  • Plasma treatments for flexures of hard disk drives
    Patent number: 12129567
    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.
