A General Overview of Flexible Printed Circuit Board Applications
Flexible printed circuit boards can be used in diverse applications from various industries. They can be designed to meet low or high volume flexing requirements with high levels of accuracy.
Basic Application Types
Flexible PCBs can be used in static as well as dynamic applications. The type of application has to be confirmed by the manufacturer before any design work is started. Understanding the type of application will also make a difference when choosing the type of materials and components used to build a PCB.
Static Application: Static applications are also known as flex-to-install, or flex-to-fit. In these types of applications, the circuits are designed with a small amount of flex. As the flexing movement is minimal, flex PCBs for static applications are designed with inexpensive Electro Deposited (ED) copper.
Dynamic Applications: Dynamic applications involve the circuit being flexed repeatedly on a regular basis. To ensure that the performance of the flex circuit board is consistent in such applications, the PCBs are designed with Rolled Annealed (RA) copper.
The flex PCB can be designed according the application requirements.
