Title: Heinz-Wilhelm Pfannekuche: Inventor of a Uniform-Coating Apparatus.
Introduction
Heinz-Wilhelm Pfannekuche is an inventor associated with Hanau, Germany, and Leybold Aktiengesellschaft. His recorded patent concerns an apparatus designed to produce coatings with a uniform thickness profile through cathode sputtering.
Latest Patents
Pfannekuche is credited with 1 patent: “Apparatus for the Production of Coatings of Uniform Thickness Profile on Substrates.” The invention describes a substrate carriage guided by rollers and driven through a coating chamber. Substrate disks mounted on the carriage rotate as it passes a row of permanent magnets. The magnets induce currents in magnetic disks connected to the substrate disks’ pivot shafts, causing the disks to rotate during the coating process. This arrangement is intended to help produce coatings with a uniform thickness profile.
Career Highlights
Pfannekuche’s documented patent work is associated with Leybold Aktiengesellschaft, a company known for vacuum technology and coating equipment. His invention addresses the movement and rotation of substrates during cathode sputtering.
Collaborations
Thomas Bathon and Karl Eckert are identified as Pfannekuche’s coworkers. The available information does not specify their roles in developing or patenting the apparatus.
Conclusion
Heinz-Wilhelm Pfannekuche’s recorded invention applies coordinated substrate movement and magnetically induced rotation to support uniform coating production by cathode sputtering.
