Layout Considerations (Cont.)

MINIMUM RECOMMENDED FOOTPRINT FOR SUR-

FACE MOUNTED APPLICATIONS

Surface mount board layout is a critical portion of the

total design. The footprint for the semiconductor pack-

ages must be the correct size to insure proper solder

connection interface between the board and the

package. With the correct pad geometry, the pack-

ages will self align when subjected to a solder reflow

process.
