In modern electronic equipment, PCB (Printed Circuit Board) is ubiquitous; it is a key component of electronic products, as the human body's nervous system is connected a variety of electronic components connected to ensure the normal operation of the equipment. Today, let us explore the PCB to understand its mysteries.

(A) the definition and function
PCB is a board-like structure made of insulating materials, with the printed conductive lines, pads, etc., to achieve electrical connections between electronic components. It not only provides physical support for electronic components, but also is responsible for signal transmission and power distribution, and is the basis for electronic products to achieve a variety of functions.

(B) structure and composition
PCB is usually composed of substrate, copper foil, solder resist layer, silk screen layer, and other parts. Substrate as a support structure, common materials such as FR-4 (glass fiber reinforced epoxy resin); copper foil after etching to form a conductive line; soldermask layer is used to prevent solder adhesion in unwanted places to ensure the accuracy of the welding; silkscreen layer is used to mark the component identification, line number and other information to facilitate production and maintenance.

(C) a variety of types
According to the number of layers, PCB can be divided into a single panel, a double-sided board, and a multilayer board. Single-panel only one side of the conductive lines, simple structure, lower cost, commonly used in some simple electronic equipment, such as calculators, etc.; double-sided board both sides of the line, through the hole to achieve the electrical connection between the two sides of the application is more widely used, such as several small home appliances control boards; multilayer boards contain more than one conductive layer, generally used in complex electronic products, such as computer motherboards, cell phone motherboards, etc., the more layers, the more powerful the functions can be achieved, the stability of signal transmission. The more layers, the more powerful the function, the higher the stability of signal transmission. In addition, there are flexible PCBs, which can be bent, folded, commonly used in wearable devices, laptop display wiring, etc., to meet the miniaturization of electronic products, lightweight and foldable design needs.
