Double Layer PCBWide Range Of Applications
Aug 22, 2017

Double-sided board on both sides of this circuit board are wiring, but to use the two sides of the wire, must be between the two sides have the appropriate circuit connection Caixing. The "bridge" between such circuits is called via. The guide hole is a small hole filled with metal on the PCB, which can be connected to both sides of the wire. Because the area of the double panel is twice as large as that of the single panel, the double panel solves the difficulty of interleaving in a single panel (which can pass through the hole to the other), which is more suitable for use on circuits that are more complex than a single panel.

Double pcb Features:

PCB has been able to get more and more widely used, because it has many unique advantages, as follows.

Can be high density. For decades, PCB density has evolved with the integration of integrated circuits and the development of technological advances.

High reliability. Through a series of inspection, testing and aging test can ensure long-term PCB (use period, usually 20 years) and reliable work.

Designable. On the PCB a variety of performance (electrical, physical, chemical, mechanical, etc.) requirements, through the design of standardized, standardized, etc. to achieve PCB design, time is short, high efficiency.

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

Testability. The establishment of a relatively complete test methods, test standards, a variety of test equipment and instruments to detect and identify PCB product qualification and service life.

Can be assembled. PCB products are easy to standardize the assembly of various components, but also can be automated, large-scale production. At the same time, PCB and various component assembly components can also be assembled to form larger parts, the system, until the machine.

Maintainability. As PCB products and various components of the assembly components are standardized design and large-scale production, so these components are standardized. Therefore, once the system fails, you can quickly, easily and flexibly to replace, quickly restore the system work. Of course, you can also put more examples. Such as the system miniaturization, lightweight, high-speed signal transmission and so on.
