A printed circuit board (PCB) is a fundamental component in modern electronics. It serves as a mechanical base to hold and connect the components of an electric circuit, allowing for the creation of complex electronic system.
What is a PCB?
A Printed Circuit Board (PCB) is an electronic assembly that uses copper conductors to create electrical connections between components. It provides mechanical support for electronic components, allowing a device to be mounted in an enclosure. Altium
PCBs are the backbone of most electronic devices, enabling the functionality of everything from simple gadgets to complex computing systems.
Types of PCBs
PCBs come in various types, each suited for specific applications:
Single-Layer PCBs
-
Contain only one layer of conductive material.

PCB Materials and Layers
PCBs are composed of several materials and layers:Informa TechTarget
Substrate
-
The base material, usually fiberglass, provides mechanical support.Altium
Copper Layer
-
Conductive layer that forms the circuit paths.ABL Circuits+1Wikipedia+1
Solder Mask
-
Protective layer that prevents solder bridges.
Silkscreen
-
Used to add labels and markings for component placement.
The number of layers in a PCB can vary depending on the complexity of the circuit. Multi-layer PCBs allow for more intricate and compact designs.
