Apparatus for generating a negatively charged ionic reducing gas

摘要

The present invention provides an apparatus (50) for the dry fluxing of at least one component and/or solder surface via electron attachment. The apparatus (50) generates a negatively charged ionic reducing gas and comprises:
an enclosure defining an interior hollow wherein at least a portion of the enclosure comprises an anode (54) connected to a first voltage level;
a magnetic coil (51) residing either within or outside of the interior hollow, wherein the magnetic coil (51) is connected to an energy source;
a gas inlet (22,56) and a gas outlet (23,57) that is in fluid communication with the interior hollow; and
a cathode (52) residing within the interior hollow and interposed between the gas inlet (56) and the gas outlet (57) wherein the cathode (52) is connected to a second voltage level which has a negative bias relative to the first voltage level.
