Andre, Use a footprint per IPC-7351. Your assembly engineer will need to specify home plate or H shaped stencil apertures. As long as the process is good, you shouldn't have tombstoning problems with 0402. Download an IPC-7351 land pattern calculator here: http://www.mentor.com/products/pcb-system-design/pcbmatrix But make sure you also get a copy of IPC-7351, to help understand the information you need to input to the calculator, and how calculations are done, in case you need to tweak any settings.
