  • Robert Hanson, MSEE has unmatched experience in teaching and knowledge of electronics. As a Testability Overseer for Boeing Commercial Airline products, Mr. Hanson has worked with non-EEs and EE’s. His over 40 years of work experience in the design manufacturing and testing areas have enabled him to consult and train both nationally and internationally. As a digital design engineer at The Boeing Company, Rockwell, Honeywell, and Loral, Mr. Hanson designed and provided prototype operational analysis on many high-speed designs, including PCBs for AWACs, B1-B, 747-400, missiles, and ground support test equipment. He has played a very active role in automating the line, implementing robotics and participating in produciblity studies, and working in the CAE/Cad/CAT, JIT , simulation and automatic assembly environments. He also has performed studies and headed research projects in the computer-integrated manufacturing environment. Mr. Hanson has extensive experience in the testing disciplines (both factory and field, commercial and military). His teaching experience include electronic conventions, over 100 private companies on site, and universities. Boeing Company awarded him Aerospace Man of the Year for saving $6,000,000 for inventing a new testing technique for the Boeing B-1 bomber electronics.
