Company Description At Bosch, we shape the future by inventing high-quality technologies and services that spark enthusiasm and enrich people’s lives. Our promise to our associates is rock-solid: we grow together, we enjoy our work, and we inspire each other. Join in and feel the difference. The Robert Bosch GmbH is looking forward to your application! Job Description: Modern automotive systems operate at data rates exceeding 16 Gb/s, where small variations in PCB materials can significantly affect signal integrity. One important effect is resin skew, caused by the inhomogeneous distribution of glass fibers and resin in PCB laminates. Differential signals propagating over glass bundles versus resin pockets experience different propagation velocities, leading to timing skew and potential eye-diagram degradation. This internship investigates measurement-based characterization of resin skew using dedicated high-speed PCB test structures. The goal is to design, simulate, and analyze differential test structures that allow quantifying skew induced by glass weave and resin distribution. The work contributes to developing standardized measurement structures for reliable high-speed interco...
