  • Patent number: 10500662
    Abstract: The invention relates to a device for feeding a stream of hot gas to a printed circuit board during convection soldering in a soldering installation. The feed device comprises a nozzle plate (1) having at least one drilled hole (3), which opens into a hot gas nozzle (2) arranged on the nozzle plate (1) and having a nozzle opening (4). The invention is defined in that the hot gas nozzle is formed by a flexible helical spring (2). The invention permits the nozzle plate with the hot gas nozzles to be advanced right up to the printed circuit board under all peripheral conditions which occur. In particular, the printed circuit board can, for instance, be advanced right up to the nozzle plate even when a central support for the printed circuit boards or some other disruptive contour is present.
