Patent ID: 8186050

Claim:
A method for manufacturing a printed wiring board, comprising: preparing a substrate having a plurality of alignment marks including alignment marks positioned adjacent to each other; recognizing the alignment marks on the substrate by capturing images of the alignment marks using a recognition camera; and manufacturing a printed wiring board according to positions of the alignment marks recognized by the recognition camera, wherein the recognizing of the alignment marks comprises adjusting a position of the recognition camera when capturing images of the alignment marks positioned adjacent to each other such that each of the alignment marks positioned adjacent to each other is positioned equidistant from a center of an image-capturing region of the recognition camera, the printed wiring board has interlayer resin insulation layers and conductive layers which are laminated and solder-resist layers which are formed on an outermost interlayer resin insulation layers, and the solder-resist layers are formed based on the positions of the alignment marks recognized by the recognition camera.
