ABSTRACT:
Failure of an electronic component (18) during soldering of leads (16--16) thereof to a substrate (12) can be reduced by directing a gas such as air across the top surface (13) of the substrate against the leads. The gas directed against the leads serves to drive off corrosive flux vapors which would otherwise migrate upwardly along the leads causing corrosion thereto and failure of the component.
