A clasp for an ornamental object comprising a base, a top, and a link. The movable bracket is equipped with a driving device. The method further comprises determining a schematic diagram page and path that is associated with the determined at least one physical component, determining schematic diagram children pages and paths that are associated with a common parent page and path of the at least one physical component, determining the schematic diagram parent page and path of the at least one physical component. The trimming electrodes are sequentially trimmed one-by-one, by, for example, irradiating a laser beam, starting from a trimming electrode closer to an edge, whereby the inductance of the coil is increased accordingly.
