[0002] Circuit boards are important electronic components, supporting bodies for electronic components, and carriers for electrical connections of electronic components. Because they are made using electronic printing technology, they are called "printed" circuit boards. Their main function is to connect various electronic components through circuits, playing the role of conduction and transmission. They are key electronic interconnects for electronic products. Almost every electronic device cannot do without printed circuit boards, because they provide mechanical support for the fixed assembly of various electronic components, realize wiring and electrical connections or electrical insulation between them, and provide the required electrical characteristics.
