Abstract: Approaches to pre-forming solder bumps, such as for use in electrically connecting a head slider and a suspension assembly for a hard disk drive, involves applying a height stabilizer plate over a shared solder paste applied over a substrate housing electrode pads, and reflowing the solder paste with the plate applied to create solder bumps electrically coupled to the pads. Use of such a plate functions to stabilize and contain the solder paste and create uniform solder bumps across the series of pads, where the plate may be composed of a heat-resistant and anti-solder-wetting material. The solder bump pre-forming techniques generally enable solder bonding of extremely small electrical interconnection pads.
