MINIMUM RECOMMENDED FOOTPRINT FOR SURFACE MOUNTED APPLICATIONS
Surface mount board layout is a critical portion of the total
design. The footprint for the surface mount packages must be
the correct size to ensure proper solder connection interface
between the board and the package. With the correct
footprint, the packages will self-align when subjected to a
solder reflow process. It is always recommended to design
boards with a solder mask layer to avoid bridging and
shorting between solder pads.
