Printed circuit board (PCB), also known as circuit board, is an important electronic component and is known as the "mother of electronic components". The following is the common sense of PCB circuit boards that PCB people must understand:

1. Traditional circuit boards are circuit diagrams and drawings made by printing resists, so they are called printed circuit boards and printed circuit boards. At present, most circuit boards are attached to the attached anti-corrosion agent (laminate or coating), and the etching of the circuit board can only be carried out after exposure and development.

2. The circuit board is divided into single-sided, double-sided and multi-layered boards. On the most basic PCB, the parts are concentrated on one side and the wires are concentrated on the other side, which is called a single-sided PCB. The double-sided panel has copper cladding and traces on both sides, and can conduct the lines between the two layers through vias to form the required network connection. Multilayer board refers to a printed board with more than three conductive pattern layers and insulating materials between them, and the conductive patterns are interconnected as required.

3. The circuit board is mainly composed of pads, through holes, mounting holes, wires, components, connectors, fillers, electrical boundaries, etc. The main functions of each component are as follows:

(1) Pads: Metal holes for soldering components.
(2) Through holes: including metal through holes and non-metal through holes, where metal through holes are used to connect pins between components of each layer.
(3) Mounting holes: used to fix the circuit board.
(4) Conductor: A network of copper films used to connect component pins.
(5) Connector: Used to connect components between circuit boards.
(6) Filler: Applying copper wire to the ground network can effectively reduce impedance.
(7) Electrical boundary: used to determine the size of the circuit board.
NOTE: All components on the board must not exceed boundaries.

4. The working principle of the circuit board is: use the board-based insulating material to isolate the surface copper foil conductive layer, so that the current flows in various components along the pre-designed route to complete tasks such as work, amplification, attenuation, modulation, demodulation , encoding and other functions.

The role and function of PCB in various electronic equipment 1. Pad: Provide mechanical support for the fixing and assembly of various electronic components such as integrated circuits. 2. Wiring: realize wiring and electrical connection (signal transmission) or electrical insulation between various electronic components such as integrated circuits. Provide the required electrical characteristics, such as characteristic impedance, etc. 3. Green oil and silk screen: Provide solder mask graphics for automatic assembly, and provide identification characters and graphics for component insertion, inspection, and maintenance.

The above is a few common sense PCB circuit boards that PCB people must understand. How much do you know?
