The data acquisition unit is used to acquire the original printed circuit board design data, wherein the original printed circuit board design data includes information of multiple layer names and multiple hole structures. The data parsing unit signal is connected to the data acquisition unit, and is used to parse the original printed circuit board design data to calculate the sorting method of multiple layers in the original printed circuit board design data. The information adding unit signal is connected to the data parsing unit, and is used to record the original information of the original printed circuit board design data, and add the calculated and adjusted information to the recorded information, wherein the recorded information includes the sorting method.

[0005] According to the above-mentioned printed circuit board design data conversion device, the printed circuit board design data conversion device further comprises a layer homing unit. The layer homing unit signal is connected to the layer adjustment unit, and according to the recorded information, the multiple layers that are flipped upside down are restored to order and marked.
