The impact of HDI and microvias on PCB design

What impact do HDI via structures have on PCB design metrics? Andy Kowalewski describes a recent experiment. A PCB’s density has traditionally been seen as a function of the trace and space geometry and the number of signal layers. Emerging technologies such as microvias and buildup fabrication may force us to rethink this formula. In […]
