Abstract: The present invention is notably directed to a printed circuit board, or PCB. This PCB has two main surfaces, each delimited by lateral edges, as well as lateral surfaces, each meeting each of the two main surfaces at one lateral edge. The present PCB further comprises a row of solder pads, which extends along a lateral edge of the PCB. Each solder pad is formed directly at the lateral edge and/or directly on a lateral surface (meeting one of the two main surfaces at said lateral edge). I.e., each pad interrupts a lateral edge and/or an adjoining lateral surface. One or more chips, e.g., memory chips, can be mounted on such a PCB to form an IC package. The above solder pad arrangement allows particularly dense arrangements of IC packages to be obtained. The present invention is further directed to related devices and methods of fabrication thereof.

Labels in the images are read. The read labels are compared with specifications from a picking list, and a sort of the article is identified on the basis of the comparison. If the sort of the article does not agree with specifications from the picking list, a warning is issued. In addition, a camera system having a plurality of cameras is provided. These cameras are set up to record at least the images and to read labels in the images.
