Title: John W Holdren, II: Innovator in Circuit Board Technology
Introduction
John W Holdren, II is a notable inventor based in Marietta, GA (US). He has made significant contributions to the field of circuit board manufacturing. His innovative approach has led to the development of a unique masking agent that enhances the production process of printed circuit boards.
Latest Patents
Holdren holds a patent for a Non-ionic circuit board masking agent. This water-soluble, non-ionic masking agent is specifically designed for use in the manufacture of printed circuit boards. The masking agent effectively masks portions of the circuit board to prevent the adhesion of solder, flux, and similar materials. It comprises a water-soluble non-ionic binder resin, a cellulosic non-ionic filler, a non-ionic surfactant, at least one non-ionic associative thickener, and deionized water. Importantly, the masking agent can be easily removed from the circuit board after manufacturing, ensuring that further wash water processing remains effective. Its non-ionic nature prevents agglomeration or clumping in downstream ion-exchange or filtration media.
Career Highlights
Holdren is currently employed at Illinois Tool Works Inc., where he continues to innovate and contribute to advancements in circuit board technology. His work has been instrumental in improving manufacturing processes and product quality.
