Abstract: A heating head for soldering and de-soldering surface mount devices (SMD's) using hot inert gas or air is comprised of a handle in which there is placed a heater sub-assembly on which there is secured a quick connect mechanism for mounting a heating nozzle. The heater sub-assembly is enclosed in a shroud and is secured to the end of the handle by a thermal insulating ring, such shroud housing a ceramic rod having elongated bosses on which a heating element is secured, while a laminar flow equilizer is used to provide more uniform gas flow across the heating element. Quick connect mechanism is secured to the heater sub-assembly shroud and uses a spring loaded winged locking mechanism to the secure heating nozzles to the heater head. In one embodiment, the heating nozzles have a truncated pyramid shaped chamber to which individual end nozzles are attached for directing gas flow.
