce the volume and weight of electronic products, applicable electronic products to high-density, miniaturization, and high reliability in the direction of development needs. Therefore, FPC in aerospace, military, mobile communications, laptop computers, computer peripherals, PDA, digital cameras, and other fields or products have been widely used;
- FPC also has good heat dissipation and solderability as well as easy to install and connect, has a lower overall cost, and has other advantages.
