    Abstract: A method is provided for forming a plurality of solder joints for electrically and mechanically coupling a printed circuit board (100) and a flexible circuit (101). Solder is applied to the connection surfaces of the printed circuit board (100), and the connection surfaces of the flexible circuit (101) are tinned. The circuit board (100) and flexible circuit (101) are then positioned so that the connections surfaces of each are in alignment and a gap exists between circuit board (100) and the flexible circuit (101). The gap between circuit board (100) and flexible circuit (101) is precisely controlled and permits the solder of the printed circuit to be in contact with the connection surfaces of the flexible circuit (101). The solder is reflowed by applying heat by vapor phase condensation.

    Abstract: In a process for cooling soldered objects, a liquid is applied on the soldered objects and made to evaporate quickly. In a preferred embodiment, the objects soldered in a vapour phase soldering installation are cooled down as soon as they leave the vapour phase by means of the vapour phase soldering liquid. The advantages of the process are that the soldered objects can be cooled much more quickly and that the quality of the soldering joints is improved.

    Abstract: The invention describes a process and a device for wave and/or reflow soldering in the form of vapour-phase soldering for electronic units. In prior art processes and devices, either wave soldering or vapour-phase soldering alone can be performed in a single chamber. For electronic units which contain both components which are to be wave soldered and those to be reflow soldered, at least two soldering devices and two process steps are necessary. There is the further drawback that temperature-sensitive components impose either a limitation on the soldering temperature and hence the solders which can be used or laborious post-fitting. The invention performs wave soldering and vapour-phase soldering as a form of reflow soldering in a single chamber, in which an electronic unit can be placed and/or the portion of the volume of the chamber filled with the saturated vapour of a primary fluid can be controlled in such a way that, at the worst, temperature-sensitive components of the unit lie only partly in the saturated vapour and the connections of the electronic components of the unit are in the saturated vapour during soldering. The invention permits the soldering of surface-fitted, penetrating and temperature-sensitive components, e.g. large electrolytic capacitors, in a single chamber and in a single process stage and is therefore eminently suitable for economical mass production with high soldering quality.

    Abstract: The invention relates to a transport device and process for loading and removing the part to be soldered in a vapour-phase soldering installation, in which a support for the part to be soldered is taken in its original direction into and out of a medium container for vapour-phase soldering and a plurality of sealing valves prevent soldering vapour from escaping. The advantages of the invention lie in the simple and economical production of the transport device and low soldering medium consumption.

    Abstract: Workpieces, in particular printed circuit boards or subassemblies equipped with circuit elements, are cleaned after soldering by washing them with an inert cleaning fluid the temperature of which is maintained slightly below the melting point of the solder. This obviates the use of pollutant solvents to dissolve impurities and fluxes. This cleaning process is particularly advantageous after vapour-phase soldering, because the cleaning liquid used can be the same as that used as a heat-transfer medium in the vapour-phase soldering installation. This resolves the problem of undesirable mixing of different treatment media (heat-transfer medium and cleaning liquid).

    Abstract translation: 工件,特别是装有电路元件的印刷电路板或子组件在焊接之后通过用温度低于焊料熔点的惰性清洗液冲洗来清洁。 这样可以避免使用污染物溶剂来溶解杂质和助熔剂。 由于所使用的清洗液可以与在气相焊接设备中作为传热介质使用的清洗液相同,所以这种清洗过程在气相焊接之后是特别有利的。 这解决了不同处理介质(传热介质和清洗液)的不合要求的混合问题。
