  • Laser subassembly metallization for heat assisted magnetic recording
    Patent number: 9536556
    Abstract: A heat assisted magnetic recording (HAMR) assembly includes a slider, a laser diode and solder connections between the laser diode and the slider. The solder connections mechanically and electrically attach the laser diode to the slider. Each solder connection has a total volume per unit area (i.e., height) of less than or equal to about 15 ?m. The solder connections have a first intermetallic zone adjacent to the laser diode, a second intermetallic zone adjacent to the slider, and a eutectic zone of eutectic material between the first and second intermetallic zones. The eutectic zone occupies greater than or equal to about 35% of the total volume per unit area of the solder connection.
    Type: Grant

  • Ultrasonic cleaning device for removing undesirable particles from an object
    Patent number: 7111632
    Abstract: A cleaning device for cleaning an object includes an inner vessel configured to contain a first liquid and the object. The cleaning device also includes an external vessel configured to contain a second liquid and the inner vessel. The second liquid is acoustically coupled to the first liquid. At least one transducer is acoustically coupled to the external vessel and configured to generate acoustical energy which is transferred to the object through the external vessel, a second liquid, the inner vessel and the first liquid. The first liquid has a dissolved gas concentration of a first gas and the second liquid has a dissolved gas concentration of a second gas.
