What is the relationship between printed circuit boards and integrated circuits

In the process of learning electronics, we often see printed circuit boards (PCB) and integrated circuits (IC), pcb stackup calculator many people are confused about these two concepts. In fact, they are not so complicated, today we will clarify the difference between PCB and integrated circuit.

What is PCB?

PCB (Printed Circuit Board), the Chinese name can be called enterprise printed circuit board, 1 oz vs 2 oz also known as printed circuit board, is an important electronic product component, is the support of electronic system components, but also the carrier of electrical equipment connection of China's electronic control components. Because it is the technology we use traditional electronic printing and production, it is called a "printed" circuit board.

At present, the circuit board is mainly composed of pattern, media, through hole/through hole, soldering/soldering cover, legend/mark/screen printing and surface treatment.

What is an integrated circuit?

An integrated circuit is a miniature electronic device or component. Transistors, resistors, capacitors, inductors and other components and wiring required in the circuit, after a certain process, are connected to each other on a small piece or several small semiconductor chips or dielectric substrates, and then packaged in the shell and pipeline to form a miniature structure with the required circuit functions, and all components are structurally integrated together. This is a big step towards miniaturization, low power consumption, intelligence and high reliability of electronic components. It is represented in the circuit by the letter "IC".

Integrated circuits can be divided into analog integrated circuits, digital integrated circuits and mixed signal integrated circuits according to their functions and structures.

The integrated system circuit design has the advantages of small volume, light weight, fewer lead lines and welding points, long life, high reliability and good performance, and low use cost, which is convenient for large-scale enterprise production.

The relationship between PCB and integrated system circuit

Integrated circuit is generally refers to the integration of the chip, like the north bridge chip on the motherboard, the CPU inside is called integrated circuit, the original name is also called integrated block. The PCB refers to the circuit board we usually see, and the welding chip is printed on the circuit board.

Understanding of the relationship between the two: The integrated circuit (IC) is welded on the PCB board; The PCB board is the carrier of the integrated circuit (IC).

In simple terms, the integrated system circuit is to integrate a national general circuit into a chip, it is through an enterprise as a whole, once it is damaged internally, the chip is damaged, and the PCB can improve itself for welding components, broken we can change components.
