In the world of electronics manufacturing, rigid circuits play a fundamental role in the design and fabrication of printed circuit boards (PCBs). These circuits, also known as rigid PCBs, serve as the backbone of electronic devices and systems, providing a sturdy platform for mounting components and facilitating the flow of electrical signals. In this article, we'll explore the basics of rigid circuits, their construction, and their applications in various industries. 1. Construction of Rigid Circuits Rigid circuits are typically composed of a rigid substrate material, such as fiberglass epoxy laminate, commonly referred to as FR4. The substrate provides mechanical support and insulation for the circuit traces and components mounted on the board. Copper traces are etched onto the substrate to create the conductive pathways that connect the various components and form the circuit. These traces are typically plated with solder to facilitate component attachment during assembly.
