We often see printed circuit boards (PCBs) integrated circuits (ICs), many people are "stupidly unclear" about these two concepts. In fact, they are so complicated. Today we will sort out the difference between PCB integrated circuit.

What is a PCB?

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

The current circuit boards are mainly composed of lines patterns, dielectric layers, through holes / vias, solder resistant inks (Solder resistant / Solder Mask), silk screens (Legend / Marking / Silk screen). , Surface Finish, etc.

The advantages of PCB: high density, high reliability, designability, manufacturability, testability, assembly, maintainability.

What is an integrated circuit?

An integrated circuit is a miniature electronic device component. Adopt a certain process to interconnect transistors, resistors, capacitors, inductors other components wiring required in a circuit, make it on a small several small semiconductor wafers dielectric substrates, then package them in a tube case , To become a miniature structure with the required circuit functions; all components have been integrated into a structure, making electronic components a big step towards miniaturization, low power consumption, intelligence high reliability. It is represented in the circuit by the letter "IC".

Integrated circuits can be divided into three categories: analog integrated circuits, digital integrated circuits, digital / analog hybrid integrated circuits according to their functions structures.

The integrated circuit has the advantages of small size, light weight, fewer lead wires solder joints, long life, high reliability, good performance, etc. At the same time, the cost is low, which is convenient for mass production.

The relationship between PCB integrated circuits

The integrated circuit generally refers to the integration of chips. Like the Northbridge chip on the motherboard, the internal CPU is called an integrated circuit, the original name is also called an integrated block. The PCB refers to the circuit board that we usually see, there are printed solder chips on the circuit board.

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

To put it simply, integrated circuit is a general circuit integrated into a chip, it is a whole, once there is damage inside, then the chip will be damaged, the PCB can solder components by itself, can be replaced if broken. . Double-sided multilayer circuit board
