1. All dimensions shown are in millimeters (mm) unless otherwise noted.
2. Dimension and Tolerancing is per the ANSI Y14.5M-1994 specification.
3. This Land Pattern Design is based on the IPC-SM-7351 guidelines.
4. All dimensions shown are at Maximum Material Condition (MMC). Least Material Condition (LMC) is
5. All metal pads are to be non-solder mask defined (NSMD). Clearance between the solder mask and the
6. A stainless steel, laser-cut and electro-polished stencil with trapezoidal walls should be used to assure
7. The stencil thickness should be 0.125 mm (5 mils).
8. The ratio of stencil aperture to land pad size should be 1:1 for all perimeter pads.
9. A 4x4 array of 0.80 mm square openings on a 1.05 mm pitch should be used for the center ground pad.
10. A No-Clean, Type-3 solder paste is recommended.
