In the field of electronic design, schematic diagram and PCB design are the cornerstones of product development, but it is inevitable to encounter various problems in the design process. If not checked in time, it may affect the performance and reliability of the circuit board. This paper will list the common mistakes in schematic diagram and PCB design and organize them into a practical quick check list for reference.

1. Common mistakes in schematic design① ERC report pin has no access signal.
I/O attributes were incorrectly defined for the pins when the package was created.
Inconsistent grid properties were modified when creating or placing components, resulting in pins and wires not connected.
When creating a component, the pin direction is reversed and the connection is wrong.
(2) the component ran out of the drawing.
The component was not created in the center of the library chart paper.
③ The network table of engineering documents can only be partially transferred to PCB.
Global was not selected when generating netlist.
④ When using a multi-part custom component.
Misuse of annotate function.
2. Common mistakes in PCB design① Report that NODE was not found when the network was loaded.
Components in the schematic diagram use packages that are not available in the PCB library.
Components in the schematic diagram use packages with inconsistent names in the PCB library.
The components in the schematic diagram use packages with inconsistent pin number in the PCB library.
(2) when printing can't print to a page.
The PCB library was not set at the origin when it was created.
There are hidden characters out of bounds of PCB.
③ DRC reporting network is divided into several parts.
The network is not connected, so you need to use CONNECTEDCOPPER to find it.
