Title: Alfred Groeber: Innovator in Semiconductor Technology
Introduction
Alfred Groeber is a notable inventor based in Stockdorf, Germany. He has made significant contributions to the field of semiconductor technology, holding a total of 2 patents. His innovative approaches have paved the way for advancements in flexible printed circuits and fine structures for semiconductor contacting.
Latest Patents
Groeber's latest patents include a method for the manufacture of fine structures for semiconductor contacting. This method involves photographic structuring on both sides of a smooth, non-stressed metal tape, which is then etched from both sides. A single-sided metal deposition occurs through float-type electroplating, and stabilization of the fine structure is achieved by depositing lacquer or resin via electrophoretic deposition or electro-immersion lacquering. The insulator carrier is applied as one of the final steps of the process.
Another significant patent is for flexible through-contacted printed circuits. This invention features a flexible printed circuit board with conductors on opposite sides, which are through-contacted by die-punching the board to create an angularly-displaced tongue portion. Solder is flowed to contact both conductors, and a terminal pin can be inserted through the board to connect a component. The angularly-displaced tongue ensures reliable mechanical and electrical contact in the soldered joint.
