Frequency domain measurements of VSPA: a novel packaging technology

This paper describes the modeling and measurement of VSPA, a very small peripheral array package developed by Archistrat containing 320 pins with a size of 27 mm/spl times/27 mm. The analysis covers a frequency range of 20 MHz-3 GHz, includes analytical calculations, simulations, measurements, leading to a lumped model representation of the package parasitics.
