摘要： A method and system for stabilizing properties of shape memory alloy (SMA) wires in an optical image stabilization (OIS) suspension of the type having a first or support assembly and a second or moving assembly coupled with respect to one another by the SMA wires. Embodiments of the method comprise cyclically mechanically straining and de-straining the wires by moving the moving and support assemblies with respect to one another while heat is applied to the wires. The temperature, strain, and de-strain levels are configured to cause the wires to cyclically transition between austenite and martensite phases during the mechanical straining and de-straining.

摘要： Various embodiments concern a method for manufacturing a disk drive head suspension component. Such methods can comprise providing a head suspension component comprising a layer of insulating material on a spring metal layer. Such methods can further comprise forming a strain gauge element and a trace seed layer by depositing a first metal on the insulating material layer, such as by sputtering. The strain gauge element and the trace seed layer can be formed simultaneously by the depositing of the first metal as part of the same process step. The first metal can be of a strain gauge class of metal having relatively high resistivity, such as constantan. Such methods can further comprise plating a second metal on the trace seed layer to form one or more traces.

摘要： Methods for producing flexible circuits can include creating treating a surface of the flexible circuit with at least one of an atmospheric plasma and a beam of ions. The atmospheric plasma is formed by directing a flow of gas between an electrode and the surface of the flexible circuit and generating a voltage between the electrode and the flexible circuit to create a plasma from the gas. A mean ion energy of the ions in the ion beam ranges from about 500 electron volts to about 1,500 electron volts.
