Understanding Rigid PCBs: Structure, Benefits, and Industrial Applications
Printed circuit boards (PCBs) are the silent enablers of modern electronics, providing the foundation for electrical connections in everything from medical devices to aerospace systems. Among the various PCB types, Rigid PCB are the workhorses of the industry, delivering unmatched stability and durability. Unlike flexible or rigid-flex alternatives, rigid PCBs are built to hold their shape under extreme conditions, making them indispensable for devices that require unwavering reliability. This article dives deep into what makes rigid PCBs essential, exploring their structure, advantages, and real-world applications. What is a Rigid PCB? A Rigid PCB is a non-flexible circuit board designed with a solid substrate that prevents bending or distortion. These boards act as a structural and electrical backbone, ensuring all components stay firmly in place, even under mechanical stress or temperature fluctuations. The base material, usually FR4 fiberglass, metal-core, or ceramic, dete...
