What is a PCB circuit board

What is a PCB circuit board?
PCB (PrintedCircuitBoard), the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Because it is made by electronic printing, it is called a "printed" circuit board.
How much do you know about the circuit board?
What are the advantages of PCB circuit boards?
After electronic equipment adopts printed boards, due to the consistency of similar printed boards, manual wiring errors can be avoided, and electronic components can be automatically inserted or installed. Mounting, automatic soldering, and automatic inspection ensure the quality of electronic equipment, improve labor productivity, reduce costs, and facilitate maintenance.
How are PCB circuit boards classified?
Classified according to the number of circuit layers: PCB single-sided board, PCB double-sided board and PCB multi-layer board. Common multilayer boards are generally 4-layer boards or 6-layer boards, and complex multilayer circuit boards can reach dozens of layers.

What are the advantages of PCB circuit boards?
The reason why PCB circuit board can be used more and more widely, because it has many unique advantages, the general is: high density, high reliability, designability, manufacturability, Testability, assemblability, maintainability, etc.
What is the PCB circuit board production process?
Cutting, inner layer, lamination, drilling, copper sinking, circuit, drawing, etching, solder mask, characters, spray tin (or sinking gold), gong edge, v cutting (not required for some PCB circuit boards), Flying test, vacuum packaging, etc.
What is the welding process standard?
PCB circuit board Static electricity protection method during welding: leakage and grounding.
Soldering process: clean the components to be removed, heat the solder feet with an electric soldering iron, clean the solder feet with a tin suction device, remove the old components, put in the new components correctly, heat the solder feet, move the solder wire, and move Open the solder wire and remove the electric soldering iron.
Check the solder joints: whether the solder joints are round, bright and firm, and whether they are connected to the surrounding components.
