Common Industrial Applications of Printed Circuit Boards (PCBs)

Printed Circuit Boards (PCBs) are a central component in nearly every modern electronic device. They provide a physical and electrical infrastructure for connecting electronic components and enable the flow of electricity and precise control of mechanical and digital operations.

PCBs serve various purposes across different industries—here we present the main ones. We’re here to help you understand just how essential these components are at the core of modern industry.

What Are Printed Circuit Boards?

Printed Circuit Boards are boards made of insulating materials (usually fiberglass) with conductive pathways (such as copper) printed on them. PCBs replace complex wiring and enable easy, compact, and reliable connections between electronic components.

PCBs can be simple (single-layer) or complex (multi-layered) depending on the application. These are the most common types:

• Single-layer PCBs: Used in simple devices like electronic toys, remote controls, and basic household gadgets.
• Double-layer PCBs: Enable routing on both sides of the board to save space and create more efficient current paths.
• Multi-layer PCBs: Contain multiple layers of conductors separated by insulating layers. Designed for advanced systems requiring high performance.
• Flexible PCBs (Flex PCBs): Made from flexible materials that allow bending and use in tight spaces or devices with non-standard shapes.
• Rigid-Flex PCBs: A combination of rigid and flexible boards designed for advanced use in medical, defense, and consumer electronics industries.
