[Flexible circuit boards](https://www.epectec.com/flex/) are necessary in numerous applications where a design requires the circuit to be bent within the electrical equipment or electronic device. However, it is not desired to have the flexible circuit board bend adjacent to connectors, mounted components, solder joints, and hole patterns. In these instances, a stiffener needs to be designed in to add rigidity and stability so that the flex circuit performs reliably.

When developing a [flex PCB based design](https://www.epectec.com/flex/design/), one of the most common early decisions is whether a flex circuit with stiffener(s) will meet the design requirements or if a rigid-flex construction is necessary or more effective. While there is some overlap between the two methodologies, there are significant capability, performance, and cost differences that require review to ensure a successful design.
