What Is a PCB?

PCBA are the foundation of modern electronic devices. They mechanically support and electrically connect electronic components. The boards themselves are made of laminate material, such as fiberglass or composite epoxy, and contain conductive pathways that connect different parts of the board. These pathways are printed or inscribed onto the board according to the predetermined PCB design.

Materials Used

The substrate material for PCBs is usually fiberglass, composite epoxy or another laminate material. The conducting material on one or both sides of the board is most often copper. The printed circuits, which are plated or etched onto the substrate according to the design, are also made of copper. The circuits are coated with tin-lead to prevent oxidation. PCBs have contact fingers on their outer edges, which are also coated with tin-lead, as well as other materials, such as nickel and gold, to increase conductivity.

Applications

PCBs are used in,a wide range of electronic devices including consumer electronics, heavy machinery, robotics, vehicle components and medical equipment. Examples include:

• Computers
• Cell phones
• TVs
• Radios
• Printers
• Calculators
• Appliances
• Lighting systems
• Medical imaging systems
• Pacemakers
• Engine management systems
• Industrial controls
• Telecom towers
• Data storage equipment
• Satellite systems
