In the process of learning electronics, we often see printed circuit board (PCB) and integrated circuit (IC), many people are not clear about these two concepts. pcb stackup calculator 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. Because it is made of electronic printing, it is called a "printed" circuit board.

At present, 1 oz vs 2 oz the circuit board is mainly composed of pattern, media, through hole/through hole, soldering/soldering cover, legend/mark/screen printing, surface treatment and so on.

PCB advantages: high density, high reliability, designability, productivity, testability, assemblability and maintainability.

What is an integrated circuit?

An integrated circuit is a device or component that is electronically controlled by a micro-enterprise. Using a certain process, the transistors, resistors, capacitors and inductors required in an important circuit and wiring interconnection technology together are made on a small or several small pieces of semiconductor chips or dielectric substrates, and then packaged in a design shell to become a micro-social structure with the main functions of its own required working circuits; Among them, all these components have been structurally formed into a national whole, making electronic information components a big step forward in terms of miniaturization, low power consumption, intelligence and high reliability management. It is represented by the letter "IC" throughout the circuit.

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

Integrated circuit has the advantages of small size, light weight, less lead line and solder joint, long life, high reliability, good performance and so on, and low cost, easy to large-scale production.

The relationship between printed circuit boards and integrated circuits

Integrated circuit generally refers to chip integration, such as the north bridge chip on the motherboard, the integrated circuit inside the CPU, are called integrated circuits, the original name is also called integrated blocks. PCB refers to the circuit board that we usually see, the welded chip printed on the circuit board.

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