Method for configuring component library in PCB

The present invention discloses a method for configuring a component library in a PCB and belongs to the field of component library design and configuration. According to the method for configuring the component library in the PCB, a plurality of data tables containing component information are arranged to separately correspond to PCB component libraries; and the corresponding data table of the PCB component library is loaded according to a user demand, and the PCB component library required by the user is configured, so that the problems of library management efficiency and quality caused by that different users use different libraries and different projects use different libraries are better solved, the error rate is reduced, and the design quality and efficiency are improved.
