printed circuit

Thân thiện

A technician inspects a printed circuit under a bright light.

Definition

Noun: 1. A type of electronic circuit board: A printed circuit is a flat board, typically made of a non-conductive material like fiberglass, which has thin layers of copper "printed" or etched onto its surface to form the electrical pathways (conductors) that connect electronic components. 2. The foundational structure for modern electronics: It serves as the physical platform upon which components like resistors, capacitors, and integrated circuits are mounted and electrically interconnected, replacing the need for complex hand-wired connections.

Usage Examples

• Noun:
  • The technician repaired the device by replacing the damaged printed circuit.
  • Modern manufacturing relies on automated machines to assemble components onto a printed circuit.
  • The design of the printed circuit is crucial for the device's speed and reliability.

Advanced Usage

• "printed circuit board (PCB)": This is the full and most common term. "Printed circuit" often implicitly refers to the complete board assembly.
  • The heart of the computer is its main printed circuit board, often called the motherboard.
