Abstract
The invention relates to a machine for wave soldering or tinning comprising a solder reservoir (9); means that can form at least one solder wave with a so-called laminar form (8b); a conveyor system (2) that can bring a piece (1) to be soldered or tinned into contact with said laminar wave; and means for injecting (12) a gas in the vicinity of the wave; characterized in that the said injection means includes an injector located in a position adjacent to and downstream from the wave and provided with a wall (17) facing the solder wave, wherein the wall of the injector has at least a first group (15) of openings positioned so as to provide a first gas jet directed toward the flat surface of the solder wave.
Claims18
Wave soldering or tinning machine comprising:
- a solder reservoir (9);
- means that forms at least one solder wave having a so-called laminar form (8b);
- a conveyor system (2) that brings a piece (1) to be soldered or tinned into contact with said laminar wave;
- and
- means for injection (12) of a gas in the vicinity of the wave;
- characterized in that the said injection means includes an injector located in a position adjacent to and downstream from the wave and provided with a wall (17) facing the solder wave, wherein said wall has at least a first group (15) of openings positioned so as to produce a first gas jet directed toward the flat surface of the solder wave.
Machine according to one of the preceding claims, characterized in that the first group of openings is positioned so as to direct the first gas jet tangential to the flat surface of the laminar wave.
Machine according to one of the preceding claims, characterized in that the injector is provided with an upper wall (19).
Method for wave soldering or tinning in which the piece to be soldered or tinned is brought into contact with at least one wave of liquid solder having a so-called laminar form and a protective gas is directed over at least a portion of the wave, characterized in that the protective gas is directed over the wave by means of an injector that is located in a position adjacent to and downstream from the wave and is provided with a wall facing the wave, wherein said wall has at least a first group of openings positioned thereon so as to generate a first gas jet directed toward the flat surface of the laminar wave with the velocity of the gas emerging from the openings being between 0.5 and 30 m/s.
Device for inertization of the laminar wave of a wave soldering or tinning machine, comprising a gas injector that is located in a position adjacent to and downstream from the laminar wave and is provided with a wall facing the laminar wave, wherein the said wall has at least a first group of openings positioned on the wall so as to generate a first gas jet directed toward the flat surface of the laminar wave.
