- FIG. 1 is a flowchart showing a method for inserting components on a PCB board according to an embodiment of the present invention, which is as follows:
- plug-in program data is acquired.
- Plug-in data exists in various plug-in files, for example, plug-in files with the suffix NCD, UDR, POD.
- the plug-in data is obtained by reading these program files.
- the file with the suffix NCD records the coordinates of all the operating points, and the file with the suffix named UDR records the machine type corresponding to the control data item (STEP) in the plug-in. Therefore, the suffix is UDR.

- step S104 the invalid STEP is deleted. There may also be some invalid in the plugin. STEP. As an embodiment of the present invention, invalid STEP is deleted. Since STEP is not valid when the G value is not 0, the STEP is invalid. When multiple plug-ins are split into the plug-in, it is possible to judge whether STEP is invalid according to the G value, and thus delete all invalid STEPs.
