In this article, what is the relationship between PCB and integrated circuit?

In the process of learning electronics, we often see printed circuit boards (PCBS) and integrated circuits (ics), pcb stackup calculator and many people do not know the difference between these two concepts. In fact, they are not that complicated, and today we will clarify the difference between PCBS and integrated circuits.

What is PCB?

PCB(Printed Circuit Board), the Chinese name is called printed circuit board, also known as printed circuit board, is an important electronic component, is the support of electronic components, is the carrier of electrical connection of electronic components. 1 oz vs 2 oz Because it is made of electronic printing, it is called a "printed" circuit board.

The current circuit board, Mainly by the control line and Pattern (Pattern), Dielectric layer (Dielectric), hole (Through hole/via), Solder resistant ink (Solder Mask), Legend /Marking/Silk screen) and Surface Finish.

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".

According to the different functions and structures, integrated circuits can be divided into three categories: analog integrated circuits, digital integrated circuits and hybrid digital analog integrated circuits.

The integrated circuit has the advantages of small size, light weight, less lead and solder joints, long life, high reliability and good performance.

The relationship between PCB and integrated circuit

Integrated system circuit generally refers to the integration of the chip, like the north bridge chip on the motherboard, the internal management of the CPU is called the integrated control circuit, and the original name is also called the integrated block. PCB refers to the circuit board that we can usually see in our country, and the technology of welding a chip on the circuit board.

Understand the relationship between the two: The integrated circuit (IC) is welded to the PCB board, which is the carrier of the integrated circuit (IC).

In simple terms, integrated circuit is to integrate a general circuit into a chip, which is a whole. Once the inside is damaged, the chip will be damaged, and the PCB can weld components on its own. If it breaks, it can be replaced.
