The PCB Is Maintainable

- Jul 27, 2017 -

PCB is more and more widely used, because it has a lot of unique advantages, trichosanthes as follows.

can be high-density. For decades, the high density of PCB has been developed with the improvement of integrated circuit integration and installation technology.

High reliability. Through a series of inspection, PCB testing and aging tests can ensure that the PCB long-term (use, generally for 20) and reliable work.

can be designed. PCB Performance (electrical, physical, chemical, mechanical, etc.) requirements, can be designed through standardization, standardization, etc. to achieve PCB design, short time, high efficiency.

Production. The use of modern management, can be standardized, scale (volume), automation and other production, to ensure consistency of product quality.

Testability. Set up a relatively complete test methods, testing standards, PCB a variety of testing equipment and instruments to detect and identify the PCB product eligibility and service life.

can be assembled. PCB products are not only convenient for a variety of components standardized assembly, and can be automated, large-scale production. At the same time, PCB and various components assembly parts can also be assembled to form larger parts, systems, until the machine.

Maintainability。 As PCB products and components are assembled in a standardized design and large-scale production, and therefore, these components are also standardized. Therefore, PCB once the system fails, can quickly, easily, flexibly to replace, quickly restore service system work. Of course, you can say more about it. such as the miniaturization of the system, lightweight, high-speed signal transmission and so on.

What is the PCB? PCB classification

Single panel

Single panel (single-sided boards) on the most basic PCB, the parts are concentrated in one side, the wire is concentrated on the other side (there are SMD components and the wire for the same side, the plug-in device on the other side). Because the wire only appears in one side, so this kind of PCB is called Single-sided Board (single-sided). Because the single panel in the design line has many stringent restrictions (because only one side, the wiring between the intersection and must be around the path alone), PCB so only the early circuit to use this kind of board.

Double panel

Double-sided Board (double-sided boards) This circuit board on both sides of the wiring, but to use the two sides of the wire, you must have the appropriate circuit between the two sides to connect. The "bridge" between the circuits is called a guide hole (via). The guide hole is on the PCB, fills or spreads the metal the small hole, it may connect with two sides the wire. Because the area of the double-sided board is 1 time times larger than the single panel, the double panel solves the difficulty of wiring interleaving in Single panel (can pass through Kong to the other side), it is more suitable for use in the circuit which is more complex than the single panel.
