Abstract:
Many packaging concepts use via arrays for grounding and to eliminate parasitic modes. Such arrays represent periodic structures and change their behavior beyond a certain frequency. Proper design of via geometry and pitch is necessary. For this purpose, electromagnetic simulation data and an equivalent circuit model are presented.
