PCB Is Designable Aug 21, 2017


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

Can be assembled. PCB is not only for the standardization of various components assembled, PCB 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.

 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, PCB 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, PCB a variety of test equipment and instruments to detect and identify PCB product qualification and service life.

PCB material

Material is simply said: the object looks like what texture. PCB material can be seen as a combination of material and texture. PCB In the circuit board, PCB refers to the use of materials used in the manufacture of circuit boards, including substrates, substrate parameters, processes and so on. Mainly refers to the substrate, copper foil and adhesive composition of CCL (copper) quality.

PCB material composition

PCB is the main material from the substrate, copper foil and adhesive composition of the CCL (copper). The substrate is composed of a polymer resin and a reinforcing material. The surface of the substrate is covered with a layer of pure copper foil with high electrical conductivity and good weldability. PCB The thickness is 35 ~ 50 / ma. The copper foil is covered with the substrate One side of the CCL is called single-sided copper clad laminate, both sides of the substrate are covered with copper clad copper clad, said double-sided CCL; copper can be firmly covered on the substrate, the adhesive to complete. Common CCL thickness of 1.0mm, 1.5mm and 2.0mm three.
