circuit card

A technician installs a circuit card into a computer's motherboard.

Definition

Noun: A circuit card is a flat, rigid board made of insulating material, onto which electronic components and conductive pathways are mounted or printed. It is designed to be inserted into a specific slot or connector within a larger electronic system, such as a computer, to add or enhance its functionality.

Usage

A circuit card is a modular component that expands or customizes the capabilities of an electronic device. It is installed by plugging it into a matching expansion slot or connector on the device's main board (motherboard).

Examples
  • The technician installed a new circuit card to add a high-speed network connection to the server.
  • Many older computers allowed users to upgrade their graphics by replacing the video circuit card.
  • The sound stopped working, so we suspect a problem with the audio circuit card.
Advanced Usage
  • "To populate a circuit card": This refers to the manufacturing process of soldering or attaching all the necessary electronic components (like chips, resistors, and capacitors) onto the blank board.
    • The factory line is used to populate the circuit cards before testing.
Variants and Related Words
  • Printed Circuit Board (PCB): This is the more general term for the physical board itself, which may or may not be designed as a removable "card." All circuit cards are PCBs, but not all PCBs are circuit cards (e.g., a smartphone's mainboard is a PCB but is not removable).
  • Expansion Card: A very common synonym, emphasizing its function of expanding a computer's capabilities.
  • Adapter Card: Another synonym, often used when the card provides an interface or adaptation to a specific standard (e.g., a USB adapter card).
  • Daughterboard: A smaller circuit card that attaches to a larger main board to provide additional features.
Synonyms
  • Expansion board
  • Add-in card
  • Interface card
Related Phrases
  • "To seat a circuit card": To install it firmly and correctly into its slot.
    • Make sure you seat the circuit card properly to avoid connection issues.
  • "A faulty circuit card": A card that is not functioning correctly.
    • The system error was traced back to a faulty circuit card.
