BGA Breakouts & Routing
By Charles Pfeil
(Published May 2008)
There are many benefits to using the BGA package; however its greatest asset - the ability to provide an extremely dense array of thousands of pins - also turns out to be a tremendous problem for PCB designers. The BGA density and pin count continues to increase; yet, our ability to effectively design with these devices has not kept pace.
Fortunately, significant advancements in PCB fabrication technology have enabled further miniaturization in the manufacturing process. These improvements, along with new software and design methods specifically for BGAs provide a means to successfully design using these devices. This book explores the impact of dense BGAs with high pin-count on PCB design and provides solutions for inherent design challenges.
