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. A channel is formed adjacent to at least one castellation. The first and second plurality of castellations are arranged in a staggered format wherein at a first point along the length of the opening one of the castellations in the first row is located opposite to one of the channels of the second row, and wherein at a second point along the length of the opening one of the channels in the first row is located opposite to one of the castellations in the second row. An opening is formed between the first and second row. The castellated nozzle includes a hole for aligning the castellated nozzle to a flexible circuit carrier.
