  • Microstructure patterned surfaces for integrated lead disk drive head suspensions
    Patent number: 10783908
    Abstract: Disk drive head suspension components having microstructured surfaces and a method for making the components. One embodiment of the method includes depositing a layer of photoimageable polymer having an associated set of process parameters including a minimum resolution and exposing the photoimageable polymer through a photomask having a microstructure-producing region with features below the minimum resolution for the photoimageable polymer. The exposed photoimageable polymer is developed to produce a layer of polymer having a thickness and a microstructured surface region with depressions that are less than the thickness of the polymer. In one embodiment the photomask has a microstructure-producing region with features sized and spaced between about 1 ?m and 10 ?m. Microstructured surfaces on structures such as flying leads, flying termination pads, cover coat layers and at insulating layer-trace interfaces and insulating layer-cover coat interfaces can be manufactured.

  • PLASMA TREATMENTS FOR FLEXURES OF HARD DISK DRIVES
    Publication number: 20160329067
    Abstract: 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.
