A couple things to look at.. Are you using Pb-Free solder? What are the leads of the SD Connector tinned with? Do you have a thermal profiler to use to verify your oven profile? (If not, you may be able to ask a Sales Rep to come in and assist y

The smaller ball "missing" from the lower left is from solder migrating down into the adjacent via. The solder mask may have been damaged or missing prior to mounting the BGA device. The larger balls at the top right are due to uneven heating during
