The Complexities of Designing with Fine Pitch BGAs

Date: Thursday September 6 2018

Time: 8.00 am registration for 8.30 am start   Finish 12.30 pm


Designing with BGAs is much more complex than in the past! The ball pitches are going down and the total pin counts and package sizes are going up, making everything more demanding. With those changes, the signal integrity and EMI issues become more profound, the fanout and routing are much more challenging, and the power connections more difficult. Adding to that are the manufacturing concerns unique to these parts that have surfaced from small pad openings and the ways we make the connections in larger BGAs that don’t work as well in fine pitched parts. In this presentation, we will discuss all of those things and more, including placement and stackups for components and caps, gridded and non-gridded patterns for parts and routing, and both through hole and microvia fanout possibilities. This class has lots of illustrations and examples!
