There are many benefits to Flexible Printed Circuits including:

Flexibility during Installation – Flexible Circuits allow a third dimension to work with because they can interconnect between two or more planes during execution. As a result, they solve space and weight problems unmatched by rigid boards. Flex circuits can be manipulated many times during installation and execution without electronic failure.

High Density Applications – Flexible circuits allow for minutely narrow lines giving way to high density device population. Denser device populations and lighter conductors can be designed into a product, freeing space for additional product features.

Improved Airflow – Because of their streamlined design, flex circuits allow for the flow of cooling air through an electronic application.
