SiP System-in-Package Design and Simulation

Mr. Suny Li (Li Yang) is a SiP/PCB Technical Specialist in China; he now works in AcconSys Technology Co. Ltd, (a Mentor Authorized Distributor for China). Suny has guided and consulted on dozens of SiP projects in China, accumulating plentiful experience in SiP design and simulation. Suny has 10 years' experience in and knowledge of Application Engineer for Mentor, especially in SiP/PCB design and simulation. Before this, Suny worked in the Chinese Academy of Science and SIEMENS for several years. He has more than seven years' experience in hardware design (HW system design, PCB layout, high–speed signal integrity, power integrity, EMI, etc.). In the course of his work, Suny has published papers and acquired four patents, and he continues with this work. Suny is a senior member of the Chinese Institute of Electronics (CIE) and a member of the IEEE. Suny graduated from Beijing University of Aeronautics & Astronautics (BUAA) in 2000, receiving Master's and Bachelor's degrees in Science and Technology of Aeronautics & Astronautics.
