Abstract: A copper plating structure and a package structure including the same are provided, and the copper plating structure includes at least one first copper layer and at least one second copper layer. The first copper layer includes a (111) crystal plane, wherein a proportion of the (111) crystal plane in each of the first copper layers is 36% to 100%. The second copper layer is located on the first copper layer and includes a non-(111) crystal plane or includes a (111) crystal plane and a non-(111) crystal plane, wherein a proportion of the (111) crystal plane in each of the second copper layers is 0% to 57%.

Abstract: A method for capturing a tool path, applicable to a machine tool having a controller and furnished with a tooling, includes the steps of: obtaining a data update frequency of the controller; calculating a feed rate of the controller, determining whether or not the feed rate is obtained, going to next step if positive, and going to the previous step if negative; reading G-codes of the controller to confirm the feed rate; and, based on the confirmed feed rate, recording machine coordinates transmitted from the controller for synthesizing a tool path file. The tool path file is used for simulation and analysis of machining of the machine tool. In addition, a device for capturing the tool path is also provided.
