The components that often appear in electronic products are IC (Integrated Circuit) and PCB. Although they are related, their uses, construction and manufacturing processes are different.

What is IC?
An integrated circuit (IC) is a miniature electronic component that is a combination of transistors, resistors, capacitors and diodes integrated into a single chip. IC is the "brain" of most electronic devices, performing tasks such as processing data and controlling circuits.

Main features of IC:
Miniaturization: IC combines millions of electronic components into a small silicon chip.
High functionality: Each IC is designed for a specific purpose.
Material: The core of IC is mainly made of silicon, which acts as a semiconductor.
Packaging: IC is packaged in a protective casing with pins or pads for connecting to other components.

Role of IC:
IC is the heart of electronic systems and is responsible for performing necessary operations in devices such as computers, smartphones and TVs.

What is PCB?
PCB) is a flat plate made of fiberglass with conductive pathways etched on the surface. PCB provides a platform for mounting and electrically connecting components such as IC, resistors, capacitors and connectors to create a complete electronic circuit.

Key Differences Between IC and PCB

Aspect IC (Integrated Circuit) PCB (Printed Circuit Board)
Purpose Performs a specific function, such as processing or control. Provides a platform to connect and arrange components.
Structure A small silicon chip with micro-components embedded inside. A flat board with conductive traces and mounted components.
Functionality Acts as the "brain" of the circuit. Acts as the "body" holding all components together.
Material Made primarily of silicon and encapsulated in resin. Made of fiberglass, copper, and insulating materials.
Complexity Contains millions of micro-components in a tiny space. Consists of layers of conductive and insulating materials.
Manufacturing Requires advanced semiconductor fabrication techniques. Manufactured through processes like etching, drilling, and soldering.
Applications Found inside chips for computation, memory, or control tasks. Found in almost every electronic device, connecting components.


Conclusion
IC is the functional core of an electronic device, responsible for performing tasks. PCB is the basic platform to which all components (including IC) are connected.
