    Abstract: A method for forming an electrical interconnection between a slider pad and a suspension pad that is adjacent to and positioned at an angle relative to the slider pad, which includes the steps of forming a solder bump on a first surface of the slider pad, reshaping the solder bump into a protrusion having an ellipsoidal shape that extends from the slider pad and contacts the suspension pad, and applying a laser to the ellipsoidal protrusion to reflow the solder bump while simultaneously applying a downward pressure to the solder bump in order to form a solder fillet between the slider pad and the suspension pad.

    Abstract: A method for interconnecting multiple components of a head-gimbal assembly with a solder joint, including the steps of positioning a first component adjacent to and at an angle relative to a second component to provide a connection area between the first and second components, dispensing a solder sphere to a capillary tube having tapered walls, wherein the capillary tube is positioned with an exit orifice above the connection area between the first and second components, pressurizing the capillary tube until a predetermined pressure is reached, applying a first laser pulse to the solder sphere to liquefy the solder sphere until it falls from the exit orifice, waiting for a predetermined time period after the liquefied solder sphere has exited the exit orifice of the capillary tube, and applying a second laser pulse to reflow the solder sphere to create the solder joint between the first and second components.

    Abstract: A method for interconnecting multiple components of an electrical assembly with a solder joint, including the steps of positioning a first component adjacent to a second component to provide a connection area, dispensing a solid solder sphere to a capillary tube, wherein the capillary tube is positioned with an exit orifice above the connection area between the first and second components, applying a first laser through the capillary tube while measuring light from the first laser that reflects off the connection area as the solder sphere moves through the capillary tube, and applying a second laser to at least partially melt the solder sphere when the measured light decreases to a predetermined level and as the solder sphere falls from the exit orifice toward the connection area between the first and second components.

    Abstract: An apparatus includes a slider body with a first portion formed of a first insulating material and a second portion formed of a second insulating material that is different from the first insulating material. The second portion of the slider body is at a trailing edge of the slider body and the second portion includes a bearing surface and a top surface opposite the bearing surface. A plurality of bond pads are disposed on the top surface of the second portion such that an entire bottom surface of each of the plurality bond pads is attached to the top surface of the second portion.

    Abstract: A magnetic recording head including a trailing surface and a plurality of bond pads in a row, each of which is spaced by a gap from an adjacent bond pad along a width of the trailing surface. Each bond pad includes two side edges spaced from each other across a width of the bond pad, wherein a width of the gap between adjacent bond pads is defined by one side edge of each of two adjacent bond pads, and a top edge extending between the two side edges. The head further includes at least one solder dam including a nonwettable, electrically conductive solder material positioned adjacent to the top edge of at least one of the bond pads.
