Basic knowledge of printed circuit board what is PCB layout

The printed circuit board is the base plate for assembling the electronic parts. It is the printing plate of the connecting and printing elements on the common base.With the development of science and technology, the demand for electronic information processing of all kinds of products has been gradually enhanced, and the emerging electronic products have been emerging constantly, making the use and market of PCB products continuously expanding.The new generation of 3G mobile phones, auto electronics, LCD, IPTV, digital TV and computer will bring more PCB market than the traditional market.

LAYOUT is the meaning of LAYOUT planning.In general, PCB LAYOUT is the Chinese meaning of printed circuit board LAYOUT.Especially in the use of PADS9.3 or allegro16.3 schematic diagram, it is necessary to understand the common electronic components in English.

Generally speaking, we can replace a part with the first three English letters of a part. In the design training of PCB, for example, the resistance is used in the RES, the capacitance is in CAP, the inductance is used in IND,...And so on.
