Meaning and Definition
A thin board made of insulating material with conductive pathways (circuits) printed or etched onto it, onto which electronic components like chips and resistors are mounted.
The fundamental physical platform for mounting and connecting electronic components in almost all modern electronic devices. Also refers to the field of design, manufacturing, and testing of such boards. Abbreviated as PCB.

Differences
No significant lexical differences. Spelling of related terms (e.g., 'colour' vs. 'color') may differ in surrounding documentation.
Connotations
Identical. Purely technical term.
Frequency
Identical in technical contexts. The abbreviation 'PCB' is equally frequent in both variants.

FAQ
Frequently Asked Questions
It is almost always pronounced as the three individual letters: P-C-B.
A motherboard is a specific type of printed circuit board. It is the main, largest PCB in a computer, which holds the CPU, memory, and provides connectors for other boards. All motherboards are PCBs, but not all PCBs are motherboards.
Yes, to some extent. Damaged traces can be bridged with wire, and faulty components can be desoldered and replaced. However, damage to the internal layers of a multilayer board or severe physical cracks often renders the PCB unrepairable.
The green colour comes from the 'solder mask'—a protective lacquer-like layer that prevents solder bridges and protects the copper traces. Green is the traditional, most common colour due to historical military specifications and good contrast for inspection, but PCBs can be red, blue, black, or other colours.

Mnemonic
Think of a **PRINTED** city map (**CIRCUIT** layout) on a flat **BOARD**, where the streets are copper tracks and the buildings are electronic components.
Conceptual Metaphor
THE ELECTRONIC DEVICE IS A CITY: The PCB is the city's map and infrastructure (roads/power lines), components are buildings, and electrical signals are traffic.
