Latest Patents
One of his latest patents is a solder leveling method and apparatus. This invention provides a method and apparatus for producing flush solder fill over recessed pins and over passage holes in circuitized substrates. The process involves immersing a substrate carrying rack in a vessel of molten solder after it has been similarly immersed in a flux bath. While in the molten solder, the rack is vigorously agitated. Afterward, the rack is withdrawn from the molten solder and pivoted upwardly while positioned over the molten solder. Simultaneously, an anvil is rotated from a home position to an impact position at precisely the correct moment. With the solder still molten on the substrate surfaces, the rack is permitted to descend and is positively biased to strike the anvil, thereby dislodging any excess molten solder. A unique supporting arrangement for the rack ensures that only a minimum of mass actually impacts against the anvil while maintaining the effectiveness of the operation. Each cantilevered arm from which a rack is suspended is temporarily supported during the impacting operation, after which the support member is withdrawn. Additionally, a solder pot of unique design and operation is provided to assure rapid, complete heating of substrates while eliminating contamination by dross and oxides.
