The present invention provides a method and apparatus for the dry fluxing
of at least one component and/or solder surface via electron attachment.
In one embodiment, there is provided a method for removing oxides from
the surface of a component comprising: providing a component on a
substrate wherein the substrate is grounded or has a positive electrical
potential to form a target assembly; passing a gas mixture comprising a
reducing gas through an ion generator comprising a first and a second
electrode; supplying an amount of voltage to at least one of the first
and second electrodes sufficient to generate electrons wherein the
electrons attach to at least a portion of the reducing gas and form a
negatively charged reducing gas; and contacting the target assembly with
the negatively charged reducing gas to reduce the oxides on the
component.
