A tool for grasping an electronic component that includes a first arm and a second arm resiliently joined together at one end and each separately extending to free end opposite from each other and spaced apart while at rest. The hand held tool monitoring apparatus comprises a mount, which in use of the hand held tool monitoring apparatus forms part of a hand held tool, and a monitoring component configured to be releasably attached to the mount. A modulator spread-spectrum modulates the base frequency of the base signal to generate a modulated signal. The stator may be injection molded from an electrically non-conductive plastic and the electrically conductive surface may be formed by a molded-in metallic insert or a molded-in metallic foil insert. A plurality of second voltage supply lines are disposed to supply a ground voltage to the sense amplifier regions and are connected to the other electrode of each of the first and second decoupling capacitors. Further, provided is a method of forming a thin film pattern capable of efficiently forming a plurality of thin film patterns with different sizes on a same base with accuracy according to the thin film patterns.
