What is the full form of PCB?
Show Hint
Modern PCBs are manufactured in multiple layers (from 2 layers up to 10+ layers in advanced smartphones), with internal copper traces laminated between thin sheets of fiberglass to route complex signals cleanly in a very small space.

Solution and Explanation
Step 1: Identifying the Acronym:
The full form of PCB in electronics engineering is Printed Circuit Board.
Step 2: Understanding PCB Construction:
A Printed Circuit Board is a rigid, non-conductive flat board (typically made of FR-4 fiberglass) laminated with thin sheets of copper.
- The copper is chemically etched to form conductive pathways (traces) that connect different electronic components.
- Components (such as resistors, capacitors, and ICs) are soldered onto conductive pads on the board to establish a reliable, compact, and organized circuit.
