This re-design centered around a 676 ball BGA component. A total of 23 of the balls on the BGA were not connected where they needed to be. The only viable solution involved re-routing. That's a significant re-design under any circumstances. It would have been easier if the pads that required re-routing were on the perimeter of the BGA layout, but such was not the case.

Watch a short video that shows our robotic BGA component reballing capabilities. Our high-reliability BGA Reballing service can quickly rework BGA components that require reballing. Reballing is most often required when the alloy of the BGA component solder balls needs to be changed from lead-free to leaded. Every BGA Reballing project is completed to meet IPC and JEDEC specifications.
