Flexible circuit designs share many of the same challenges as rigid PCB designs, but there are also many differences and additional challenges. The very nature of a flex circuit being able to bend and flex make it as much a mechanical device as an electrical one. This creates a special set of requirements unique to flexible circuitry. Understanding how these requirements interact will allow the PCB designer to create a flex circuit that balances the electrical and mechanical features into a reliable, cost effective interconnect solution. We hope you find this flex circuit design guide a useful tool throughout your design process. We also encourage you to call one of our knowledgeable, experienced Applications Engineers at any time during your design process. They stand ready to assist you at every step to ensure that your flex circuit design is a successful one.
