适用范围：This part of IEC 61188 provides information on land pattern geometries used for the surfaceattachment of electronic components with gull-wing leads on two sides. The intent of theinformation presented herein is to provide the appropriate size, shape and tolerances ofsurface mount land patterns to ensure sufficient area for the appropriate solder fillet, and alsoallow for inspection, testing and reworking of those solder joints.Each clause contains a specific set of criteria such that the information presented isconsistent, providing information on the component, the component dimensions, the solderjoint design, and the land pattern dimensions.
