We had some similar issues on one of our products.The oven profile is critical. We found that with a gradual soak ramp up it took care of about 80% of the tombstoning.The other thing that we found was pad design issues. Take a look at the sept. issu

BGA's are not difficult, but should be inspected no matter how careful you are. Here we have been doing bga's forever and x-ray 100%. Without an x-ray there is no good way to ensure the BGA is placed properly, without bridging or insufficients. If yo
