Critical Design Rules for Managing Bend Radius in Flexible PCB Applications
Introduction Flexible printed circuits are now used in everything from wearable devices and cameras to medical electronics and aerospace systems. As products become smaller and more complex, engineers increasingly rely on flex designs to save space and improve reliability. However, one of the most important factors that often gets overlooked is the flex PCB bend radius, which directly affects performance, durability, and long-term stability of the circuit. When the bend …
