Title: Wolf-Dieter Ruh: Innovator in Plastic Sheet Technology
Introduction
Wolf-Dieter Ruh is a notable inventor based in Sindelfingen, Germany. He has made significant contributions to the field of plastic sheet technology, holding a total of 6 patents. His work primarily focuses on the production of viaholes in plastic sheets, which has applications in various electronic components.
Latest Patents
One of his latest patents involves a method for producing viaholes in glass fiber reinforced plastic sheets. This innovative technique allows for dry-etching viaholes according to a predetermined hole pattern, ensuring that the glass fiber meshing remains largely unaffected. The method is particularly useful for fabricating plastic sheets that feature unilaterally or bilaterally applied conductor patterns and viaconnectors. These components are conductively linked to the conductor patterns, enabling the creation of multilayer board laminates. The laminates are formed by alternating layers of plastic sheets carrying the conductor patterns with untreated copper sheets, which are subsequently laminated together. Such boards and plastic sheets can serve as connector boards for multilayer ceramic modules that house semiconductor chips.
