Mandatory Internship High-Speed PCB Test Structures for Resin Skew Characterization

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 interconnect design and material selection.

• During your internship you will delve deeply into the subject matter by conducting comprehensive literature reviews on fiber optic effects and resin-induced propagation delays in high-speed printed circuit boards.
• You will independently perform precise VNA (vector network analyzer) measurements on test coupons to determine the broadband S-parameters.
• Meticulously you will analyze the measured and simulated S-parameters to precisely determine the propagation delay and differential propagation delay.
• Furthermore you will systematically investigate the influence of fiber optic weave, trace orientation, and routing geometry to uncover optimization potential.
• Lastly you will document your findings clearly and use them to develop improved characterization structures that will advance our development.

• Education: studies in the field of Electrical Engineering, Physics or a comparable
• Experience and Knowledge: experience with Python, MATLAB or similar analysis tools is beneficial
• Personality and Working Practice: you are able to approach tasks in a structured manner and develop solutions independently
• Work Routine: office attendance required
• Enthusiasm: interest in high-frequency electronics, signal integrity or electromagnetic simulation
• Languages: good in German or English

Start: according to prior agreement
Duration: 3 - 6 months (confirmation of mandatory internship required)

We offer you:

• 35 hours/week with flextime
• a permanent contact person who will accompany you during your internship
• a modern working environment, as well as mobile working by arrangement
• the opportunity to become part of our student network students@bosch Stuttgart
• discounts in our company restaurants

Requirement for this internship is the enrollment at university. Please attach your CV, transcript of records, enrollment certificate, examination regulations and if indicated a valid work and residence permit.
