Patent number: 10332552Abstract: A suspension baseplate is stamped at its distal end to which the load beam is mounted. The stamping operation smoothes out roughness in the edge of the baseplate and lowers its height slightly so that, along the line on the baseplate which last contacts the load beam as the load beam is leaving the baseplate, that line on the baseplate is smooth and free of burrs and similar defects. By eliminating burrs on the surface to which the load beam is mounted, variations in the pitch and twist of the load beam are reduced.Type: GrantFiled: December 4, 2017Date of Patent: June 25, 2019Assignee: Magnecomp CorporationInventor: Keith A. Vanderlee

Patent number: 10276195Abstract: In a gimbal dual stage actuated (GSA) suspension for a disk drive, a viscoelastic damper is disposed between and adhered to the suspension's PZT microactuator and the flexure trace gimbal. The damper is dispensed in fluid form onto the trace gimbal during assembly of the suspension, the PZT is placed onto the damper, and the damper is then hardened leaving it adhered to both the PZT and the trace gimbal. The damper reduces peaks in the frequency response of the PZT actuation, thus allowing higher bandwidth of the servo control loop and increasing the effective read and write speeds for the suspension.Type: GrantFiled: February 12, 2018Date of Patent: April 30, 2019Assignee: Magnecomp CorporationInventors: Kuen Chee Ee, Long Zhang, Keith A. Vanderlee

Patent number: 10032466Abstract: A vibration damper for a disk drive suspension includes a viscoelastic damping layer, a substantially stiffer polymer constraining layer, and a metal layer interposed between the viscoelastic layer and the polymer constraining layer, such as a thin layer of aluminum vapor deposited onto the polymer constraining layer. The metal layer hides irregularities in the viscoelastic layer as that viscoelastic layer is adhered to the suspension without introducing potentially contaminating mineral particles into the polymer constraining layer.Type: GrantFiled: November 1, 2016Date of Patent: July 24, 2018Assignee: Magnecomp CorporationInventor: Keith A.

Patent number: 8320083Abstract: An electrical interconnect and a method of making an electrical interconnect in which a conductor has been substantially plated with a first protective metal shell, such as nickel, and a second outer metal shell, such as gold, before a covercoat has been applied. Such an electrical interconnect can be characterized as having an even-thickness outer shell on both its terminal pads and underneath the covercoat adjacent to the terminal pads, without overhangs or gaps near the bottom of the covercoat caused by surface etching during production.Type: GrantFiled: December 6, 2007Date of Patent: November 27, 2012Assignee: Magnecomp CorporationInventors: Christopher Dunn, Keith A.

Patent number: 5509200Abstract: Method and apparatus for fabricating fine pitch pattern multilayer printed circuit boards involving laminar stackable board layers providing power distribution, signal distribution and capacitive decoupling. In one respect, the invention relates to the fabrication of board layers by beginning with a metallic core, patterning the core, selectively enclosing the core in a dielectric, selectively depositing metal to form vias, plugs and signal lines, and forming dendrites with joining metallurgy on the vias and plugs to provide stackable connection from above or below the plane of the board layer. In another aspect, the invention is directed to the use of a sol-gel process to form a thin high dielectric constant crystalline film onto a metallic sheet followed with a deposition of a metallic layer onto the high dielectric constant film.Type: GrantFiled: November 21, 1994Date of Patent: April 23, 1996Assignee: International Business Machines CorporationInventors: Jerome A.
