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.
