As a connecting device, compared with traditional wiring and rigid boards, the main advantages of flexible circuits include：
- Reduce wiring errors
- Eliminate mechanical connectors
- Unparalleled design flexibility
- Higher circuit density
- More stable operating temperature range
- Stronger signal quality
- Improved reliability and impedance control
- Reduced size and weight
Flexible printed circuits have many benefits, including：
Reduce assembly errors
With precise design and automated production, flexible circuits eliminate human error in handmade wiring harnesses. Except for production-caused errors, the circuit is only routed to those points required by the accurate design plan.
Reduce assembly time and cost
Flexible circuits require less manual labor and reduce production errors during the assembly process. Flexible circuits have the inherent ability to integrate form, assembly, and function. Flexible circuits eliminate the high cost of wiring, winding, and welding wires. Install or replace a complete interconnection system instead of a separate hard PC board. As a result, wiring errors are eliminated and manufacturing costs are reduced. Whether it is small scale production of complex circuits or large scale production of simple circuits, assembly time and cost will be reduced.
Design freedom
Unlike rigid boards, flexible circuits are not limited to two dimensions. Since they are as flexible as wires or ribbon cables, the options for flexible circuit design are endless. At flexible circuits, we are proud to be able to meet the most complex design challenges. The design of flexible circuits can meet highly complex and unimaginable configurations while being able to operate in the harshest environments. Flexible circuit design may require any of the following：
- Highly complex configuration
- Withstand harsh operating environments
- Single and double combination
- Complex interconnection
- Shield
- Rigidity/Flexibility
- Surface mount equipment
Flexibility during installation
Flexible circuits allow the use of a third dimension because they can be interconnected between two or more planes during execution. Therefore, they solve space and weight issues that rigid boards cannot match. Flexible circuits can be operated multiple times during installation and execution without electronic failure.
High density applications
Flexible circuits allow extremely narrow lines, giving way to high-density device clusters. Dense device counts and lighter conductors can be designed into products, freeing up space for other product features.
Improve airflow
Due to its streamlined design, flex circuits allow cooling air to flow through electronic applications.
Increase heat dissipation
Flexible circuits allow for shorter thermal paths due to their large surface area to volume ratio and compact design. Additionally, the thinner design of the flex circuit allows heat to dissipate from both sides of the circuit.
Improve system reliability
In the past, most circuit failures occurred at interconnection points. Flexible circuit designs can reduce interconnections, thereby increasing circuit reliability.
Point-to-point line replacement
Depending on the number of point-to-point connections in a circuit design, at Flexible Circuits, we guarantee that a single flex circuit can be designed and built to eliminate many, if not all, of these interconnections. At Flex Circuits, “We go where others don’t go.”
Reliability and durability
In designs with moving parts, flexible circuits can move and bend up to 500 million times without failure. Polyimide’s excellent thermal stability also enables circuits to withstand extremely hot applications. The thermal stability of polyimide provides a better foundation for surface mounting than rigid boards. Because a compliant base film places less stress on the solder joint, thermal mismatch is less likely to occur.
repeatable route
Our circuits are made from accurate reproductions of artworks with superior manufacturing consistency. Etched circuitry replaces soldering and hand-wiring connections to rigid boards, eliminating wiring errors.
Simplified circuit geometry
Flex circuit technology places surface mount electronics directly on the circuit, simplifying the overall design. Complex patterns that are nearly impossible to achieve using rigid circuit boards can be easily achieved in flexible circuits.
Package size and weight reduction
Multiple systems on a rigid board create more weight and utilize more space. Flexible circuits contain the thinnest dielectric substrates. The thinness allows for a streamlined design, eliminating the need for bulky rigid panels. Elasticity and flexibility can reduce package size. In addition to reducing package size, reducing package weight is another benefit. As the demands of the electronics industry continue to increase, weight reduction allows flexible circuits to remain very competitive.

Multi Layer Flex Applications
Static application
Flex circuit bending is only used in applications where the circuit is mounted and installed into its application (also known as flex installation or flex installation). Static applications are typically performed using less expensive electroplated (ED) copper.
Dynamic bending applications
A situation where the flexible circuit itself bends dynamically (repeatedly) during actual use of the final product. Common examples include flip phones, laptops, printer heads, and robotic arms. Dynamic applications require the use of roll annealed (RA) copper.

flexible printed circuit manufacturers Products Pre-Production
Shanyo’s in the production process, to prevent too many open and short circuits caused by low yield or reduce drilling, calendering, cutting, and other rough process problems caused by the FPC board scrap, replenishment problems, and assess how to choose the material to achieve the best results for customers to use the flexible circuit boards, pre-production pre-processing is very important.
Pre-production pre-processing needs to deal with three aspects, these three aspects are completed by engineers.
FPC board engineering assessment, the company’s production capacity to meet customer board requirements and unit costs.
Engineering assessment through, immediately preparing materials to meet the raw material supply of each production process.
Engineer customer’s CAD structural drawings, Gerber line data, and other engineering documents to deal with, to suit the production environment and production specifications of the production equipment.
Production drawings MI (engineering process card) and other information are delegated to the production department and various departments such as clerical control, procurement, etc., into the regular production process.
