Abstract: A method for selecting a ferrite bead for a filter to avoid a peak value in a frequency response curve of the filter is provided. The method includes the steps of: building an equivalent model database including parameters of equivalent models of ferrite beads, the parameters including an inductance and a capacitance of a corresponding equivalent model of each ferrite bead; calculating parameters of a desired ferrite bead in the filter based on parameters of the filter, the parameters of the ferrite bead including an inductance, a capacitance, and a resonant frequency; adjusting parameters of the filter until the calculated resonant frequency equals or approaches a desired resonant frequency, and finding an inductance and a capacitance respectively equaling or approaching the calculated inductance and the calculated capacitance in the database; and selecting a ferrite bead with the appropriate inductance and capacitance as found in the database for the filter.

Abstract: A wet etching method for making calibration bump disks for use in providing quality control of production run magnetic hard disks is disclosed. It includes the steps of: (a) coating a layer of bump material on a substrate; (b) coating a photoresist layer on the layer of bump material; (c) exposing the photoresist layer to a light source under a photomask; (d) developing the photoresist layer using a developer solution to form an undeveloped photoresist layer; (e) etching the substrate containing the layer of bump material and the undeveloped photoresist layer to remove portions of the layer of bump material not covered by the undeveloped photoresist layer; and (f) stripping the undeveloped photoresist layer to leave at least a bump on the substrate which was originally covered by the undeveloped photoresist layer. The wet etching method eliminates many of the problems observed from the conventional metal mask method, including the elimination of the convex-shaped bump surface.
