摘要： Apparatus and method for grounding a flexure of a head suspension assembly to a moving support such as an actuator arm or an E block close to a preamplifier, write driver or other wiring such as a flexible circuit located on the moving support in a disk drive assembly, including connecting a metal substrate layer of the flexure to a ground on the moving support closely adjacent the preamplifier or flexible circuit to minimize ground loop interference with signals on the traces. The invention includes a variety of arrangements to secure the metal substrate layer to the moving support.

摘要： A switchable shunt has an insulating layer separating conductive lead and spring metal layers. The shunt includes a base region formed on the spring metal layer, one or more arms formed in the conductive lead layer and at least one of the insulating and spring metal layers, one or more pad regions electrically coupled to an arm and formed in at least the conductive lead layer, and one or more gaps. Each arm extends through a gap and is resiliently biased toward a shunted state with the pad region in electrical contact with the base region. The shunt is movable to an electrically open state where the pad and base regions are electrically isolated. A method of making the shunt includes etching the shunt from laminated material and pushing the arm and pad through the gap. The shunt may be operated by applying a force to the arm.

摘要： A method of adjusting the common mode impedance while enabling maintenance of the differential mode impedance of a pair of traces located with respect to a ground plane formed by a load beam or trace assembly of a disk drive head suspension. The method includes forming a ground plane having apertures with isolated conductive islands in the apertures for setting a desired common mode impedance. The method includes a cut and try approach using sample coupons to adjust the ratio of backed area to island area to adjust the common mode impedance while maintaining the differential mode impedance by maintaining the ratio of unbacked area to the sum of the backed and island areas.
