Definition
  1. Noun:
    • A physical platform for electronic components: A circuit board is a flat, rigid piece of insulating material (like fiberglass) on which a pattern of conductive pathways (circuits) is printed or etched. Electronic components such as resistors, capacitors, and integrated circuits are mounted and soldered onto it to create a functional electronic assembly.
    • The main electronic foundation in a device: It serves as the primary structure for interconnecting electronic components in devices like computers, televisions, and appliances.
Examples of Usage
  • Noun:
    • The technician carefully inspected the circuit board for any damaged traces.
    • A modern smartphone contains several densely packed circuit boards.
    • The computer's capabilities were expanded by adding a new graphics circuit board.
Advanced Usage
  • "Printed circuit board (PCB)": This is the full technical term for a circuit board, emphasizing the method of creating the conductive pathways.
    • The design software is used to layout the printed circuit board before manufacturing.
Variants and Related Words
  • Motherboard / Mainboard (n): The primary circuit board in a computer, which houses the central processing unit (CPU) and provides connectors for other boards.
    • The CPU and RAM modules are installed directly onto the motherboard.
  • Expansion card / Add-in card (n): A smaller circuit board designed to be inserted into a slot on a motherboard to add specific functionality.
    • He installed a new sound card, which is a type of expansion card, to improve audio quality.
Synonyms
  • Board: A common informal shortening (e.g., "the main board").
  • PCB: An acronym for Printed Circuit Board.
  • Card: Often used for smaller, removable circuit boards (e.g., a graphics card).
Related Phrases
  • Populate a board: The process of soldering all the electronic components onto a circuit board.
    • The factory robots can populate a board in a few minutes.
  • Bare board: A circuit board that has the conductive pathways but no components attached yet.
    • The bare boards are shipped to the assembly plant.
