Question 1: What is part packaging and what is the difference between it and parts?

　　Answer: (1) Part packaging refers to the appearance and solder joint position indicated when the actual part is soldered onto the circuit board.

　　(2) Part packaging is only the appearance and solder joint position of the part, and pure part packaging is only a concept of space, so different parts can share the same part packaging; On the other hand, the same type of part can also have different packaging, such as RES2 representing resistance, which has packaging forms such as AXAIL0.4, AXAIL0.3, AXAIL0.6, etc. Therefore, when using welded parts, it is not only necessary to know the part name but also the packaging of the part.

　　(3) The packaging of parts can be specified during circuit design or when introducing network tables. When designing a circuit diagram, you can specify it in the Footprint settings in the Part Properties dialog box, or you can also specify the part packaging when importing a network table.

　　Question 2: What is the difference between wires, flying wires, and networks?

　　Answer: Wires, also known as copper film wiring, are used to connect various solder joints and are the most important part of printed circuit boards. Printed circuit board design revolves around how to arrange wires.

　　Another type of wire related to a wire, often referred to as a flying wire or pre tensioning wire. Flywire is a type of connection generated by the system according to rules after introducing a network table, used to guide wiring.
