PCB board Features:

1. High density: For decades, with the increase of integrated circuit integration and advancement of mounting technology, the development of high-density printed circuit boards has been very good.

2. High reliability: Through a series of inspections, tests and aging tests, the PCB can be guaranteed to work reliably for a long time.

3. Designability: For electrical, physical, chemical, mechanical and other PCB performance requirements, printed circuit board design can be achieved through design normalization and standardization, with short time and high efficiency.

4. Producibility: Through modern management, standardization, scale, automation and other production can be carried out to ensure consistent product quality.

5. Testability: Established relatively complete test methods, testing standards, various test equipment and instruments, etc. to detect and identify the qualification and service life of PCB products.

6. Assemblability: PCB products are not only convenient for standardized assembly of various components, but also for automated, large-scale mass production. At the same time, the assembled parts of PCBs and various components can be assembled into larger parts and systems up to the entire machine.

7. Maintainability: Since PCB products and various component assembly parts are standardized in design and mass production, these parts are also standardized. Therefore, once the system fails, it can be replaced quickly, easily and flexibly, and the system service can be quickly restored. Of course, we can give more examples, such as making the system smaller and lighter, and speeding up signal transmission.

Integrated Circuit Features

Integrate circuits have the advantages of small size, light weight, fewer leads and solder joints, long life, high reliability and good performance, etc. In addition, the cost is low, which facilitates mass production. It is widely used not only in industrial and civilian electronic equipment, such as radio cassette recorders, televisions, computers, etc., but also widely used in military, communications, remote control, etc. The use of integrated circuits to assemble electronic devices can increase assembly density by several tens to thousands of times over transistors, and can greatly improve the stable working time of device.

Difference between PCB Board and Integrate Circuit

Integrated circuit usually refers to the integration of chips. For example, the Northbridge chip on the motherboard, the internal CPU is called an integrated circuit, and the original name is also called the integrated module. Printed circuit refers to the circuit boards that we usually see, and there are printed solder chips on the circuit board.

Integrated circuits are carriers that are soldered to the PCB. Printed circuit boards can be found in almost every electronic device. If there are electronic parts in a certain device, the printed circuit boards are mounted on PCBs of different sizes. In addition to fixing various small parts, the main function of the printed circuit board is to carry out the electrical connection of the top various parts.

In short, integrated circuits are general circuits integrated on a chip. It is a whole, and once the integrated circuit is damaged, the chip will also be damaged. The PCB can solder components by itself, and components can be replaced if the component is broken.
