Vicor VI Chip problems

Is anybody using Vicor VI Chips (SMT version)? We are using a number of these on some of our boards and are having inaccurate placement and insufficient solder issues (8 mil step stencil still not enough).

If you are placing these devices: 1. Which pick and place machine are you using 2. Are you having insufficient solder on the leads 3. Are you using chip bond adhesive under the part

Thank you!
