Notes: General  
1. All dimensions shown are in millimeters (mm) unless otherwise noted.  
2. This land pattern design is based on IPC-7351 guidelines.  
Note: Solder Mask Design  
1. All metal pads are to be non-solder mask defined (NSMD). Clearance  
between the solder mask and the metal pad is to be 60 µm minimum, all  
the way around the pad.  
Notes: Stencil Design  
1. A stainless steel, laser-cut and electro-polished stencil with trapezoidal  
walls should be used to assure good solder paste release.  
2. The stencil thickness should be 0.125 mm (5 mils).  
3. The ratio of stencil aperture to land pad size should be 1:1 for the  
perimeter pads.  
4. A 2x2 array of 1.10 x 1.10 mm openings on 1.30 mm pitch should be  
used for the center ground pad.  
Notes: Card Assembly  
1. A No-Clean, Type-3 solder paste is recommended.  
2. The recommended card reflow profile is per the JEDEC/IPC J-STD-020  
specification for small body components.
