Characteristics and differences of PCB board and integrated circuit

2020-01-04 11:12:54

Features of PCB board

1. Can be high density: For decades, the high density of printed boards can be developed with the integration of integrated circuits and advances in installation technology.
2. High reliability: Through a series of inspections, tests and aging tests, it can ensure that the PCB can work reliably for a long time (usage period, generally 20 years).
3. Designability: For various performance (electrical, physical, chemical, mechanical, etc.) requirements of the PCB, printed board design can be achieved through design standardization, standardization, etc., with short time and high efficiency.
4. Producibility: Adopt modern management, can carry out standardization, scale (quantity), automation and other production to ensure consistent product quality.

5. Testability: Established relatively complete test methods, test standards, various test equipment and instruments to test 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 automated and large-scale mass production. At the same time, PCB and various component assembly parts can be assembled to form larger parts and systems, up to the whole machine.
7. Maintainability: Since PCB products and various component assembly components are standardized design and large-scale production, these components are also standardized. Therefore, once the system fails, it can be replaced quickly, easily and flexibly, and the s
ystem can be quickly restored to service. Of course, you can give more examples. Such as making the system smaller and lighter, and speeding up signal transmission.

Characteristics of integrated circuits  

The integrated circuit has the advantages of small size, light weight, fewer lead wires and solder joints, long life, high reliability, good performance, etc. At the same time, the low cost 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 in military, communications, remote control, etc. The use of integrated circuits to assemble electronic equipment can increase assembly density by several tens to thousands of times over transistors, and the stable working time of the equipment can be greatly improved.

Difference between PCB board and integrated circuit

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, and the original name is also called an integrated block. The printed circuit refers to the circuit boards and the like that we usually see, and there are solder chips printed on the circuit boards.

Integrated circuit (IC) is soldered on the PCB; the PCB is the carrier of the integrated circuit. The PCB board is a printed circuit board (PCB). Printed circuit boards are 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 electrically connect the various parts on it.

To put it simply, an integrated circuit is a general circuit integrated into a chip, which is a whole. Once there is damage inside, the chip is also damaged. The PCB can solder components by itself, and can be replaced if it is broken.
