Dimension
1. All dimensions shown are in millimeters (mm) unless otherwise noted.
2. This Land Pattern Design is based on the IPC-7351 guidelines.
3. All metal pads are to be non-solder mask defined (NSMD). Clearance between the solder
4. A stainless steel, laser-cut and electro-polished stencil with trapezoidal walls should be used
5. The stencil thickness should be 0.125 mm (5 mils).
6. The ratio of stencil aperture to land pad size should be 1:1 for all perimeter pins.
7. A 3 x 1 array of 1.30 x 0.60 mm openings on 0.80 mm pitch should be used for the center
8. A No-Clean, Type-3 solder paste is recommended.
9. The recommended card reflow profile is per the JEDEC/IPC J-STD-020 specification for
mask and the metal pad is to be 60 m minimum, all the way around the pad.
to assure good solder paste release.
