Abstract: A method is provided for a soldering process. The method can include receiving a liquid phase heat transfer medium at a preheating container. The heat transfer medium can be received from an external supply. The method can also include heating the heat transfer medium to or above a predefined temperature that maintains the liquid phase and directing the heated heat transfer medium from the preheating container to an evaporation container. In the evaporation container, the heat transfer medium can be vaporized to convert the heat transfer medium from the liquid phase to a gas phase. Further, the method can include directing the gas phase heat transfer medium from the evaporation container to a solder chamber. The soldering process occurs in the solder chamber.

Abstract: Thermodynamic fluctuations caused conventionally during introduction of a relatively cold liquid into the vapor generator can be reduced considerably or eliminated by providing a preheating region, so that the necessary amount of vapor can be provided in a substantially continuous manner. Vapor generation can here be controlled on the basis of the vapor pressure in the evaporation region, wherein advantageously during operation of a soldering system the pressure in the corresponding process chamber can also be used for control in such a manner that there is always a pressure gradient and additional conveying means, such as pumps for the vapor supply, can thereby be avoided.
