Title: Innovations by Lawrence R Hagner
Introduction
Lawrence R Hagner is a notable inventor based in Naperville, IL (US). He has made significant contributions to the field of electronic assembly cleaning, holding a total of three patents. His work focuses on developing non-azeotropic solvent mixtures that improve the cleaning process for electronic components.
Latest Patents
Hagner's latest patents include a "Method for electrical assembly cleaning using a non-azeotropic solvent." This invention presents a distillable, non-azeotropic solvent mixture designed to effectively remove solder flux and other residues that were traditionally cleaned using CFC-based azeotropes. The process involves heating the mixture to a temperature that allows component A to vaporize, creating a vapor layer above the mixture. Condensing elements in the cleaning apparatus then condense this vapor, returning it to the heated mixture for further vaporization. The assembly to be cleaned is lowered through the vapor and immersed in the mixture before being positioned in the vapor again. Another patent, titled "Non-azeotropic solvent composition for cleaning and defluxing electrical," shares similar principles and applications, emphasizing the efficiency of this innovative cleaning method.
