FPCmanufacturer talk Flex circuits can easily be termed as circuits which are flexible or can flex.  Flexible circuits are basically made from a thin insulating polymer film with a pattern of conductive traces mounted bonded onto the substrate.  Flex circuits have been in use since the Second World War and they’re applications are still growing exponentially.

PCBsupplier talk there are many benefits of flex circuits which make them more useful compared to traditional cables and rigid boards.

· There is a huge decrease in assembly errors as the design is accurate and the production is fully automated.

· They require less labor and reduce production errors.   There is also a decrease in assembly time and costs.

· Flex circuits can be designed freely to meet all complex configurations.   This is because of the flexibility it holds.   The elastic nature also allows placement around edges and folds.

· They reduce weight and take lesser space.   Flex circuit boards contain the thinnest substrate materials.   They can be as thin as 0.004 inches.   This also reduces package size.

· The flexible nature also helps to reduce and absorb the impacts of any vibration.

· They are suitable for use in harsh environments.   The thinner flex circuits also allow for increased heat dissipation.   Similarly the streamlined flow allows for the flow of cooling air leading to improved airflow.

· There is minimal use of mechanical connectors.   There is also lesser use of interconnection points so the system is proven to be more reliable.

· Rigid circuit boards require fewer parts and interconnections.   Rigid circuits can also be built on complex configurations with reduced interconnections.

· The rigid flex circuits also are proven to be denser with lighter components leaving additional space for more features.

These are advantages of FlexiblePCBs!
