Abstract
Abstract A castellated nozzle for connecting a plurality of microelectronic leads to an associated plurality of contact pads and method of using the same. The castellated nozzle includes a body having a plurality of castellations protruding therefrom, with each of the castellations having a contact surface thereon. A channel is formed adjacent to at least one castellation of the plurality of castellations. An opening extends through the body for introducing a heated gas therein. The contact surfaces of the plurality of castellations are aligned to a respective plurality of leads. Typically, the castellated nozzle includes a first plurality of castellations forming a first row and a second plurality of castellations forming a second row.
