Flexible circuit boards were originally designed as a substitute for large wire harness sizes. Simple circuit design helps solve space and weight issues that traditional wiring methods cannot solve. Flexible circuit boards were initially developed as interconnect devices, although they were first developed over 20 years ago. Designers of various applications, from car audio and cameras to pacemakers and disk drives, benefit from FPCB.

With the leap of technology, new products require more compact packaging, finer impedance, and error free product performance. Flexible circuit boards provide packaging engineers with a method to miniaturize circuits, increase functional capacity, and improve reliability. In addition to being flexible, flexible boards can also be designed to meet highly complex special configurations, with sufficient flexibility to easily withstand harsh operating environments.

The new product needs to save space and weight, and have higher reliability. Due to these demands, flexible circuit board technology with a 20-year history has matured.
