What is a PCB?
A Printed Circuit Board (PCB) is the backbone of electronic devices. It provides a physical base and electrical pathways for components to connect and communicate. Made of insulating material with conductive copper traces, PCBs replace traditional wiring, making circuits compact and efficient.
Types of PCB
Single-Layer PCB
Has only one conductive layer.
Simple and cost-effective.
Used in calculators, toys, and power supplies.
Double-Layer PCB
Conductive layers on both sides.
Allows more complex circuits.
Found in LED lighting, amplifiers, and industrial controls.
Multilayer PCB
Three or more conductive layers stacked together.
High performance and compact.
Used in smartphones, computers, and aerospace electronics.
Rigid PCB
Made of solid, inflexible material.
Durable and long-lasting.
Common in motherboards and medical devices.
Flexible PCB
Can bend and twist without breaking.
Lightweight and space-saving.
Used in wearables, foldable phones, and medical implants.
Rigid-Flex PCB
Combines rigid and flexible sections.
Reduces weight and increases reliability.
Used in military, aerospace, and medical devices.
