Title: The Innovations of Robert C. Pfahl, Jr.
Introduction
Robert C. Pfahl, Jr. is a notable inventor based in Glen Ellyn, IL (US). He has made significant contributions to the field of electronic assembly cleaning, holding a total of six patents. His work focuses on developing non-azeotropic solvent mixtures that improve the cleaning process for electronic components.
Latest Patents
Among his latest patents is a method for electrical assembly cleaning using a non-azeotropic solvent. This innovative approach utilizes a distillable 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 significant patent is the non-azeotropic solvent composition for cleaning and defluxing electrical components, which follows a similar methodology to ensure effective cleaning.
