Delivering On Power During HPC Test


The industry’s insatiable need for power in high-performance computing (HPC) is creating problems for test cells, which need to deliver very high currents at very consistent voltage levels through the power delivery network (PDN). In response, ATE, wafer probe, and contactor vendors are introducing some innovative approaches and test procedures that can ensure robust power delivery to ATE pro... » read more

Distribution of Currents In Via Arrays


It has become increasingly difficult in recent years to provide adequate PDNs on a PCB. The sheer number of different voltages, combined with increased current demands, makes distributing current around the board a substantial layout challenge. This paper demonstrates that by using appropriate and accurate simulations, combined with the improved intuition that such simulations bring, it is a ch... » read more
