Some embodiments of the present invention provide a system which supports a dual-purpose aperture for an electronic device. The discharge angles of said orifices as projected into a horizontal plane each preferably has a phase difference of from 5 to 120 relative to those of adjacent orifices. The at least one substrate includes a plurality of wiring layers overlapped as a whole. The database is configured to store the order for the component, the information for the asset tag, and the location of the asset tag on the component. Preferably but not necessarily both warp control sections are driven by a common drive.
