The basic knowledge of circuit boards includes manufacturing processes such as design, printing, molding, tin spraying, and plug-in installation. Circuit boards are usually composed of substrates, conductive layers, components, solder pads, etc. According to the application field and special requirements, they can be divided into single panel, double-sided board, and multi-layer board. The design of circuit boards uses professional software such as Altium Designer or Eagle to complete circuit design and layout through a graphical interface. The production process includes making printed film diagrams, PCB manufacturing, integrity inspection, soldering components, and testing and debugging. Understanding the basic knowledge of circuit boards is helpful in selecting suitable circuit boards and improving product quality.
