Title: Innovations by Klaus Horn: A Closer Look at the Inventor from Hofheim, Germany

Introduction

Klaus Horn, a prolific inventor based in Hofheim, Germany, has made significant contributions to the field of technology with a total of 14 patents to his name. His work primarily revolves around chemical solutions and processes that enhance the manufacturing of electronic components.

Latest Patents

Among his latest innovations, Klaus Horn has developed a water-soluble fluoride-containing solution designed for removing cured coatings. This unique solution is particularly effective for photo-cross-linked and thermally cross-linked photoresist masks, which are essential in the electronics industry. The formulation includes a diglycol monoalkyl ether, a glycol monoalkyl ether, an alkali hydroxide, water, and a water-soluble fluoride.

Another noteworthy patent focuses on the patterned metallisation of structured printed circuit boards (PCBs). In this process, a solder stop mask is applied to the fully structured PCB, leaving solder contact locations exposed. The solder stop mask is subjected to a controlled heating process to ensure that while hardening does not fully occur, the copper surface remains minimally oxidized. Metal is then deposited from an aqueous bath at the exposed areas, followed by sufficient heating to completely harden the mask, preventing solution infiltration during metal deposition.

Career Highlights

Klaus Horn has had an enriching career, working with notable companies such as Hoechst Aktiengesellschaft and Morton International, Inc. His experiences at these organizations have undoubtedly influenced his innovative projects and patent developments.
