Abstract
A flow control nozzle for hot gases includes an input end to receive a hot gas. An output end of the flow control nozzle delivers the hot gas to a surface mount device attached with solder to a printed circuit board. A gas distribution mechanism is positioned between the input end and the output end. A gas flow control mechanism is positioned in the gas distribution mechanism to selectively alter the flow of the hot gas through the gas distribution mechanism such that the gas distribution mechanism and the gas flow control mechanism operate to deliver the hot gas to the output end in a substantially uniform manner that facilitates substantially uniform melting of the solder.
